Introduction
When projecting a dataset between two different datums, a transformation is required. Both equation-based and grid-based transformation methods are supported by MicroSurvey products. An equation-based transformation can use either a 3-parameter (dX, dY, dZ) or a 7-parameter transformation (dX, dY, dZ, rX, rY, rZ, ds) to translate between coordinates. A grid-based transformation uses binary files and interpolations that calculate the differences between the two geographic coordinate systems.
Mapping Folder Paths
The table below indicates the path to the Mapping folder where the contents of the ZIP files will be extracted..
| Product | Operating System | Location |
|---|---|---|
| MicroSurvey CAD (similar for inCAD, embeddedCAD, etc.) | Windows Vista or later | C:\ProgramData\MicroSurvey\MSCAD\yyyy\mscad\Mapping\ |
| FieldGenius (similar for EVR and Layout) | Windows Vista or later | C:\ProgramData\MicroSurvey\FieldGenius\yyyy\Mapping\ |
| FieldGenius (similar for EVR and Layout) | Win CE or Mobile | (Path may vary)\MicroSurvey FieldGenius\Programs\Mapping\ |
| FieldGenius for Android | Android 6.0+ |
\\Internal Storage\FieldGenius\Mapping (Verson 2.0 and newer can use the Gridshift Library within the program) |
| STAR*NET | Windows Vista or later | C:\ProgramData\MicroSurvey\StarNet\V?\Mapping\ |
The mobile products will only display certain coordinate systems once the required files are present in the Mapping folder.
