I'm a relative newcomer to ArcMap.
I need to create one layer from three raster tiles that show presence/absence (0/1) of woody vegetation (background below). The three layers are publicly available here:
ftp://tern-auscover.science.uq.edu.au/nsw_spot_woody_extent_and_fpc/ The specific files are:
Viewed by themselves, the raster layers are fine with sharp edges like this
After I create a mosaic dataset, and add the first raster layer it appears fuzzy on the edges like this.
I've been careful to match coordinate systems, and have tried snapping to the input file raster.
Any suggestions for what I'm doing wrong?
[the background: for my doctoral research, I need to measure the amount of woody vegetation within a 500m radius of my study sites on farms. My sites are spread across a large area that encompasses the three raster tiles above. Unfortunately, a few sites are directly on the join between two tiles (ie. they overlap). Therefore I am trying to create a single layer so that I can then perform the analysis of amount of woody vegetation cover]
