With the Survey module, users are able to graphically reduce and edit survey data, apply adjustments and transformations, create and label subdivisional (estate) lots and create upload setout data. The graphical Cadastral traverse spreadsheets are included.

Field feature pickup includes sections, templating, arcs, pipes and culverts
Corrections to field data (typically miscoding) are done interactively on the computer screen and corrections added to the 12d field file. The original observations are always available
Adjustments include Bowditch, Compass, Transit and Least Squares
Transformations and conversions, including WGS84, circuits 1949 and 2000, NZMG, TM2000
