KB10630 - Perform a spatial selection using a shape from another layer.
There are two ways to use a line or polygon to spatially query on a vector layer.
- Manually draw the selection line or polygon using the Select feature supported both the TatukGIS Editor and the free GIS Viewer.
- Use the geometry of a line or polygon shape from a different layer to perform the spatial selection by copying the shape geometry to the Editor clipboard and then using the content of the clipboard layer to perform the selection.
The spatial selection functionality in the Editor is advanced, reflecting the DE-9IM Model for querying based on geometric relations between shapes that is supported in the TatukGIS Developer Kernel product. The DE-9IM Model is explained in detail in the DK Guide.
