Description

Technical Field

[0001] The present invention relates to the field of computer artificial intelligence, and in particular to a method and system for generating geological maps based on a large model agent. Background Art

[0002] A geological map is a scientific map that records in detail the rock types, geological structures, and stratigraphic distribution of the earth's surface in a visual way. As an important form of expression of data science on the earth's surface, geological maps not only carry rich geological information, but also play a vital role in many fields such as geological research, resource exploration, and disaster prevention.

[0003] Geological maps are important and of strategic value in the field of earth sciences due to their information integration and expression capabilities. They are a bridge connecting geological theory and practice, and have a strong demand for data production in geological surveys, academic research, and education and popular science.

[0004] However, making geological maps is a complex and delicate process, which requires cartographers not only to have a deep knowledge of geology, but also to be proficient in the operation of professional mapping software. Starting from obtaining basic geological data, cartographers need to perform a series of steps in the software, such as data loading, rendering, and element adjustment. For example, they may need to accurately georeference geological layers, adjust colors and patterns to distinguish different rock types, and add annotations and legends to enhance the readability of the map.

[0005] These operations often require a lot of time and energy, especially for professional cartographers, who may waste precious time on some basic operations. For ordinary researchers or non-professionals interested in geological maps, the threshold for making geological maps is particularly high due to the lack of professional training and experience. This not only limits the popularization and application of geological maps, but also affects the dissemination and exchange of geological information. Therefore, simplifying the production process of geological maps and lowering the technical threshold are of great significance to promoting the development and popularization of geological science.

[0006] With the rapid development of large model technology, intelligent agents based on these models have emerged, such as "Auto-GPT" and "Alibaba Cloud ModelScopeGPT". As a preliminary attempt at general artificial intelligence, these intelligent agents realize human-computer interaction through dialogue, effectively breaking the barriers of information exchange and laying the foundation for the humanized and low-threshold application of artificial intelligence.

[0007] In view of the above background, the large model agent-based method can effectively lower the user's usage threshold and simplify the tedious operation steps in the form of dialogue. This feature can well solve the current pain points in the generation of geological maps and has strong industrial application needs and prospects. Summary of the invention

[0008] In view of the problems of complex geological map production process and high professional threshold in the current geological field, the purpose of the present invention is to provide a geological map generation method and system based on a large model agent.

[0009] The object of the present invention is achieved through the following technical solution: A method for generating geological maps based on a large model agent, comprising the following steps: Define and construct a standardized geological map generation tool library, classify the geological map generation tools in the geological map generation tool library according to their uses in the mapping process, and implement and describe callable functions for a series of geological map generation tools; Upload geological map feature files, perform content verification and spatial consistency verification on supported data types, confirm the visual sorting of data, and then perform initial rendering of geological map elements according to the template; Input geological map generation instructions, identify the intent of the input instructions based on a large language model, map the instructions to geological map generation tools, perform post-processing verification on the call of the geological map generation tools, and then execute the geological map generation tools in sequence to generate geological map pieces; Export geological maps and support multiple data formats.

[0010] Furthermore, the method of defining and constructing a standardized geological map generation tool library, classifying the tools in the tool library according to their uses in the mapping process, and implementing and describing callable functions for the series generation tools includes the following steps: Define and build a standardized geological map generation tool library: According to the geological map making process and objects, the geological map tools are classified into four parts: "map initialization operation", "layer addition and rendering", "map element addition and modification", and "map saving / exporting". According to the above four types of geological map tools, relevant geological map generation tools are designed respectively, and their tool names and functional uses are clarified; Examples of the tool items are as follows:

[0011] The geological map generation tool is implemented with a callable function: Through the secondary development framework of GIS (Geographic Information System) related software, carry out coding encapsulation, implement the functions of the above generation tools, and clarify the API interface name and input parameters; In order to facilitate the scheduling of the above tools in the large model, the output types of all tool functions are unified. After each geological map generation tool is called, it will return an execution message of string type, which records whether the function is called correctly. If it is called correctly, it records the text indicating that the function is successfully called. If it is called incorrectly, it records the specific error information; In order to help the big model better understand the relationship between the user's natural language expression and the generation tool, an accurate and concise description of the above generation tools and parameters is constructed.

[0012] Furthermore, the input parameters are divided into Boolean values ​​(boolean), integers (int), floating-point numbers (float), strings and related data queues (list); wherein the Boolean value is used for displaying and hiding data and map elements; the integer is used to set the font size, line element width, font thickness, and precision, and the value should be greater than zero (the decimal place indicating precision can be zero) without special circumstances, and less than the maximum value designed for the tool; the floating-point number is used for setting map element coordinates, map element and point element size, zoom scale, and longitude and latitude interval, and the value is within the maximum and minimum value range designed for the tool; the string is used for font, style, and text information. When used for text information assignment, the string length is less than the maximum length designed for the tool. In other cases, the string exists in the form of an enumeration value; the data queue is used to describe the RGBA value of the color.

[0013] Furthermore, the geological map element file is uploaded, content verification and spatial consistency verification are performed on supported data types, the visual sorting of the data is confirmed, and then the geological map is initialized and rendered according to the template, including the following steps: Upload data and verify its data content: Upload file data in geographic spatial format, such as shapefile / geojson / kml / gml / geotif / img / csv, etc., and connect relevant geographic information services to databases, such as gdb / geodatabase / mysql / pgsql / wms / wfs / wmts, etc.; if the data content of the above file data is empty and the data cannot be read, the verification will fail, otherwise the content verification will pass; if the above geographic information service is connected to the database and the connection fails or the data cannot be obtained, the verification will fail, otherwise the content verification will pass; Perform layer sorting and spatial consistency check on the uploaded data: traverse the data type and spatial reference coordinate system of the data that has passed the content check, and prioritize the display order of the data. The priority sorting is specifically point layer-line layer-surface layer-raster image-base map service; then perform spatial consistency check on the data; Provide a geological map drawing template, which involves the difference in the existence, size, position, and layout of map elements, and select one of them as the drawing template for this geological map; wherein the map elements include the main map, map name, legend, scale, compass, latitude and longitude grid, and text annotation; Load and initially render the uploaded data: load the data in reverse order according to the determined data display order on the blank mapping template, render the data initially, render the point, line and surface layers with a random single color, and render the raster layer with grayscale stretching of the maximum and minimum values; Initialization of map elements: Initialize map elements according to different contents of loaded data. The initialization items include the compass position, scale expression value, main map viewport range, latitude and longitude range, and legend content. After the above operations are completed, the map will be presented on the interactive page of the system.

[0014] Furthermore, the spatial consistency check is specifically as follows: if the spatial reference coordinate systems of all data are consistent, no additional operation is required; if the spatial reference coordinate systems of some data are missing, and the spatial references of other data are consistent, no additional operation is required; if the spatial reference coordinate systems of the data are inconsistent, the spatial reference coordinate system of the best-ranked layer is used as a reference, and the spatial reference coordinate systems of the remaining layers are transformed into the reference coordinate system; if the spatial reference coordinate systems of some data are inconsistent and the spatial reference coordinate systems of some data are missing, the spatial reference coordinate systems of the inconsistent layers are transformed into the reference coordinate system based on the spatial reference coordinate system of the best-ranked layer, and no additional operation is performed on the data with the missing coordinate system.

[0015] Furthermore, the input geological map generation instruction is used to identify the intent of the input instruction based on a large language model, the instruction is mapped to a geological map generation tool, the call of the geological map generation tool is post-processed and verified, and the geological map generation tool is executed in sequence to generate a geological map, including the following steps: The interactive interface provides a text input box for geological map generation instructions; it also provides some parameter selectors that are not suitable for text interaction to increase the ease of use of the software (such as base map enumeration items, rendering color levels, etc.); Entering a geological map generation instruction in the text input box and specifying relevant parameters, wherein the relevant parameters include rendering color levels, and the content of the instruction has semantic relevance to the name, description and parameters of the geological map generation tool; Combining the name, description and parameters of the geological map generation tool and the geological map generation instruction, constructing a text generation prompt word of the large model; The large model text generation service is called through the text generation prompt word to obtain the calling result of the geological map generation tool, and the calling result includes the name and parameter value of the calling tool; Post-process the verification results. If a tool name that is not in the defined tool library appears, the tool call record will be discarded; if the parameter type and quantity do not match, the record will be discarded; if the parameter value exceeds the defined upper and lower bounds, the boundary value will be taken; Run the geological map generation tools in sequence for the post-processing results, and define a message list to store the tool execution message of each geological map generation tool. After the execution is completed, save the geological map image; The saved geological map images and tool execution message queue are presented in the interactive interface; Perform the above steps multiple times in sequence until the user is satisfied with the results.

[0016] Furthermore, the text generation prompt is specifically: You are a geological mapping expert who is good at generating maps using vector or raster data and can flexibly adjust the base map; You need to select the appropriate tool based on the tool name and description provided; Please assist and respond to humans as accurately as possible; The following tools can be used: {tools}; The meanings of some of the words in the prompt words are as follows: tools: Fill in the names, descriptions and parameters of all geological map generation tools, expressed in a hierarchical manner in JSON format, with tools separated by line breaks.

[0017] Furthermore, the exported geological map supports multiple data formats, including: Define the geological map export formats supported by the system, including GIS software engineering files, image files, and pdf raster / vector files; According to the requirements, determine the export format, resolution, size and other parameters, export the data of the geological map generation results, and store them in the user's local file system.

[0018] The present invention also provides a geological map generation system based on a large model agent, comprising the following modules: Map initialization module: including data uploading, verification, loading and preliminary rendering functions in the integrated geological map generation method; User interaction module: including command understanding, tool mapping, tool calling and execution result return functions in the integrated geological map generation method; Map preview and export module: includes the geological map export function in the geological map generation method.

[0019] Furthermore, the functions of the module are specifically as follows: After the user uploads the geological map element file, the map initialization module will perform content verification and spatial consistency verification on the supported data types, confirm the visual sorting of the data, and then perform initialization rendering of the geological map according to the template; After receiving the geological map generation instruction input by the user, the user interaction module will perform intent recognition on the input instruction based on the large language model, realize the mapping between the instruction and the geological map generation tool, perform post-processing verification on the call of the geological map generation tool, and then execute the geological map generation tool in sequence to generate a geological map; The map preview and export module provides and displays a default map template before the user uploads the geological map element file, and updates the map after each round of dialogue. After completing the map modification, the user can export the map into a specified data format.

[0020] The beneficial effects of the present invention are as follows: the present invention designs a method and system for efficiently generating geological maps by converting the traditional software mapping process into geological map generation instructions through natural language interaction with a large model. The geological map generation result obtained by this method meets the user's instruction intention and strictly follows the mapping process specifications defined by the system. It is easy to use and has stable product quality. Relying on large model proxy technology, the geological map production process is simplified through text interaction, thereby significantly improving mapping efficiency. The present invention not only promotes the close integration of geological engineering and artificial intelligence technology, but also provides strong technical support for the widespread application and popularization of geological maps.

If it is called incorrectly, it records the specific error information. Figure 2 andFigure 3 As shown, the system returns a conclusion of success or failure for each tool call.

[0032] 1.2.2. Construct an accurate and concise description of the generation tools and parameters so that the big model can better understand the relationship between the user's natural language expression and the generation tools.

[0033] 2. The user uploads the geological map element file and initializes the geological map. Figure 2 shown.

[0034] 2.1. Upload data. The uploaded data in this example includes a surface type feature in shapefile format and a line type feature in shapefile format. The data content is verified. The data verification in this example passes.

[0035] 2.2. Sort the uploaded data and check its spatial consistency: the layer sorting result is "line layer - surface layer", and then check the data's spatial consistency: in this case, the spatial reference coordinate system of all data is consistent, so no additional operation is required.

[0036] 2.3. Provide a geological map drawing template. In this example, select "Template 1" as the drawing template for this geological map.

[0037] 2.4. Loading and initial rendering of uploaded data: In the system, on a blank mapping template, according to the data display order determined in (2.2), load the data in reverse order, and use a simple rendering method to render the data initially: use a random single color for rendering the line and surface layers.

[0038] 2.5. Initialization of map elements: According to the spatial scope of the loaded data content, initialize and adjust the map elements, including the direction of the compass, the expression value of the scale, the viewport range of the main map, the range of longitude and latitude lines, the content of the legend, etc.

[0039] 2.6. After the above operations are completed, the map will be presented on the interactive page of the system.

[0040] 3. Based on the large language model, the intent of the input geological map generation instructions is recognized, the instructions are mapped with the geological map generation tools, and the geological map generation tools are executed in sequence to generate geological map pieces.

[0041] 3.1. The interactive interface provides a text input box for geological map generation instructions; at the same time, in order to increase the ease of use of the software, some parameter selectors that are not suitable for text interaction are optionally provided (such as enumeration items of base maps, rendering color levels, etc.).

[0042] 3.2. Enter the geological map generation command in the text input box and specify the relevant parameters as follows: I want to set the background map as satellite map, and set zoom scale to 1.2.

[0043] 3.3. Combined with the name, description and parameters of the geological map generation tool in step 1 of this example, the text generation prompt words of the large model are constructed through the above generation instructions, as shown below:

[0044] The meanings of some of the words in the prompt words are as follows: tools: fill in the names, descriptions and parameters of all geological map generation tools, expressed in layers in JSON format, with line breaks separating the tools; tools_name: Fill in the names of all geological map generation tools, separated by commas; input: Fill in the input geological map generation instructions.

[0045] 3.4. Generate prompt words through the obtained text, call the large model text generation service, and obtain the calling result of the geological map generation tool, including the name and parameter value of the calling tool.

[0046] 3.5. Post-process the verification results: The results in this example meet the tool call requirements, and post-processing is not called under special circumstances.

[0047] 3.6. For the post-processing results, run the geological map generation tools in sequence, and define a message list to store the tool execution message (Message) of each geological map generation tool. After the execution is completed, save the geological map image.

[0048] 3.7. The saved geological map images and the tool execution message queue are presented in the interactive interface.

[0049] 3.8. In this example, the above steps 3.1 to 3.7 are executed multiple times, and the adjustments include layer rendering, latitude and longitude line styles, legend names, figure names and annotation information, such as Figure 3 shown.

[0050] 4. Export geological maps: Records the long history of Ireland's bedrock geology from the Paleozoic to the Cenozoic. The geology of the region is mainly composed of ancient metamorphic rocks, sedimentary rocks and igneous rocks. During the Caledonian Fold Belt, a large amount of schist, gneiss and granite were formed, which formed the mountains in northern and central Ireland. The southern region is dominated by Paleozoic sedimentary rocks, including Devonian red sandstone and Carboniferous limestone. In addition, there are some important faults in Ireland, such as the Mourne Fault in Northern Ireland, which not only affect the surface landforms, but also have an important impact on the underground structure.

[0051] 4.1. This example confirms that the export format is an image file format.

[0052] 4.2. Determine the export format as PNG, the resolution as 100dpi, and the image size is adaptively adjusted according to the resolution (in this case, 2339 pixels x 1654 pixels). Export the data of the geological map generation results and store them in the user's local file system. Example

[0057] In order to facilitate the scheduling of the above tools in large models, the output type of all tool functions is unified, which is a tool execution message of string type. The execution message records whether the function is called correctly. If it is called correctly, it records the text indicating that the function is successfully called. If the call is wrong, it records the specific error information.

[0058] 1.2.2. Construct an accurate and concise description of the generation tools and parameters so that the big model can better understand the relationship between the user's natural language expression and the generation tools.

[0059] 2. The user uploads the geological map element file to initialize the geological map.

[0061] 2.2. Sort the uploaded data and perform spatial consistency check: The layer sorting result is "line layer-surface layer-raster layer", and then perform spatial consistency check on the data: In this example, the raster layer is inconsistent with the spatial reference coordinate system of the above two layers, so the coordinate system is converted.

[0062] 2.3. Provide a geological map drawing template. In this example, select "Template 2" as the drawing template for this geological map.

[0063] 2.4. Load and initially render the uploaded data: In the system, load the data in reverse order on a blank mapping template according to the data display order determined in (2.2), and use a simple rendering method to initially render the data: use a random single color for rendering the line and surface layers, and perform grayscale stretching rendering of the maximum and minimum values ​​for the raster layers.

[0064] 2.5. Initialization of map elements: According to the spatial scope of the loaded data content, initialize and adjust the map elements, including the direction of the compass, the expression value of the scale, the viewport range of the main map, the range of longitude and latitude lines, the content of the legend, etc.

[0065] 2.6. After the above operations are completed, the map will be presented on the interactive page of the system.

[0066] 3. Based on the large language model, the intent of the input geological map generation instructions is recognized, the instructions are mapped with the geological map generation tools, and the geological map generation tools are executed in sequence to generate geological map pieces.

[0067] 3.1. The interactive interface provides a text input box for geological map generation instructions; at the same time, in order to increase the ease of use of the software, some parameter selectors that are not suitable for text interaction are optionally provided (such as enumeration items of base maps, rendering color levels, etc.).

[0068] 3.2. Enter the geological map generation command in the text input box and specify the relevant parameters as follows: Please do not show the base map, just set the background to lightgray, and set zoom scale to 1.1. 3.3. Combined with the name, description and parameters of the geological map generation tool in step 1 of this example, the text generation prompt words of the large model are constructed through the above generation instructions.

[0069] 3.4. Generate prompt words through the obtained text, call the large model text generation service, and obtain the calling result of the geological map generation tool, including the name and parameter value of the calling tool.

[0070] 3.5. Post-process the verification results: The results in this example meet the tool call requirements, and post-processing is not called under special circumstances.

[0071] 3.6. For the post-processing results, run the geological map generation tools in sequence, and define a message list to store the tool execution message (Message) of each geological map generation tool. After the execution is completed, save the geological map image.

[0072] 3.7. The saved geological map images and the tool execution message queue are presented in the interactive interface.

[0073] 3.8. This example executes the above steps 3.1 to 3.7 multiple times, and the adjustments include line layer color / line width / style, surface layer color / annotation, raster layer stretching color band / rendering mode, longitude and latitude interval / line width, legend name / font size, figure name content / font / color, annotation content / font information, scale unit, and compass size / style.

[0074] 4. Export geological maps: 4.1. This example confirms that the export format is pdf vector file format.
