TPC Desktop 2023 R1
TPC and RTK NTRIP
This version introduces tools to use TPC as part of a generic RTK NTRIP solution.
We worked extensively with emlid and their $2,600 Reach RS2+ receiver. We are pleased at how much we could accomplish with this TPC and RTK NTRIP solution.
Pair TPC with your favorite GNSS manufacturer and see how far you can go.
Solution: TPC and emlid RTK NTRIP.
What does the RTK GNSS accuracy test between the Emlid Reach RS2 and Topcon Hiper VR tell us?
GNSS Workflows
We’ve streamlined common GNSS workflows, making it easier to use TPC with your favorite GPS / GNSS equipment.
- importing / exporting GPS / GNSS CSV files
- calibrating GPS/GNSS data to existing surveys
- supporting low cost manufacturers like emlid and Bad Elf
- supporting GPS/GNSS feature codes
GNSS CSV Files
TPC now imports and exports GNSS CSV files like those from emlid and Bad Elf.
There’s even a generic GNSS (CSV), shown here, you can use for any GNSS CSV file.

We’ve added a number of tools to help you move easily convert any survey from one CRS to another.
Convert Survey to GNSS
TPC can convert your local (like 5000/5000) / State Plane / UTM survey to the CRS used by your GPS/GNSS equipment, as if you had started with that CRS. Now everything is on the GPS/GNSS CRS.
This is now a common workflow for many of our users who are bringing old local surveys into modern coordinate reference systems used by their GPS/GNSS equipment So we reworked the process to be more thorough yet simpler to use. You’ll love it!
Convert to Survey Details
Turn on [x] Details to see everything that gets converted to survey along with duplicate
Transform Drawings
Turn on [x] Drawings to transform drawing data right along with survey data.
Its one of many new tools TPC includes for converting survey data from one CRS to another.
Calibrate Local to GNSS
Collect GNSS RTK or static points in the field and reference their existing survey points then use the new [x] Reverse (uncalibrated points as Side Shots or In point description).
This makes it easier to calibrate from GNSS to any local survey Coordinate Reference System, like 5000/5000.
Calibrate Survey
Now you can calibrate an entire survey from local to the CRS used by the project or your GPS / GNSS equipment.
In the dialog shown here, the entire survey is being calibrated, including [x] Raw Data and [x] Drawings.
The [X] Reverse Calibration can be selected to reverse the direction of the calibration, making it easy to calibrate a local survey to GNSS.
Select Survey Calibrations
Calibrations are as much a part of typical workflows now as COGO. So we’ve worked hard to make them easier to use. Like selecting from a list of calibrations already used by the survey.
In the dialog shown here, you can use the Select a Calibration list to pick a calibration you’ve already used for this survey.
The Calibration Information provides information about the calibration selected in the list, helping you pick the right calibration to use.
And you can always Browse to load a new calibration into the survey.
Calibration Report
TPC now reports rotation as both CW and CCW, making it easier to see how much rotation is in a calibration.
CSV Headers
Choose the new [x] Get format from header (overwrite format) to determine the import Format from the file itself.
The emlid CSV import format includes lots of characters and getting just one of them out of place can mess up the whole import. Let TPC figure it out for you and get it right every time.
Ignore Headers
Use the new Number of lines to skip [ ] to ignore headers line(s) when you import ASCII data.
Editing Headers
Some headers allow you to edit them right inside TPC, replacing TPC’s default header name with your own. The GNSS (CSV) filter is a good example of this.
In the example shown here, we have replaced the header key Attribute (default) with Code. to match the header used by some new GNSS equipment that doesn’t yet have it’s own filter in TPC.
Managing Headers
TPC stores header definitions in .dat files in the \Headers\ sub-folder of your program data folder. When you use the Save and Open icons shown with the red arrow, TPC accesses this sub-folder.
Column Headings
You can edit the column names used for any table in TPC. If you want to change the BEARING column in a curve table to CHORD BEARING, you can.
Managing Headers Definitions
TPC calls the name at the top of a column of data, a header. You can save these to a header definition file and recall them as needed to create tables for different clients.
Point Code Groups
Now you can group Point Codes, just like you do Traverses and Drawings.
When you use a lot of different point codes, grouping them can make life a whole lot easier.
