The GeoTIFF writer supports additional options through the Feature Type Properties dialog.
Please see Writer Feature Type Parameters for Workbench-specific information.
Writer Mapping File Directives
The suffixes shown are prefixed by the current <WriterKeyword> in a mapping file. By default, the <WriterKeyword> for the GeoTIFF is GEOTIFF.
DATASET
The value for this directive is the path of the output folder where the data will be written.
Required/Optional
Required
Mapping File Syntax
GEOTIFF_DATASET “C:\DATA\GEOTIFF\OUTPUT”
Workbench Parameter
Destination GeoTIFF Folder
WRITE_OFFSETS_IN_CS_UNITS
When the value is set to Yes, the coordinate system offsets will be written to the GeoTIFF file in the linear units of the projection. This is correct according to the GeoTIFF specification.
When set to No, the coordinate system offsets will be written in meters. This is what is actually done in practice by many software packages.
Required/Optional
Optional
Values
Yes (default)| No
Mapping File Syntax
WRITE_OFFSETS_IN_CS_UNITS “Yes”
Workbench Parameter
Offsets in Coordinate System Units
WRITE_PROJECTED_COORDSYS_AS_EPSG_CODE
The projected coordinate system in GeoTIFF may be stored either by specifying an EPSG code or by marking the coordinate system as user-defined.
Some software packages may have better compatibility with one of these methods over the other.
Required/Optional
Optional
Values
- Yes (default): write an EPSG code if possible
- No: mark the projection as user-defined
Workbench Parameter
Write Projected Coordinate System as EPSG Code
WRITE_GEOGRAPHIC_KEYS_FOR_PROJECTED_COORDSYS
Specifies whether GeoTIFF geographic coordinate system keys (for example, GeographicTypeGeoKey, GeogCitationGeoKey, etc.) should be written for projected coordinate systems.
Generally it is not harmful to write these keys, but some standards may require these keys be omitted for projected coordinate systems.
Required/Optional
Optional
Values
Yes (default) | No
Mapping File Syntax
WRITE_GEOGRAPHIC_KEYS_FOR_PROJECTED_COORDSYS No
Workbench Parameter
Write Geographic Keys for Projected Coordinate Systems
IGNORE_RASTER_TYPE_KEY
GeoTIFF contains a “raster type” key which specifies whether each pixel in the file represents an area (“PixelIsArea”) or a point (“PixelIsPoint”).
When reading PixelIsPoint data, the raster extents should be shifted up and left by half a pixel when transformed to the FME georeferencing model. Setting this value to Yes prevents this adjustment from happening.
Required/Optional
Optional
Values
Yes| No (default)
Mapping File Syntax
IGNORE_RASTER_TYPE_KEY Yes
Workbench Parameter
Ignore Raster Type Key
WRITE_PROJECTED_COORDSYS_AS_EPSG_CODE
The projected coordinate system in GeoTIFF may be stored either by specifying an EPSG code or by marking the coordinate system as user-defined.
Some software packages may have better compatibility with one of these methods over the other.
Required/Optional
Optional
Values
- Yes (default): write an EPSG code if possible
- No: mark the projection as user-defined
Workbench Parameter
Write Projected Coordinate System as EPSG Code
WRITE_GEOGRAPHIC_COORDSYS_AS_EPSG_CODE
The geographic coordinate system in GeoTIFF may be stored either by specifying an EPSG code or by marking the coordinate system as user-defined.
Some software packages may have better compatibility with one of these methods over the other.
Required/Optional
Optional
Values
- Yes (default): write an EPSG code if possible
- No: mark the geographic coordinate system as user-defined
Workbench Parameter
Write Geographic Coordinate System as EPSG Code
WRITE_ESRI_COMPATIBLE_COORDSYS
This option attempts to adjust some coordinate system geokeys to have better compatibility with Esri applications.
Required/Optional
Optional
Values
- Yes: adjust coordinate system geokeys to improve compatibility with Esri products
- No (default): write typical geokeys
Workbench Parameter
Write Esri-Compatible Coordinate System
