I only need to get RGB values for polygon features. In particular solid fill vegetation and geology. I made a rough as guts ArcPy tool that fits my purpose. The tool gets the user to nominate their layer and symbology field in ArcMap. The tool then loops through groups of "like sybology" values exporting them as rasters and interrogating them for their RGB ...

SQLite does not care about types and VARCHAR and NVARCHAR mean just the same for it http://stackoverflow.com/questions/3930501/difference-between-varchar-nvarchar-in-sqlite.

You will probably need some extra controls as well. Dialog Control PopupMenu Width 200 ID 100 ...

This functionality is currently not available in MapInfo. It's also not available in ArcGIS. See this related post. The ArcGIS Idea linked in that page also doesn't appear to have been implemented. I've also had a look in QGIS, but have not found a way to do it. I did find this feature request for QGIS, but it doesn't look like it's been implemented yet ...

This is a relatively easy process to perform in MapInfo. There isn't a Spatial Join tool in MapInfo, per se. However, you can do the join using the Update Column tool. Note, I'm using 12.5, but the steps are the same in 10.0. I created a polygon table called Polygon and gave it a field called PolyID. I also created a point table called Point and gave ...
