World Magnetic Model (WMM) 2015 - Apps
World Magnetic Model 2015 - Data
WMM 2015 has been replaced by WMM 2015v2 below.
World Magnetic Model 2015 Update (WMM 2015v2) - Data
An update to the World Magnetic Model (WMM) 2015 was released October 2018 and can be downloaded below. The file contains the necessary coefficients to upload into systems that require the update. A full report with more information about the WMM and this update will be published by NOAA's National Center for Environmental Information on their website when the partial government shutdown is over. This update will not impact the release of WMM 2020.
The WMM is the standard model used by DoD, NATO, and IHO for a wide range of positional and navigation systems. Feedback from the WMM user community as well as the degree of the variation in the northern hemisphere drove the decision to make this out-of-cycle update. The model seeks to mitigate any user performance degradation caused by a one-degree gridded variation (GV) in the polar region. An increased GV error may adversely affect compass navigation and other magnetic field-based systems in the arctic region.

MSP GEOTRANS Assistance
Having trouble starting GEOTRANS? Here
are some suggestions
If you have installed GEOTRANS and are
unable to get it to start (no message given) you may need to download
the MS Visual C++ Redistributable Package. This software is normally
included on a computer, but system configurations do vary. Please
read the instructions for installing GEOTRANS on a
Network Drive.
MS Visual C++ Redistributable Package for 32-bit user download: http://www.microsoft.com/en-us/download/details.aspx?id=5582
MS Visual C++ Redistributable Package for 64-bit user download: http://www.microsoft.com/en-us/download/details.aspx?id=14632
NOTE: Java 32-bit and 64-bit may be required to run MSP GEOTRANS. GEOTRANS 3.7 was built using Java JDK 1.8 update 72. The latest releases of Java can be found at Orcale.com. Should you encounter a Windows Error 2 condition during MSP GEOTRANS install, this error usually occurs because the wrong bit-level for Java was selected. Especially with Java 1.8, the Windows environment variable for PATH is often not set correctly. You may try the following procedure to correct the condition:
- Right click on Computer and select properties.
- On the left panel, click on Advanced system settings.
- At the bottom of the Advanced tab, click on Environment Variables...
- Under the System variables, select Path and click Edit.
- Change the Variable values for C:\ProgramData\Oracle\Java\javapath to C:\Program Files (x86)\Java\<your java version>\bin
- Click Ok and exit out of the Advanced tab.
Contact the MSP/GEOTRANS Help Desk
For assistance with MSP GEOTRANS software, including questions about
source code, please contact the NGA Enterprise Service Center (ESC)

Gold Data v6.3 Testing For Datum Transformations and Coordinate Conversion Software
While GEOTRANS is the NGA recommended and supported software package for Datum Transformations and Coordinate Conversions, there are occasions when something else is requested or proposed, and needs to be tested. For such occasions, software developers are invited to download the following ZIP collection of test files. These are files created by NGA geodesists working independently of GEOTRANS. The files are simulated data (not measurements) and provide a higher accuracy standard for software performance than does GEOTRANS as of 3/25/2009 for the algorithms treated. Also, in some cases, they allow input values that GEOTRANS does not. Therefore, if developers have not carefully defined the domain of valid inputs and implemented the corresponding input checking, these tests are likely to reveal the lack thereof. The files "Instructions.doc" and "Release_Notes.doc", found in the ZIP, contain further information. This is an ongoing project, and more tests will be added in later releases. Comments are welcome at the e-mail address below.
