Person who carried out this activity:
Positional accuracy was determined by solution of Socet Set generated model (RMS less than 1) and by comparison to independent ground control data.
0.1 +- 3.0, y=0.9 +- 4.4 (values are in meters +/- standard deviation)
Data is complete.
These data are believed to be logically consistent, although not tested. Geometry appears topologically clean.
Are there legal restrictions on access or use of the data?
