I have a series of raster files (150 or so) that I need to multiply by a baseline raster. Unfortunately, the series of rasters have a different cell size (30mx30m aka .00027777778 degrees x .00027777778 degrees) than the baseline file (.1 degree X .1 degree).
I ran a test using qgis' raster calculator (which is under the menu path: raster->raster calculator...) and it worked fine as far as I can tell. That is, QGIS was able to reconcile the differing cell sizes and complete the action as expected. However, when I went to batch the process, I discovered its not possible-- at least not from the GUI.
When I tried the SAGA, GRASS, and GDAL_CALC algorithms it appears the differing cell sizes are presenting issues. As a note, the basline file currently has a worldwide extent whereas the other files are smaller subsets.
My question: Is there a way to call QGIS' raster calculator as a batch process or from a scripting language? If not, is there an alternative solution?
Thanks!
