I have a question on speeding up “Mosaic to New Raster” or finding an alternative. After completing a suitability analysis we are trying to define movement corridors. We used a modified CircuitScape that left 4 folders, each containing 1080 raster tiles across our study area. We now need combine all 1080 rasters in each folder then combine these 4 combined rasters into a final raster which will be analyzed for paths.
I tried a python script that just wouldn’t work so I went on to Model Builder. It iterates through the grids in the folder, collects the values (raster names), then mosaics all to a new raster. It has been running for 5 days now and the results window indicates it is working. I’m hoping it will conclude in the next day or 2. But, we still have 3 more folders, each with 1080 rasters, that need to be mosaicked. So….is there a way to speed up Mosaic to New Raster or is there an alternative I could use to produce the final grid?
The cell size is 270 meters, 540 x 540 columns and rows, 1 band, 32 bit floating. Thanks
