TPC Desktop Personal Edition is a feature packed survey program. It offers the Basic COGO, Basic Drawing Tools, Basic Traverse Adjustments, Custom Reports and Import/Export tools you’ll use every day. You’ll find support for most popular data collectors and total stations along with our Traverse View data entry and Points Manager data base.

The menus and tool bars have been streamlined to make TPC Desktop Personal easy to learn and use. You can learn how to use the tool bars and context menus as you go and then move up to the Premium Edition when you need more muscle.


  • Coordinate Conversion: Convert coordinates between feet, meters, chains and custom scale factors.
  • Grid vs Ground: Convert between Grid and Ground coordinates.

Coordinate Reference Systems (CRS)


  • Import / Export: User-defined import and export of point data along with conversions with specific other formats
  • Point Properties: Draw points with settings for symbols, labels, layers and style
  • Alpha/numeric: Alpha numeric point labels
  • Point Protection: Lock coordinates, elevations and descriptions


  • Traverse Formats: Format the Traverse View the way you want
  • Traverse Groups: Traverse groups help you organize survey data on the fly
  • Traverse Manager: Copy and duplicate existing traverses or create new ones
  • Traverse Settings: Let TPC draw the map for you using our Quick View™ technology
  • Angle Sets: Use both direct and repeat angle methods
  • Raw Data: TPC retains the data you enter even after an adjustment – just recompute any time
  • Closure: One-step closure check, automatic closure
  • Elevations: Use benchmarks, +/- target heights and any combination of vertical angles, offsets and stadia
  • Automatic COGO: The things you do all the time, like extending a line, inserting a mid-point, entering a horizontal curve happen almost without thinking about it
  • Shared Boundaries: Recall points from any other traverse to share a common line
  • Remote Observations: Shoot as close as you can get and enter perpendicular, linear, angular or vertical offsets
  • Insert Points: Insert points by point label range, proximity, description, etc.


  • Standards: All your favorites like intersect, rotate and translate and random inverse.
  • Corner Offsets: One-step offsets for building corners
  • Lot Setbacks: One-step lot setbacks
  • Offsets to Line or Curve: Compute the cardinal or perpendicular offset of any point to a line or curve
  • Multiple Points: One-step fill in points along a curb line with interpolated elevations
  • Visible COGO: Instantly plot any COGO point then watch it update automatically as you adjust the COGO data
  • Multi-level Undo: Create new COGO points or update existing points and if it doesn’t do what you want – Undo it.
  • Equation Parsing: Enter 10..11/2 to recall half the distance from point 10 to 11 or enter 10..11+90 to recall the bearing from point 10 to 11 and add 90° to it. No need for a calculator here
  • Spacebar: Recall the previous direction or distance by pressing the spacebar
  • Summary Button: Add COGO results to a report for a record of what you did then add your own notes
  • COGO Graphics: One button generates a drawing showing the COGO results so you pick the points you want
  • Predictive Data: Start typing the point label and TPC displays matching points so you can pick the one you want
  • Graphical Selection: Pick points and lines directly from any drawing and TPC fills in the COGO data


  • Import / Export points and traverses as shapes: Traverses correlate directly with shapes.
  • Export drawings as shapes: The drawing determines which traverses get exported plus all your other drawing objects.
  • Export data: Include point coordinates in descriptions in the separate DBF file
  • Import / Export geodetic: Choose between latitude/longitude and coordinates.

Roads / Alignments

  • Horizontal Curves: Create curves from any data
  • Spiral Curves: Enter any combination of tangents, spirals (balanced or unbalanced) and curves
  • Cul-de-sacs: Enter cul-de-sacs even with delta >180°
  • PI Tangents: PI curves / spirals insert alignment points and update on the fly
  • Stations: Insert stations / equations along any alignment
  • Stations / Offsets: Locate and stakeout points by station / offset just like you do with coordinates
  • Centerline Offsets: Create centerline offsets
  • Curve Fitting: Computes best-fit radius
  • Multiple Points on Grade: Creates points along a grade at specific intervals (every 2′, 5′, etc.)
  • Find Station / Offset: Find the station / offset of any point to any alignment
  • Drawing Labels: Label curves, spirals and tangents the way you want


  • Coordinates: Choose from Compass, Transit or Crandall methods and/or Balance Angles
  • Precision: Recompute any traverse, closure and area based on separate distance and direction precisions
  • Factors: Expand or contract each course by a distance factor.
  • Undo: Undo any adjustment and start over
  • Adjustment Details: Report the adjustment for each point

CAD View

Open any DWG, DGN or DXF file.

  • Pan & Zoom: Pan and zoom to get to the part of the project you are working on
  • List: Select entities from the CAD drawing and List them to a report or right-click and choose Properties to see their data
  • Send Objects: Send CAD entities to TPC’s current drawing or objects from the current drawing back to the CAD view (Professional Edition only). This is such a


  • Data Collectors: Import / Export from all the popular data collectors, total stations and GPS
  • Coordinates: Import / Export coordinates and geodetic positions
  • Raw Data: Import / Export raw data CSV files
  • CAD: Import any DWG or DXF file
  • PDF: Save any drawing or report as a PDF
  • Pictures: Import background photos or vicinity maps in JPG, TIF, GIF, BMP, ICO, PNG, etc.
  • Shape Files: Import / Export shapes
  • Direct Connection: Import / Export files or connect directly to device


  • Templates: Save any drawing as a template or choose one that ships with TPC
  • Drawing Manager: Organize your drawings in groups, just like traverses
  • Page Layout: You always work on a sheet of paper
  • Associative Data: Data association isn’t an after-thought in TPC because the drawings are built from the data
  • Geodetic Drawings: Use geodetic distance, direction and area for all drawing labels

Quick View™ Technology

  • Traverse Settings: They do 90% of a drawing for you
  • Surface Settings: Choose the line types, colors, symbols and layers you want for each surface
