The USGS DEM writer creates and writes feature data to a USGS DEM folder specified by the DATASET directive. The writer searches the mapping file for the <WriterKeyword>_DATASET directive, which is required to be in the mapping file. The names of the USGS DEM output files written to the output dataset folder are determined from the fme_raster_filename attribute or from the FME Feature Type. The folder need not exist before the translation occurs. Any old USGS DEM files in the folder with the same name are overwritten with the new feature data. The USGS DEM writer distinguishes duplicate output files by appending numbers to the filenames. Please see About FME Rasters for details.
FME currently supports writing to the following horizontal datum, projections, and units. Please note that certain combinations of the following may be invalid.
Horizontal Datum: NAD 27, WGS 72, WGS 84, NAD 83
Projections: LL, UTM (TM)
Units: RADIAN, FOOT, METER, SECOND
