Usage: l1mapgen argument-list
The argument-list is a set of keyword=value pairs. The arguments can
be specified on the commandline, or put into a parameter file, or the
two methods can be used together, with commandline over-riding.
return value: 0=OK, 1=error, 110=north,south,east,west does not intersect
file data.
The list of valid keywords follows:
help (boolean) (alias=h) (default=false) = print usage information
version (boolean) (default=false) = print the version
information
dump_options (boolean) (default=false) = print
information about each option
dump_options_paramfile (ofile) = print
information about each option to paramfile
dump_options_xmlfile (ofile) = print
information about each option to XML file
par (ifile) = input parameter file
pversion (string) (default=Unspecified) = processing version string
suite (string) (default=OC) = product suite string for loading
suite-specific defaults
ifile (ifile) (alias=ifile1) = input L1 file name
geofile (ifile) = input L1 geolocation file name (MODIS/VIIRS only)
resolution (int) (default=-1) = processing resolution (MODIS only)
-1: standard ocean 1km processing
1000: 1km resolution including aggregated 250 and 500m land bands
500: 500m resolution including aggregated 250 land bands and
replication for lower resolution bands
250: 250m resolution with replication for lower resolution bands
ofile (ofile) (alias=ofile1) (default=output) = output file name
oformat (string) (default=ppm) = output file format
ppm: output a netPBM PPM file
png: output a PNG file
tiff: output a geoTIFF file
north (float) (default=-999) = north boundary
south (float) (default=-999) = south boundary
east (float) (default=-999) = east boundary
west (float) (default=-999) = west boundary
width (int) (default=600) = width of output image
threshold (float) (default=0.1) = threshold for the number of good pixels
before an image is produced
rgb (int) (default=[1,1,1]) = bands to use for red, green and blue
atmocor (boolean) (default=on) = toggle atmospheric correction
datamin (float) (default=0.01) = minimum reflectance for scaling
datamax (float) (default=0.9) = maximum reflectance for scaling
stype (int) (default=0) = scaling type
0: log
1: linear
This program produces a PPM-formatted output image rendered in a Plate Carree
projection.
The default band combination produces a "true-color" image. Other combinations
may be chosen with the "rgb=" option. The expected argument to this option is
a comma separated string of wavelengths that specifies the desired bands in
red-green-blue order. For example, to produce a false color SeaWiFS output
image using 865, 670 and 555 nm as the red, green, and blue values
respectively, the option would be specified as "rgb=865,670,555".
cirrus_opt (boolean) (default=false) = cirrus cloud reflectance correction option
atrem_opt (int) (default=0) = ATREM gaseous transmittance bitmask selector
0: H2O only
1: Ozone
2: CO2
4: NO2
8: CO
16: CH4
32: O2
64: N2O
atrem_full (int) (default=0) = ATREM gaseous transmittance calculation option
0: Calculate transmittance using k-distribution method (fast)
1: Calculate transmittance using full method (slow)
atrem_geom (int) (default=0) = ATREM gaseous transmittance geometry option
0: Only recalculate geometry when error threshold reached (fast)
1: Recalculate geometry every pixel (slow)
atrem_model (int) (default=0) = ATREM gaseous transmittance Atm. model selection
0: Use pixel's latitude and date to determine model
1: tropical
2: mid latitude summer
3: mid latitude winter
4: subarctic summer
5: subarctic winter
6: US standard 1962
atrem_splitpaths (int) (default=0) = ATREM gaseous transmittance split paths between solar and sensor (turns atrem_full on)
0: Calculates transmittance over total path length (default)
1: Calculates transmittance over separate solar and sensor paths (slow)
