Looking at the GPS Track in the Context of a Variety of GIS Data
A GPS receiver gives position, not location, information. To recognize a location, you need contextual information. You have available, on the DVD, part of which you copied to your personal folder, several digital maps and images of a portion of the Kentucky River plus a couple of vector datasets of a few arcs from two USGS quadrangle maps. The county to the north of the river is Fayette; that to the south is Madison. Of the two USGS 7.5-minute quadrangles that cover the area, the westernmost is COLETOWN; the other is FORD.
