Erdas .GIS And .LAN (ERD)
Erdas version 7.4 .GIS and .LAN image files are supported by the
GeoGateway library. In fact, some files earlier than version 7.4 are also
supported, but the new version 8.0 files may not be supported.
Both 8-bit, and 16-bit unsigned Erdas files are supported; however, 4-bit
files are not supported. Limited support for reading georeferencing
information exists, however, UTM zones and other detailed projection
information is lost on import or export. Bounds are properly preserved.
Only the .GIS or .LAN files are read by the GeoGateway library. None of
the auxiliary or trailer files are read or generated.
Export of Erdas .GIS and .LAN files is supported. These files are
exported with a type of "ERD".
The Erdas file may contain any number of image
channels of either eight bit or sixteen bit unsigned data types.
Georeferencing information will be written to the Erdas file if
it is Long/Lat or UTM. No other data types such as PCTs, or LUTs
can be written.
