Astrological mapping is a useful and fascinating study. It is important to realize that for there to be appreciable differences in delineation between one location and another, they need to be at least 300 miles apart (as a function of planetary orbs, which extend the area of aspects' influences).
Solar Fire, Matrix, Io (for Mac) and Kepler have wonderful mapping modules. Solar Fire comes with a mini-mapping module they call Solar Maps Lite; the full mapping program is called Solar Maps, which can either stand alone or interface smoothly with Solar Fire.
Of all the mapping programs I've seen, Kepler's (

Kepler comes with several preconfigured options for selecting locations that might benefit specific areas of life like romance, work and family relationships.
