There are tools like MapWindow GIS
that support creation of shapefiles, but creating such geo-imagery is by no means a simple task so we would suggest you to either look for some useful ready-made solutions under Creative Commons licensing (e.g. http://www.geocommons.com
), or check what a commercial GIS vendor like ArcGIS
can offer in terms of available shapefiles. Map shape layers support only ESRI shapefile format.
As for your second question, you have to specify the coordinates of each user defined shape - here is an article that explains how the coordinates are interpreted. As you can see in the attached project, the ChartMapDataItem inherits from the MapDataItem class, that exposes Location property.
I hope this helps.
