Coordinate traverse
Station, backsight, site points and closing point. Open or closed. Bowditch, Transit or Equal adjustment with precision 1 : N.
Professional
Traverse andLevel Adjustment Software
Precision in every point
Enter the coordinates you measure on site, close on a known point and get an adjusted, checked result with a signed PDF report. Level books are reduced, checked and adjusted the same way.

Everything the field team needs and nothing it doesn't
Levelling
Rise & Fall or Height of Instrument. Arithmetic checks, misclosure against your allowable, adjusted RLs.
Traverse simulator
Watch a total station observe a traverse with real instrument errors, then adjust the result. Ideal for training.
Your dashboard
Every traverse and level run you save is kept in your account, ready to open, copy or share.
Share with your team
Share a job with a checker or client by email. They see it in their own dashboard.
PDF reports
Input and output coordinates, closure check, bearings, sketch and signature boxes on every report.

Example result from the built-in sample traverse.
Know in a second if the traverse closes
Green means accepted, red means re-check the field data. Corrections, adjusted coordinates, bearings and distances are listed point by point, exactly as they appear in the PDF report.

Training
Traverse simulator
A total station observes a traverse with realistic random errors, carrying the bearing forward by backsighting each station. Then adjust the result in the Traverse tool.
