I've been using Locus since Nov. 99, mainly in one area. Everything is referenced to SPC and recently I put all the data into one file. It's about 28 mb of data, contains 4 published NGS horizontal and 6 vertical sites, 210 vectors, 84 repeat vectors (of which 6 failed at settings of .039'+3 ppm H and .066'+3 ppm V at 95%); the network encompasses about 57, 900 acres and the perimeter is about 238,100'. Fully constrained, chi-square passes very near 1.
All observations were static. Anybody else with a monster network using Locus?
