[GRASS-dev] How to import data from LSASAF

[António Rocha]

Hello

I'm trying to import, to GRASS, data from LSA-SAF project 
(http://landsaf.meteo.pt/). This project pretends to freely disseminate 
EUMETSAT data related to Land, Land-atmosphere interaction; biospheric 
applications, etc. LSASAF data is freely distributed in HDF5 files. I 
have created a script to import the different subsets from HDF5 to GRASS 
but, due to the fact that each file doesn't include and geocoding, i can 
only import in an non-earth arbitrary coordinate system. According to 
LSASAF team, each acquire image data is corrected for radiometric and 
geometric effects and geo-located using a standardised projection 
(GEOS). But no geocoded data is available. Externally, a latitude 
pixel-position dataset and longitude pixel-position are provided, in 
HDF5 format. My question is how can I import this data, with their 
geolocation, to grass IN WGS84 or any other system? The part of 
selecting and importing a subset is done but without any georreference 
information.


By the way, when I solve this I will Wiki this information just like we 
have for MODIS (http://grass.osgeo.org/wiki/MODIS) or Quick bird 
satellite data (http://grass.osgeo.org/wiki/QuickBird).

Thank you

Best regards,
Antonio
