Traverse PC Land Surveying Software Featured VideoUsing the Drawing View (4:24) Do COGO right from a drawing using selected drawing objects.

This video shows you how you can work with the COGO tools in Traverse PC and pick the survey points and lines graphically from the Drawing View. You can manually fill in the fields in the COGO dialog boxes, use equations to enter data or click in the Drawing View to get the results you need. It couldn’t be easier.

Demonstrates typical BLM work flow using TPC.

These videos were developed for a BLM Training Session 3-26-2012. They use BLM job, G2346 to walk through common everyday tasks using TPC Desktop. They are also intended to be a general reference to using TPC Desktop for the PLSS.

Step 1. Download the outlinemap and sample files

Step 2. Watch a video

Importing CMM geodetic points - import geodetic points exported from CMM’s COGO list

Entering geodetic control points - enter geodetic points directly into TPC, either in the Points manager or the Traverse View

Establishing basis of bearing - use imported geodetic points for your occupied station and backsight or enter a solar observations for a reference azimuth

Cleaning up raw data - learn how TPC stores raw data from your data collector and how to edit it in the Traverse View

Intermediate least squares check - use LS to check your field data without updating the survey points

Importing field data 2 - this alternate method for import field data creates observations (OBS) to control points you tie in the field so you’re all set up for a Least Squares analysis

Creating individual control loops - if you want, you can separate out control loops that were imported from one main raw data file or you can import separate raw files for each loop

Adding a retrace traverse - TPC uses a retrace traverse to store your existing (found) corners for PLSS computations and to start your true line diagram and final plat

Adding a record traverse - store the GLO calls in a record traverse then use them in PLSS computations for lost corners. Learn how to enter GLO data in chains for feet.

Mixing record data and existing points - as you find corners/monuments, insert them into the record traverse and recompute record positions from the found corners to improve your searches

Finding points - learn how to find points, drill down through points piled on top of each other in a drawing, do a one-step zoom toggle to create separation and window extents

Creating a ‘search area’ traverse - create a plot, printouts and reports to help you search for corners and accessories

Exporting coordinates - send State Plane coordinate points back to your data collector

Exporting geodetics - send geodetic positions out to an ASCII file

Computing double proportion - use retrace and record traverses to make this so easy

Creating corner moves - generate corner move (stakeout) notes with alternate backsights
