Geo-Processing Automation (GPA) refers to a series of Geographic Data Processing tools, which are connected through a certain logical relationship to build a model that can be automatically processed. The Geo-Processing Automation (GPA) model is a flow chart of a series of Geographic Data Processing tools concatenated together, where the output of the former tool is the input of the latter tool.
Tools in the model can be sourced from the toolbox or customized through Python. The toolbox provides rich geographic Data Processing and analysis tools, including Data Import, Data Processing, Spatial Analysis and other functions. It can be used to automatically manage and analyze GIS data.
When Create New Model, you can drag the tools in the toolbox to the canvas and connect them logically according to the functions you need to implement. All Functions in the Model tool can be completed automatically at runtime by simply entering the relevant Dataset.
The top of the Geo-Processing Automation (GPA) modeling page is the menu bar, the left side is the Workspace, the middle is the Model Builder canvas, and the right side can be flexibly switched between the Parameter panel and the toolbox. The overall interface is as follows:
Main functions
The main functions supported by Geo-Processing Automation (GPA) are as follows:
- Modeling: The Geo-Processing Automation (GPA) window supports tools to add, delete, select, connect, move, zoom, etc.
- Check whether the workflow you created has not filled in the required parameters.
- Run: Run a single model node, or execute the entire model and Task Manage the executable process.
- Coverage Result: Check Coverage Result in the top menu bar to overwrite the Result Data of the same name when executing the model. It is supported to overwrite Dataset and Local File in Datasource. It should be noted that some tools do not support the overwrite operation yet. When there is Result Data with the same name, the Failed to execute or the suffix will be added to the Resulting dataset name for Renames.
- Save: The constructed workflow can be saved to Workspace or Save As Tool, which is convenient for subsequent reuse or modification of operation steps and parameters in the workflow.
- Share:
- Local: export the built model as Model File, and share the workflow conveniently by loading the Model File.
- Publish: Publish the built model to the iServer service, edit and manage the model on the Web side, and facilitate the running of the model in the server.
Main features
- Tools are rich and customized: about 900 kinds of tools are provided in the toolbox. Including Data Import, Export, Data Conversion, Data Processing, Spatial Analysis, Spatial Statistical Analysis, Online Analysis and other tools.
- No need for programming, easy to operate: no need for programming basis, easy to operate through the addition, movement and connection of tools in the model, and realize the functions of data import, management and analysis.
- One-click execution, unattended: After the model runs, the tools in the model can be automatically executed in turn according to the order.
- Convenient loading and output of templates: Geo-Processing Automation (GPA) models can be exported as model *.xml files, and can also be published to iServer services to achieve multi-terminal sharing and use.
Examples
The application example in the figure below is to extract the wind power isosurface of a certain area according to the data of meteorological stations. The model executes the following tools in sequence:
The model executes the following tools in sequence:
- Import EXCEL: import the wind data of the meteorological station in the study area;
- Dataset Projection Transformation: Defines the coordinate system for the imported wind point data;
- Import SHP: import the contour surface data of the study area;
- Ordinary Kriging interpolation: perform Interpolation Analysis on Point Dataset according to the specified wind field;
- Extract Isolines/Areas: Extract wind isolines and isosurfaces according to the interpolated Raster Data;
- Cutting: cutting the extracted wind power isoline and the contour surface data of the study area;
- Intersection: the extracted wind power isosurface is intersected with the contour surface data of the study area.
