Net adjustment contents


Net adjustment

Topocad Net adjustment is based on calculations using the Least Squares Method, and a number of functions have been created for this to bring in data in appropriate ways and as methods for searching for errors. There are also a range of functions to customize the appearance of the results you want to present.

Entry data is based on a purge having been made to Topocad's survey data file using the SUR file format, and this data is then imported to the net adjustment; but entering data directly to the net adjustment measurements works equally well.

The known points are loaded from the preset polygon point file (default is Topocad.PP) but you can also enter known coordinates under the New Points tab.
