TPC Desktop 2024 R0

We’ve added photos for survey points and traverses.

Why Add Photos?

Using Photos

Points

It can be advantageous to add a photo to a point so you can visualize exactly what that point looked like in the field. Some examples being: survey monuments, aerial control points, utilities and as-builts.

Traverses

It can be advantageous to add a photo to a traverse so you can visualize the area or feature associated with that traverse. Some examples being: building or other structure, lake, river, fence line.

Adding Photos

Survey Point Photos

You’ll find lots of neat photo tools, like the Photo tab shown here in the Point Properties.

Survey Point Properties Photos tab

One of our favorite new photo tools is the ability to insert a photo into a drawing. Since TPC already knows which photo is associated with each survey point, you just tell TPC to insert the photo then place it next to the point.

Inserting Photos Into a Drawing

Traverse Photos

Traverses can have photos also. In the photo shown here, we’ve staked out a foundation and taken a picture to send to the contractor. So why not attach that photo to the traverse with the stakeout points? Done!

Traverse Photos

Think of all the possibilities for your site/topo surveys where you survey a rock wall, a retention pond, a driveway cut, and all with a photo to provide that extra documentation.

Averaging GPS/GNSS

Beginning with TPC Desktop 2024, when you take multiple GPS/GNSS observations of a survey point, TPC can average those observations to improve the accuracy of that point’s position.

Averaging GPS/GNSS

NGS User Guidelines

In their User Guidelines, NGS says “RT positioning of important data points cannot be done reliably without some form of redundancy”. They provide guidelines on how to create these redundant observations.

See NGS Guidelines for Averaging GPS/GNSS

Specifying Redundant GNSS Observations

Beginning with TPC Desktop 2024, TPC provides four ways to specify redundant GNSS observations. Each way relies on raw GNSS observations being stored with a traverse point.

Specifying Redundant GNSS Observations

Depending on the data collector or GNSS receiver you are using, you can tell TPC how to identify redundant observations.

Editing Redundant GNSS Observations

The GNSS Averages dialog display the selected GNSS points to be averaged, along with their redundant observations.

GNSS Averages dialog

Its easy to select outliers and reject them from the average computations.

Then, just update the survey points with the computed averages.

Individual Survey Point Averages

In the Survey Point Properties dialog, you can bring up all the GNSS observations for that point and the computed average.

Updating a Survey Point’s GNSS Average

Available in Professional Edition.  Compare Editions

GNSS Traverses

The Traverse View now displays GNSS observations. For RTK, you’ll see the base station and each rover position as a new RTK point type.

And in your drawings, BASE points plot like Control points and RTK rover points plot like side shots. So you can reuse all your customized Traverse Drawing Settings to draw your GNSS survey.

Traverse View GNSS Data

The Traverse View now displays raw data for all your GNSS observations.

In the picture shown here, we’ve turned on RMS, PDOP and count so you can double check your results.

GPS/GNSSNSS Data

Rejecting GNSS Observations

When you tell TPC to compute GNSS averages, TPC can help you identify any observations that are outliers. You can then choose to reject those observations. TPC does not use rejected GNSS observations for GNSS average computations.

You reject observations by UnSelecting (untagging) them in the GNSS Averages dialog. or by rejecting the raw GNSS data in the Traverse View.

Conversely, you accept them by Selecting (tagging) them.

Accepting & Rejecting GNSS Observations

Emlid Point Code Table

We’ve added a pre-defined Point Code Table you can use with your emlid Flow data. Each point and line in emlid’s default code library has a Point Code in TPC

Using emlid Point Codes

Plus, we’ve added dozens of new point symbols to support emlid default code library.

Without a Hot Spot

Once again, we’ve done the research, so you don’t have to.

If you are in the field and don’t have a hot spot to share data via the cloud, we provide step-by-step instructions and videos on how to share data via your Android or iOS device.

Sharing emlid Data Without a Hot Spot

Google Earth/ESRI

The EPSG-3857.prj and EPSG-4326.prj projection files now ship standard with TPC so you can more easily coordinate your surveys with Google Earth and ESRI.

These are defacto standard projections used by their mapping software.

PRJ Files

Transform with PRJ

You can now use prj files to specify a CRS to transform coordinates to or from.

In the example shown here, we are transforming to a NAD_1983_HARN… projection.

Transforming Coordinates

Latest CAD Drivers

This version includes the latest CAD drivers for DWG, DXF and DGN files.

Cloud Drives

Many of you are now using cloud drives like One Drive, DropBox, Google Drives and others.

We’ve improved the ability of TPC to work with those drives for your survey and program data.

In the example shown here, we’re saving our surveys to OneDrive and using a mapped drive for shared surveys.

Walk Through a Survey

We’ve added more tutorials on walking through a survey.

Each walk through targets the type of surveys you do most.
