Model
The model is a graphical representation of a series of Data Processing tools, which visually represents all the tools (functions) in Geo-Processing Automation (GPA) modeling, as well as the corresponding connections.
Toolbox
The toolbox provides 1000 + geographic Data Processing and analysis tools. Including Data Import, Data Export, Data Processing, Spatial Analysis, Spatial Statistical Analysis, Online Analysis, etc. The Python Custom Tool is also supported.
- Search: The toolbox provides a search function, and users can search related functions through Keywords. Understanding the specific use of these tools can better help us build models.
- Predefine Model: provides two predefine models, Dynamic Segmentation and Hydrological Analysis, which can be opened and viewed by double-clicking the model node.
Elements of the model
- Tools
Tools are the basic building elements of the model. A tool includes a tool node and a variable node, as shown in the following figure. The Rounded Rectangle part is the tool node, and the oval part is the variable node.
- Tool Node: Refers to the body of Parameter Settings, in which the source data parameter, function parameter and Result Parameter can be set.
- Variable Node: It can represent the Result Data of the current tool, and can also be used as the source data of the next tool.
- Parameter: click the tool node to set the corresponding source data parameter, function parameter and Result parameter in the parameter panel.
Note: Result Parameter cannot be set for the variable node.
- Connector
- Linking refers to establishing logical relationships and passing parameters between tools in the model.
- The parameter relationship refers to the result output data of the previous function as the Input Data: of the next function. When connecting, you can select the type of Input Data:, as shown in the following figure. The Buffer Zone Analysis result can be set as the source data intersected by Overlay Analysis or Overlay Data.
- A logical relationship means that the next function is performed after the previous function is performed. Select Pre-condition when connecting, as shown in the following figure. First, iteratively delete Text Dataset, and then convert Line Dataset in Datasource to Region Dataset.
- Select the connector to modify the line form, including straight line, Elbow Polyline and Relation Connection, as shown in the following figure:
