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.

COORDINATE SYSTEMS APPS
Geodetic Packages (GEOPAK)

A geodetic package is a collection of geodetic metadata used for grid, graticule and magnetic verification for all NGA standard map products. The software to create a geodetic package is GEOPAK and is available at the NGA GEOINT APP Store. PKI certs required.

Tiled Image Converter 2.1

The Tiled Image Converter is a GUI based program built by the Naval Research Laboratory that is capable of converting entire pyramids of raster tiles away from the input map projections into one of the output map projections. The input map projections are web Mercator (also known as EPSG::3857), WGS 84 Plate Carree (also known as EPSG::4326), and Mercator. The output map projections are Mercator and Plate Carree. The software is available at the NGA GEOINT APP Store. PKI certs required.

MSP (Mensuration Services Program) GEOTRANS (Geographic Translator) v.3.7

MSP GEOTRANS is the NGA and DOD approved coordinate converter and datum translator. The user-friendly GUI has features including batch conversion capability, a choice of precision levels and the capability to add your own datum. MSP GEOTRANS can be run as an online web app or downloaded to run as a stand-alone application. Available downloads are listed in the table below. Click here to use the NGA web version.

The MSP GEOTRANS app is intended to be installed on Android 2.3 and later OS devices. The MSP GEOTRANS App is available through the NGA GEOINT APP Store on the SBU. A GEOINT Online account is required to access the GEOINT App Store. The MSP GEOTRANS app may also be downloaded using the link to the left.

NOTE: If the filename is different after downloading, be sure to rename the file for decompression purposes. After downloading one of the MSP GEOTRANS files, you may optionally verify that the downloaded file exactly matches the download file stored on the distribution server by generating an MD5 digest of your downloaded file. The MD5 digest value for your downloaded file must exactly match the MD5 digest published on this web page for the files to be the same.

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:

  1. Right click on Computer and select properties.
  2. On the left panel, click on Advanced system settings.
  3. At the bottom of the Advanced tab, click on Environment Variables...
  4. Under the System variables, select Path and click Edit.
  5. Change the Variable values for C:\ProgramData\Oracle\Java\javapath to C:\Program Files (x86)\Java\<your java version>\bin
  6. 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) at 800-455-0899 or email MSP_Help@nga.mil (Unclassified content only).

Description

Service info for elevation data sources used by the GVS basemap products. This service provides three different views of elevation datasets used to create the tinted hillshade for several GVS basemaps.

DBED0 is a global uniform matrix of digital bathymetry and elevation information that seamlessly represents the positive and negative heights of the Earth's physical surface above and below the oceans.

DTED is a uniform matrix of terrain elevation values. It provides basic quantitative data for all military systems that require terrain elevation, slope, and gross surface roughness information.

TERRAFORM is a Digital Elevation Model (DEM) data set in support of orthorectification activities.

SRT1F/SRTM2F is the finished production set of data where most of the voids have been filled. ALL SRTM DTED elevations are with respect to the reflective surface.

Worldwide basemaps depicting shaded relief derived from NGA's 1 kilometer and 90 meter TERRAFORM DTED, 30 meter TERRAFORM DTED2, NASA and METI's 30 meter ASTER GDEM v2 (used where TERRAFORM data is not available), USGS' 10 meter National Elevation Dataset (NED), NGA's Digital Bathymetric Elevation Dataset (DBED, 1 Kilometer), and NOAA's 90 meter coastal bathymetry (U.S. Coastal Relief Model).

  • Geodetic Survey Database (GSD) - Visualize control point data and download survey publications.
  • Geodetic Survey App (GeoSAPP) - Provides capability to access and extract Geodetic Survey data into customer specified format. It is designed to efficiently increase the calculations and procedures involved with processing runway profile data for airfield surveys. There are several other functions this program performs such as calculating the horizontal and vertical position of abeam points on airfield runways, determining the position of the touchdown zone on a surveyed runway, providing various other survey computation tools and providing a metadata builder for terrestrial lidar collections.
