Details
l1mapgen creates a Level 1 mapped image. The following image shows the default GUI for l1mapgen.
l1mapgen GUI without GEOFILE
 |
When l1mapgen requires a geofile to create a level 1 mapped image, such as in the case of modis data,
the geofile gui element is dynamically added, as shown in the image below.

Command Line Usage
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.
The list of valid keywords follows:
-help (boolean) (alias=-h,--help) (default=false) = print usage information
-version (boolean) (alias=--version) (default=false) = print the version
information
-dump_options (boolean) (alias=--dump_options) (default=false) = print
information about each option
-dump_options_paramfile (ofile) (alias=--dump_options_paramfile) = print
information about each option to paramfile
-dump_options_xmlfile (ofile) (alias=--dump_options_xmlfile) = 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 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 L2 file #1 name, output vicarious L1B
for inverse mode
ofile[#] = additional output L2 file name
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
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
outmode (int) (default=0) = defines output format
0: PPM
1: PNG
2: GeoTIFF
