Mapping Errors |
We all know that no mapping system exists that is correct in all areas. The correct position was located using Google Maps and based on the aerial photos. Shown is the common position of most mapping systems. The address we were looking at was 110 Dylans Ct., Covington, GA 30014, located at Lat-Long 33.53357, -83.84741. This just happened to be the first place I click on from the FieldRepPro program, other addresses in the area were also correct.
FieldRepPro uses Area Entry Locations and Major Intersections to help fight these problems with mapping errors. FieldRepPro uses up to two Area Entry Locations which have up to three Major Intersections associated to them. FieldRepPro uses MapPoint at least gets you close if not on the mark, then you can view in Google and center the correct location and retrieve the Latitude and Longitude for that location with a simple script.

DeLorme Earthmate GPS (Bad Wrong)
This one really missed the boat. Dylan Downs Blvd??? But at least you can correct the problem with the ability to add roads. This is a real plus for areas under development.

OpenStreetMap.org (Real Close)
This one looks real close to how it is, at least it will get you there.

MapWindow GIS with US-Census TIGER shapefiles (Correct)
This is all correct and so are some of the other areas that are bad wrong or missing. But the shapefiles contain allot more geographic features.
Note: MapWindow GIS is a free desktop geographic information system (GIS) application with an extensible plug-in architecture. This application does not provide any turn by turn directions, just good mapping.
