A number of complex formats cannot be directly read by MICRODEM:
- ADF ESRI grid format. Pick the
"w001001.adf" file (which will be the only large file in the
directory, and not the small "w001001x.adf"
file). An ADF file, like a shapefile, actually contains a
number of files which always have the same names (the directory name is what is unique), and
all files in the directory must be kept together. Failure to
do so will cause problems.
- JPEG2000 (JP2) compressed file; pick the JP2 file.
- ECW wavelet compression format for imagery.
- IMG grid format from ESRI.
- USGS SDTS
- NetCDF (for complex files, import might be problematic)
- Tiled Geotiff.
Other options implemented with GDAL
- Subset TIFF imagery, keeping multiband
- Merge imagery
To read these formats, you need GDAL which you should get from
- FWTools was the precursor of GDAL, but has not been recently updated, and
can not perform some of these operations.
You must indicate where
the GDAL binary directory exists if you do not do the default installation. By default this should be 'C:\OSGeo4W64\bin',
using that will be much less bother.
MICRODEM creates a
command line or batch file like "gdal_tranlslate
-of Gtiff mola128_clon0\w001001.adf mola128_clon0.tif".
This command will be written to the debug log. If there are problems, you can copy that
command into a CMD window, run it, and see the error messages to try to debug the
