Trimble GPS Analyst Extension for ArcGIS Desktop Update

Trimble has released an update for GPS Analyst v2.40 (TGA240Update003) in response to the Esri reported issue SPRT00000726462: Start Editing on GPS Analyst Toolbar Causes ArcMap to Crash.

The TGA240Update003 is available both when you install GPS Analyst for the first time (it is automatically offered as a separate download), and when you already have it installed and use the option “Check for New Updates Now”.

Attention Authorized Callers: Your Global Account Can Unlock Features on the Support Services Website.

Support Services is constantly updating the functionality available on the Support Services Website. The key to accessing all of the capabilities of the support website is to login using an Esri Global Account ID.

While anyone with an Esri Global Account can access certain functionality – such as finding bugs online, submitting ideas, reading blogs and technical articles, and joining the forums – customers that are considered “Authorized Callers” will also have the ability to log email- or chat-based support incidents, view and manage an organization’s open support issues and more.

What is an Authorized Caller? They are the folks within an organization who can open an official incident with Esri Support via phone, email or chat. Customers that have a valid maintenance contract with Esri Support are entitled to a certain number of “Authorized Callers.”

How is someone setup as an Authorized Caller? Esri Support Receptionists manage the Authorized Caller database within Support’s Incident Management System. Once an organization identifies the individuals who will act as an Esri Support Authorized Caller, the following information will be requested:

  • Esri Customer Number

  • Customer Name

  • Customer Email Address

  • Customer Phone Number with Extension*

*If the last four digits of all phone numbers are unique for all Authorized Callers in an organization, an extension is not required. If all phone numbers end in the same four digits and the organization does not use extensions, generic 4-digit extensions will be generated and provided for validation purposes.

For example, I might provide the following:

Esri Customer Number: 123456
Customer Name: John Smith
Customer Email Address:
Customer Phone Number with Extension*: 888-377-4575 x8797

This individual’s information would be added into Support’s Incident Management System and used to validate incident requests.

Creating and Configuring an Esri Account

Once Support has received the necessary information from an Authorized Caller, that caller is then ready to create a new Esri Global Account and link it to the Esri Support database. Note that if you already have an Esri Global Account, you will not need to create a new one.

Tying it all Together

After being added as an Authorized Caller and then creating an Esri Global Account, the final step to unlocking all of the functionality of the Esri Support website is tie the two account together through “account validation”.

Navigate to the Support website home page and enter your new Esri Global Account username and password into the Support Center Login dialog.





Once you have successfully logged in, click on the “My Support” button in the center of the page.




A validation dialog will appear.








In order to validate your account, you’ll need to enter:

  • The same Customer Number you provided when becoming an Authorized Caller

  • One of the following:

    • The last four digits of your unique phone number; No extension is required

    • The last four digits of your company’s phone number; your extension

    • The last four digits of your company’s phone number; the generic extension provided when becoming an Authorized Caller*

If you have any problems validating your account or using the Online Support tools, please click on the “Feedback” button at the bottom of the Web page.

With a validated Esri Global Account, you can:

Search Results Feedback Brings Changes

We’re making some changes to our support site search, based on user comments, to enhance the overall experience on the site.

Effective immediately, you can experience the following update in our search at

Less omitted results: While searching for commonly-used terms, you may have previously seen a message: “In order to show you the most relevant results, we have omitted some entries…” (see the image below).

We have made this update to the Search Engine Results Page, enabling all results to  be shown for the following repositories:

  • ArcScripts

  • Bugs

  • Data Models

  • Technical Articles

  • Patches and Service Packs

  • Product Documentation

  • Samples and Utilities

  • White Papers

Our belief is that this update will vastly improve the search experience for our users and will also help you find what you’re searching for quicker. We’ll consider removing this filter for all repositories, depending on the future feedback we receive.

Want more changes? Use that feedback button because we are listening. Also, keep an eye on the Esri Support site, because we’ve got plenty of other enhancements coming soon!

Null Doesn’t Mean Zero?

How to add different-sized rasters with NoData Values 

One of the most common forum topics is on how to add two rasters with different spatial extents and get a result more than just where the two rasters overlap. Well, the reason the result is only those areas has to do with null values.

There are environment variables to modify to ensure that the rasters line up (snap raster) and the extent is preserved during the process (Spatial Extent). Fixing the environment setting alone will still not fix the output of the process. If you modify the spatial extent to match the “union of inputs”, the output raster will have the correct spatial extent, but the only values will be the values where the two rasters overlapped. So what is going wrong?

Obviously it is the pixel values … or, wait, I guess it isn’t that obvious. Try this piece of wisdom provided by forum poster and Product Engineer, Eric R.

Pixel value + NoData Pixel = NoData Pixel
Pixel value + 0 = Pixel value
Pixel value + Nothing (because your extents are different) = Nothing.

Two different rasters used in calculation (NoData is red).

Sum of Rasters

You may be asking, “What is actually happening? Are the values being used in the analysis or not?” Well, the answer is they will be as long as part of that equation doesn’t include a null value. If there is a null value present that will make the output null, then the output will not be correct. 

The next question is how to fix it. Bear in mind, both solutions require you to make the rasters that are being used as the inputs match in spatial extent, pixel registration and cell size. You can use the Copy Raster tool and set the appropriate environment settings to accomplish this. Once you have corrected the rasters, then there are two options depending on the desired output,

1. Set the NoData values to a value of zero, so that when they’re added together, the output will have the correct spatial extent and values from both rasters.

Output from Setting the NoData value (blue pixels = 0)

2. Utilize the Con( IsNull ) workflow to include all of the pixels and add them where appropriate.

Con(IsNull(“RasterSMALL”),”RasterBIG, (“RasterSMALL” + “RasterBIG”))

Output from Con Tool

To recap, there are options to handle the NoData cells. Depending on what output you’re trying achieve, there are different techniques. It’s also important to understand the effect that NoData has when used in raster calculation. 

There is a related forum post that discusses using Python to sum multiple rasters together: Calculate sum of 2334 raster layers.
