Is there anyone who wants to mentor such a project?

it with metadata. I often do this part in python.

if you have a sensor with more than this three channels
probably it will not work you need to have an RGB image.

The question is how you can build a VRT mosaic directly from MODIS hdf
files, because
the problem is that you have
5min modis swath file, by
default gdal only reads every 10th row and column of gcp's this is not
enough to handle the bowtie effect.

Hi,
There is a format called zmap format and it has Zmap Plus grid
does anybody know more info about this format?
mostly it is used for DEM and petroleum and according to my

that's why I am asking for some reference for zmap

I am using centos and elgis repo and for me it is working..
so there must be a problem with the hdf linking or compile of the library.
