Hi guys,

I can't find a software (best if free or open source) or the function which allows me to convert severeal grayscale images to a multi band image. For example for creating a multi band landsat image out of single bands from the global land cover website.
On the other hand I want to create single band images from a multi band aster image for creating a NDVI Index. Do you know software which can handle this?

Thanks a lot

Maybe OSSIM or MicroDEM will do what you need.

GRASS would do it too. As for commercial - I've used IDRISI to do this.

I used IDRISI for the NDVI section of my thesis :) That was good.

thank you guys.

I've also found another solution: doing it with SAGA GIS. SAGA imports the multi band image as X seperate single band layers. It's easy to export or combine them.
For creating mutli-band-layers I've only found in SAGA GIS a RGB-Combination function, not a function for combining more than 3 layers, but it's ok. I will take a look at IDRISI, and of course also to GRASS (via qgis or the python GUI)

Thank a lot

Photoshop and ArcGIS can do this to. I assume Global Mapper can as well.

If you have Adobe Photoshop, you might want to try this :)
