Instructions for use
Creating models involves intelligently connecting multiple professional geographic data processing tools according to preset business logic to form an automated spatial analysis workflow. By programming and pipelining complex geographic data processing procedures, it effectively avoids manual step-by-step operations, significantly improving work efficiency. It is suitable for batch data processing (such as multi-region analysis, periodic data updates, etc.), substantially enhancing productivity.
Operation Instructions
- Open Model Builder: In the Ribbon-style interface, the Model Builder is hidden. You can open it through any of the following entries:

After the model runs, you can view the processed result data in real-time using the preview button on the tool's output port. For traditional canvas style, after running the model, you can open and browse data via the "Add to New Map" option in the variable node's context menu.
