The plans I've seen involved "surveying" 36 townships by setting 2 new control monuments total. There are townships that they would call surveyed that are almost 20 miles to the nearest existing monument. So it's really a stretch to call it a survey. Blm surveying has been done with GPS for sometime now and that is not what this dispute is about. Basically BLM is saying that if they put a coordinate on a map and call it a corner, it's surveyed. Very similar to the protraction diagrams they used in the past except they list coordinates for all interior corners.
