Abstract
MODIS data are free geodata and they are crucial to derive ecological indicators. The two NASA satellite systems, Terra and Aqua, significantly improve the current data availability for scientific purposes. I am facing the challenge to develop a module which will be able to:
- import data from a downloaded file
- directly download MODIS data from a FTP server and then load the file(s) in a GRASS GIS location.
Application
Idea
The idea was little changed from the initial idea that I wrote in the GSOC propose. I spoke with my mentor and we think that the best solution is create three modules:
- r.modis.download: to download the MODIS products using pyModis library. It will be able to download more tiles and different range of times
- r.modis.import: to import Level 3 MODIS products, it will use pyModis library to parse the XML files and MODIS Reprojection Tool. It will be able to import single tile or creates a mosaic for more tiles of the same day
- r.modis.process: to process and import MODIS raw data using MODIS Reprojection Tool Swath
