I need to add different boolean rasters of the distribution of some species, since we need to obtain a single file that shows the locations where there are more than one species occurring.
To do that, I rasterized all of the shape files showing the distribution and then reclassified them to obtain the boolean rasters.
The problem is, now that I'm trying to add them all together using rastercalc, there are files with different extends even though I clipped them with the same shape file (the final single file -the one that I obtain by adding all of the booleans, is all cut and incomplete with null values)...
how can I change them to the same extent in order to obtain the complete map... ?
the first picture is the shape file I used to clip the other shape files (this is the polygon of the state I live in).
The second picture shows an example of one boolean images with the raster of the shape I clipped them (the state's shape)
The third one shows the last raster with all of the boolean rasters together... if you compare images 2 and 3, you will see there is lots of missing data
