default roads from TIGER files

Posted by RayOnTheFarm on 7 October 2012 in English (English)

Some of the roads, from the older TIGER files, have poor positioning. In some cases the relationships of roads to other roads, is totally wrong when compared to the satellite overheads. It isn't merely a matter of roads being offset, they were poorly defined in the first place.

Currently trying to clean up the eastern half of Dixie county. Using overhead imagery, the more recent 2012 census BAS plots (usually correct, but not always) and the local county property appraiser's online map/parcel display. Some combination of the three usually yields the ground truth.
