Using ArcGIS Desktop, 10.5.1 I need to iterate through hundreds of FGDB rasters (single band, 16-bit, unsigned) that are stored in a single FGDB. I need to modify each iterated raster with the Raster Calculator and output the resulting raster to a different FGDB.
The problem: I cannot "connect" the Iterate Rasters output to the Raster Calculator tool as an input. As shown in the image below, there is no input option:
Weirdly, I got the model to work if:
- I add the Raster Calculator tool without attempting to connect
- I input the Raster Calculator values, as shown below
- I hardcode the source FGDB path, as highlighted below (without the hardcoded path, the dreaded 000539 error occurs!?!?!?)
Arc then automatically connects the Iterator to the Raster Calculator, but through the Name bubble. I thought that the connection always had to be from the "green bubble"!?
Why can't I connect the iterator to the Raster Calculator as an input?
