I currently have a fairly large raster (1000, 1000). I have a vector layer of reservoirs. I need to create a 100 m buffer around the reservoir, assign it a land use code and merge it with the larger raster.
I have created the buffer, converted the buffer to raster and then classified it using my land use codes. I then used the mosaic tool to merge the two raster layers. I end up with something like this. The raster layer for my buffer, is a large square and doesn't cover the area of the buffer.
I am wondering if this is because my original raster is so large and the buffer is so small?
What is the best way to go about, creating the buffer, assigning the land use code and merging it with the larger raster?
I am using ArcGIS for Desktop and have access to Spatial Analyst.
