A geographic transformation converts data between two geographic coordinate systems. If both the source and destination coordinate systems have been provided, then a list of valid transformations will be provided in the pull down menu. Selecting a transformation from the pull down menu will simultaneously set the Geographic Transformation Direction to the appropriate direction.

Click here to see a PDF of valid geographic transformation names for this parameter. Names of custom (user created) geographic transformations may also be used.

Note: The geographic transformation name is case-sensitive. If you do not enter the parameter in the correct case, FME will fail and produce an error saying it cannot locate the transformation parameter.

Note: Some geographic transformations require transformation grid files that are not present in ArcGIS by default. If such a transformation is chosen, no error will occur, and no geographic transformation will be applied to the features. Examples of installing additional grid shift files in ArcGIS can be found here.

You can also enter GEOGTRAN Well Known Text that represents a geographic transformation.

Note: To use this feature, you must have an Esri CustomTransformations folder. ArcGIS Desktop installations automatically create this folder. The CustomTransformations path is specific to the ArcGIS version and type (Server, Desktop, etc.).
ArcGIS 10.0 Example:
%APPDATA%\ESRI\Server10.0\ArcToolbox\CustomTransformations
ArcGIS 9.3.1 Example:
%APPDATA%\ESRI\ArcToolbox\CustomTransformations

This is the transformation direction (either "forward" or "reverse").

The Interpolation Type affects only raster data. Cell values are interpolated in order to change the raster to the specified size.

• Nearest Neighbor is the fastest but produces the poorest image quality.
• Bilinear provides a reasonable balance of speed and quality.
• Bicubic is the slowest but produces the best image quality.
• Average 4 and Average 16 have a performance similar to Bilinear and are useful for numeric rasters such as DEMs.

The Cell Size applies only to raster features.

• Stretch Cells: The cell size of the raster will be adjusted to maintain the same number of rows and columns in the reprojected raster as there were in the input raster.
• Square Cells: The number of rows and columns as well as the spacing will be changed to maintain approximately the same cell ground area and form square cells where the horizontal and vertical cell sizes are equal.
• Preserve Cells: Like the Square Cells option, this option will change both the number of rows and columns and the spacing to maintain cell ground area, but will also try to preserve the original cell aspect ratio, taking into account any warping caused by the reprojection.
