Added a point, road/polyline, and area/polygon drawing toolset. All items have handles which can be selected and dragged, similar to ArcGis, only less sophistated. Dropdown box allows picking of named points (lets call them cities). Selecting a city, centers the map to the appropraite point/city.
Roads are drawn when zoomed, but are collapsed (not-visible) when zoomed out. Have a simplistic load/save feature for all vector items. A default vector item list is preloaded at application startup. Silverlight makes saving awkward and I haven’t figured out how to make a data web service on a unix server yet.
My working prototype is available.
