Look at some of the things SurvNET can do!
Carlson SurvNET is Carlson's Network Least Squares Adjustment (NLSA) program. This module performs a least squares adjustment and statistical analysis of a network of raw survey field data, including both total station measurements and GPS vectors. SurvNET simultaneously adjusts a network of interconnected traverses with any amount of redundancy. The raw data can contain any combination of traverse (angle and distance), triangulation (angle only) and trilateration (distance only) measurements, as well as GPS vectors. The raw data does not need to be in any specified order, and individual traverses do not have to be defined using any special codes. All measurements are used in the adjustment.
SurvNET reduces field measurements to State Plane coordinates in either the NAD 83 or NAD 27 coordinate systems. In the 2D/1D model, a grid factor is computed for each individual line during the reduction. The elevation factor is computed for each individual line if there is sufficient elevation data. If the raw data has only 2D data, the user has the option of defining a project elevation to be used to compute the elevation factor.
A full statistical report containing the results of the least squares adjustment is produced and written to the report (.RPT) file. An error report (.ERR) file is created and contains any error messages that are generated during the adjustment.
