I have just no clue on this problem. I want one raster to set its values to 0 or NoData based upon another raster noData or 0 values. It's like a reclassify, but between two different raster's. I have a picture here to help illustrate:
I have two raster here: one is a depth raster (the one with the reds and has a flow look to it) and the other is a velocity raster (the one with the straight breaks).
I'd like to have the Velocity raster only exist where the Depth raster exists. I think this needs to be done in raster calculator or a clip, but so far I haven't found any way to do this.
