I am writing a mapserver application that will geocode a street address. I desire to plot a point in the center of the map( that is the street address ) and then draw a concentric circle about the point with a radius of 3 miles. How can I determine the extents of the map so that I can request the appropriate size map? I desire the map itself to be able to show local street names in a city.
You can determine the extent of a shape file using: ogrinfo -al -so file_name.shp but i am not sure if that is what you are asking
