INTRODUCTION

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.
