I have a geodatabase containing multiple rasters across the same extent with values of either null or 1. The goal is to merge these so where values of 1 overlap, the cell values are aggregated. Exactly the same as '+' in the Raster calculator tool.

This has worked using 'Mosaic to New Raster' however each raster dataset must be input separately into the model. I want to input all the data into the tool from one location.

Using ModelBuilder in ArcGIS Pro 2.1.2

  • Have a look at the cell statistics tool in toolbox

  • I'd like to run this as part of a wider model so I'd like the selection of the rasters within the geodatabase to be automatic. Cell Statistics requires manual input I believe?

Iterate the rasters in the geodatabase (recursive turned on) to the Collect Values tool. The output of this can then be input into Mosaic To New Rasterenter image description here

    Your iterator feeding into the collects tool, they need to be in a sub-model. Your current design whilst "works" is highly inefficient. Search Help or this site for sub-models.
