Good morning. I am trying to make maps in QGIS with information provided
through landscape metrics obtained through the program fragstats. The input
used to enter Fragstats is a sorted raster generated in QGIS; The raster is
made up of two values: 1 (wells and paths) and 0 (matrix). My problem is

Hi everybody
I'm doing a calculation with NDVI raster calculator. When I generate the
calculation results I get a lot of pixels without values (no data). How I
can do to fill those values with data?
Thank you so much

Hi everybody!!!
I'm trying to transform a raster file format (.gtiff) to a map file to
submit to Fragstat. My downside comes when I try to do this procedure from
the Raster / Conversion / Translate option. This leads me the following

Good night people!
I'm making masks that correspond to landscape units (LU). The polygon
corresponds to the LU called pampas. This polygon was done through the
creation of a vector and scanned with mouse function of landscape features

I connect with you because I want to do a reclassification on a raster

conservative=1 and conservative4 then 1
when conservative=4 and conservartive32 then 0
end
After that, you can try intersection... or union.
What about to work as raster?

When georreferenciacion apply this correction the image is lost. What I
