There is also an inherited error in the mylar maps. When matching the mylar maps with the BLM land surface management maps, it was difficult to arrange the mylar maps in a way that the fences would be correct in all areas. For example, the mylar map would match accurately in the northeast corner, but would be slightly off in the southwest corner. All lines were given a fence identification number from the mylar maps which they were digitized. Most of these are very small fences covering one square mile or less.
All lines are free of dangles and intersections without nodes.
There are lines with duplicate attributes of the fence identification number. This is due to many fence segments making up one fence. Maps were digitized to a master file. If nodes at the edge of the maps did not snap, they were snapped manually. This data should not be used for defining exact boundaries for ownership or combined with finer scale maps.
