Embodiment 1
[0027] Such as figure 1 As shown, this embodiment provides a method for customizing a GIS data processing model, including:
[0028] S101: Receive a user addition instruction, and add a data input node, a result output node, and an analysis node according to the user addition instruction.
[0029] In step S101, the analysis node includes a matching node and a calculation node;
[0030] S102: When adding the analysis node, select one or more of a matching node and an operation node to add.
[0031] S201: The data input node presets several data types, when adding the data input node, receives the user's selection of the data type, and takes the data type selected by the user as the target data type of the data input node .
[0032] In step S201, the data type includes vector data and raster data.
[0033] S202: The result output node presets several result types, when adding the result output node, receives the user's selection of the result type, and takes the result type ...

The invention relates to the field of GIS data processing, in particular to a GIS data processing model customization method. The GIS data processing model customization method comprises the following steps: adding a data input node, a result output node and an analysis node; a plurality of data types are preset for the data input node, when the data input node is added, selection of a user on the data types is received, and the data type selected by the user serves as a target data type of the data input node; a plurality of result types are preset for the result output node, when the result output node is added, selection of a user on the result types is received, and the result type selected by the user serves as a target result type of the result output node; and connecting the added data input node, the result output node and the analysis node to form a GIS data processing model, so that the GIS data processing model is used for processing the GIS data before the GIS data is put in storage, and the construction process of the GIS data processing model is simplified.
Description
technical field [0001] The invention relates to the field of GIS data processing, and more specifically, to a method for customizing a GIS data processing model. Background technique [0002] Before the GIS data is imported into the database, it needs to be analyzed and processed to ensure the unity of the data in the database, and it is convenient for subsequent users to call the GIS data through the database for calculation and research. [0003] The analysis process of GIS data is inseparable from the data analysis model. The traditional data analysis model is generally made by writing codes, which is difficult to make, low in efficiency, low in reusability of the finished model, and difficult in algorithm. increased difficulty. Contents of the invention [0004] The present invention aims to overcome at least one defect (deficiency) of the above-mentioned prior art, and provides a method for customizing a GIS data processing model, which is used for constructing a vis...
