DESCRIPTION
|
Read,
write,
convert and display raster satellite images (also in Meteosat8 HRIT
format).
Provide:
msat can be used as a simple commandline tool allowing to:
- Read images in HRIT, GRIB version 1, SAF HDF5 and
some
NetCDF based formats (COARD S compliant).
- write images in GRIB version 1, JPG, PNG and some
NetCDF based formats (COAR DS compliant).
- Crop and scale images
- Convert between file formats
- Reproject satellite view data in a regular
latitude longitude grid of selected resolution
- Precisely correlate every pixel with its
geographical coordinates
- Display images

  Composit
with the high Resolution
Visible (HRV) Image from SEVIRI.
The png image is
created from native HRIT SEVIRI data format following the standard
procedure:
msat
--png --Area=35,50,5,27 -resize 400,400 H:MSG1:HRV:200702130900
msat
--png --Area=35,50,5,27 -resize
400,400 H:MSG1:IR_016:200702130900
and then composing the resulting images in a RGB composit by using the
"convert -combine" option of ImageMagick. with R=IR_016,
G=HRV,
B=HRV
