Which shape file is more appropriate for drawing a boundary of an area. I mean would I take polyline feature or polygon feature for drawing a boundary?
I want to digitize a map of metropolitan area. First I have made a manual map and now I am trying to digitize.In this map there are moujas, thanas, rivers, roads, different important location such a market place, police station. So in this case, there is overlapping of borders. Because a thana border can be a district border at the same time. So In this case which feature I chose.
