Polygon collections that form a “coverage” are a common form of GIS data. This tool will allow users to edit the locations of boundaries that are shared by two or more polygons.
The tool will allow users to edit un-shared vertices as usual, but where a vertex is shared by a neighboring polygon, the edges of both polygons will be altered simultaneously. In the cases of multi-polygon junctions, the edges of all polygons sharing the vertex will be altered simultaneously.
Tasks:
- Draft a design that can handle the potential performance impacts of needing to test all polygons in the edit area for adjacency.
- Performance test the chosen design and mock-up prototype.
- Complete implementation and test with users for intuitiveness.

CQL is a terse language for writing data filters. This item will allow users to flip between a GUI view of the filter and a text view of the filter in CQL, and edit either one.

New web technology and powerful handheld devices mean that web technology can be used in an “offline mode” using local resources and synchronizing with servers with connections are restored.
