Coordinate Reference Systems defined by ESRI Projection file
CRS Uses PRJ Files

GIS .prj Files

Sneak Peek (1:48)

TPC can now use GIS .prj files as the Coordinate Reference System for your survey.

Just select a .prj file and TPC will evaluate it to see if it contains the CRS information. If it does, you can use it to define your CRS.


Sneak Peek (2:44)

Now you can access projection sources, like SpatialReference.org, to find the projection you need. Export it as an ESRI prj file and you can use it in TPC.


Geodetic Computations with Local Grid

CRS required for geodetic computations
CRS Distance Type Mismatch

We added a new warning when you try to compute geodetics with a local grid.

In this situation, of course, nothing gets computed, because there isn’t a projection. The new warning explains why it works that way.




Min / Max Surface Contours

Sneak Peek (1:28)

You can now specify Minimum and Maximum elevations for contours. This lets you specify a single elevation for a FEMA elevation or restrict the contours to any elevation range.

Sort Drawing Layers
Sort Layers by Drawing Order

Sort Layers By Drawing Order

In the Drawing View, the Layers Dialog now includes an option to sort layers by their order in the drawing instead of alphabetically.

Drawing Data Manager

Convert to Survey from Drawing Data Manager

Here is another way to convert CAD objects to survey data. Just select the object you want, right-click and choose Convert to Survey.

Be sure to delineate the object in the drawing to make sure you have the right object.

Drag and Drop

Drag and drop layers / entities to change their drawing order or move entities between layers.


XRefs Store Reference to Survey

Once you reference an XRef to your survey, TPC stores the reference parameters (translate, rotate, scale) with the XRef so you can reload the XRef without re-referencing it to the survey.

XRef Data in Drawing Data Managers

XReference CAD
XReference Information

TPC now includes XRef information in the Drawing Data Manager. Just expand the XReference and you’ll find it’s filename, number of objects, scale and rotation, etc.

Missing / Renamed Xref Files

Missing XReference
Missing XRef

If an Xref used by a drawing is not available or has been renamed, you can use the View, Display Missing Blocks/Pictures command to display its stored pathname. You will see something like {C:\Data\Drawing1.dwg}.

To locate and update the XRef filename or location, double-click the bracket text or right-click it and choose Properties. TPC opens the XReference dialog where you can Browse to the location of the XRef file.


Trimble DC7

We’ve added support for additional records in Trimble DC7 and DC10 files.

  • B6 Long Feature Code
    • these become the attribute of the current point
  • 70 Ground Vector
    • We had been ignoring these if the From point label did not match current OP
    • We now add and OP and FS all the time
    • az,hd,vd from reference point to foresight
  • 67 GPS Vector
    • these are delta X,Y,Z in ECEF coordinates.
    • TPC now uses ecef / lla computations and delta x/y/z for the antennas to compute the vectors
  • A0 – Stakeout Point Design
    • part of 67, A0, A5 sequence
    • lists the design point being staked and the stakeout method
  • A5 – Point Grid Deltas
    • x/y/z offsets of point actually staked and measured are stored as raw data
    • offsets are measured to design
  • C6 – Quality Control 1
    • PDOP, HDOP, VDOP, etc.

Import Details

If the Message View is open and you import data with the [x] Details option turned on, TPC imports up to 4X faster by grouping lines before updating the

Message View

Imported survey points
Import Summary Includes Points

TPC also adds a [Summary] section to the end of the details in the Message View and displays the total number of points imported.



Manage Your Own Licenses

You can now manage your own licenses on-line 24/7.

  • Need to move your license to another computer?
  • Did your old computer die and you need to install TPC on the new one?
  • Want to go back and re-install an older version of TPC?
  • Want to work on a second computer at home or in the field?

You can do all these and more with our on-line license manager.

User Forum

We’ve added a user forum to our web site. Once you’ve registered, you can log in and access the forum 24/7.

Sharing Technical Support Responses

We are moving much of our technical support to the forum so the help we provide on a particular topic can be used by others who access the forum.

Plus, other TPC users can jump in and answer, providing more ways to tackle a workflow.

Better Searching

Just type in what you know and TPC will list all the topics that match.

Want to know about surface exclusions? Just type in ‘exclusions’ or ‘surface exclusions’ or even just ‘surface’. The look through the topics titles and select the ones that match.

Resolved Issues

Once we’ve answered your question, the topic is marked as Resolved. As you search, you’ll find yourself looking for topics that match and also say Resolved. That’s where you can jump in and look at the answer.
