Description

Technical Field

[0001] This invention relates to the field of application software technology, and in particular to an application method for a natural resources and planning data application APP. Background Technology

[0002] As the informatization of natural resources continues to deepen, the application of natural resource and planning data based on the "cloud + terminal" model has become very mature. However, it mostly operates in private cloud environments built by government departments. Furthermore, due to the special nature of natural resource and planning data, to ensure geospatial information security, most of the data cannot be viewed and analyzed on the internet, leaving scenarios such as user field surveys, on-site inspections, and on-site command and dispatch lacking data support. Currently, in this scenario, firstly, the use of natural resource and spatial data is mostly presented in the form of maps, which suffers from complex production processes and low practicality; secondly, mobile apps are used to obtain small-scale data screenshots and some statistical information through internal and external network interaction technology. This method solves the shortcomings of paper maps to some extent, but it also has drawbacks such as the inability to infinitely zoom in on thematic maps, the need for linkage between massive graphics and attributes, the secure use of sensitive data, and slow data loading speeds.

[0003] Under the existing geospatial data protection system, there are still significant challenges in quickly browsing and efficiently analyzing massive amounts of classified or sensitive natural resource and planning data outdoors. Therefore, it is necessary to propose new technical solutions to compensate for, improve, and perfect the existing data application models and technologies. Summary of the Invention

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Figure 1 The method flowchart provided in the embodiments of the present invention is as follows: Figure 1 As shown, this invention provides an application method for a natural resources and planning data application APP, including:

[0028] Step 100: Collect natural resources and planning data;

[0029] Step 200: Map the time-synchronized natural resources and planning data to generate an MXD file;

[0030] Step 300: Use data processing tools to generate a gpkg database file from the display object layer;

[0031] Step 400: Based on the mxd file, use a tiling tool to generate mbtiles raster tile data;

[0032] Step 500: Write location information to the gpkg database file;

[0035] Preferably, the natural resources and planning data are vector data with spatial location information.

[0036] Preferably, the data processing tool is a database format conversion tool.

[0037] Preferably, the slicing tool is a software tool for converting vector data into raster data.

[0038] like Figure 2 As shown, the specific steps in applying this embodiment include:

[0039] Step a: Natural Resources and Planning Data Collection

[0040] In this example, the data processing personnel collected and organized the relevant data according to the local coordinate system and named it in a standardized manner.

[0041] Step b1: Map the natural resources and planning data to generate an MXD file.

[0042] After the data collection was completed, the data processing personnel used ArcGIS software to process the natural resources and planning data into SHP format data, then completed the mapping and saved it as an MXD format file.

[0043] Step b2: Use data processing tools to generate a gpkg database file from the display object layer.

[0044] In this example, the layer file whose attribute information needs to be displayed is selected in the natural resources and planning data. Then, the data processing tool is used to process the display object layer to generate a gpkg database file, thus realizing the attribute query function.

[0045] Step c1. Use the tiling tool to generate mbtiles raster tile data.

[0046] Import the MXD file saved in step b1 into the self-developed tiling tool, fill in the layer name, data type and other information, and then export the mbtiles raster tile data to improve data security and optimize data loading speed.

[0047] Step c2. Write location information to the gpkg database file.

[0048] In the data processing tool, the same location information as the corresponding natural resources and planning data is written into the gpkg database file to achieve matching of attribute information with vector data.

[0049] d. Use the settings function of the Natural Resources and Planning Data Application APP to associate mbtiles raster tile data with the gpkg database.

[0050] In the settings of the Natural Resources and Planning Data Application APP, the mbtiles raster tile data path is linked to the gpkg database file to achieve linked display of map attributes.

[0051] e. The Natural Resources and Planning Data Application APP reads data, displays maps using mbtiles raster tiles, and queries the gpkg database to enable attribute browsing.

[0052] In this example, after the data information is connected, the Natural Resources and Planning Data Application APP reads the mbtiles raster tiles and gpkg database files from the two paths, and finally displays the map and attribute browsing on the display interface.

[0053] This embodiment utilizes efficient offline data storage technologies, such as data preprocessing, data index construction, and offline data compression package construction, to solve the problem of offline storage of massive amounts of data.

[0054] The software fully integrates CPU computing power at the underlying level, uses parallel computing for data computation, and calls GPU to assist in computing, achieving a response time of seconds in data application analysis and attribute query and location of tens of millions of map patches.

[0055] This embodiment provides vector data offline tile technology for vector data visualization, including a complete set of vector hierarchical indexing and rendering technology systems, including vector hierarchical slicing index, high-speed data cutting, and efficient rendering technology, to achieve efficient browsing and real-time querying of a set of data across large, medium and small scale ranges.

[0056] The beneficial effects of this invention are as follows:

[0057] This invention addresses the challenges that traditional apps cannot solve, such as massive image and attribute linkage, secure use of sensitive data, and slow data loading speeds. Compared to traditional apps using data formats like shapefiles, gdb, and kml, this invention significantly improves the speed of data display, patch attribute querying and location, and data application analysis, while providing a stable and secure environment for sensitive data. It enhances the user experience by accelerating data display. Through a combination of efficient map tiling encryption technology and offline use, it ensures the security of natural resource and planning data. In terms of application performance, a single map file can display an area exceeding 200,000 square kilometers, with a 1-second response time for browsing from a global perspective to the smallest patch, and a 1-second response time for querying attributes of 15 million patches.

Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope.
