[Qgis-user] NDVI resolution

[Neels Brink]

Yes, the raster calculator, and the extent (resolution, nr of  pixels, everything)  of the output file matches that of the two input bands. What is interesting is that I noted that the boundaries of some man-made objects  do no show this fuzziness:

Hi,
Did you use the raster calculator?  If so, did you select the proper extent and rows and columns in the output files?

I created an NDVI in QGis from Worldview -3 bands. However, the NDVI looks ‘fuzzy’, or at lower resolution than the original bands. I tried to find a flag or setting which causes this but do not see something like it. What could be the reason for this appearance of the NDVI?
