topic Mosaicked DEM has half the range of values of the originals in Data Management Questions https://community.esri.com/t5/data-management-questions/mosaicked-dem-has-half-the-range-of-values-of-the/m-p/341738#M19468 <HTML><HEAD></HEAD><BODY><SPAN>I have two DEMs that I would like to stitch together for least-cost path analysis. One DEM ranges from 100-399; the other ranges from 182-474.</SPAN><BR /><BR /><SPAN>I've tried several approaches. I created a mosaic dataset and added the rasters to it, which results in a big grey rectangle. I had the most luck with the Mosaic to New Raster tool, but the resulting raster has values from 93 to 255--about half the range of the original rasters, and not nearly enough contrast for what I need. I'm not sure what I'm doing wrong--I just want a raster that has the same elevation data as the original two rasters, but in one dataset! Any ideas?</SPAN><BR /><BR /><SPAN>Thanks!</SPAN></BODY></HTML> Sun, 28 Apr 2013 02:47:48 GMT ErinWarford 2013-04-28T02:47:48Z Mosaicked DEM has half the range of values of the originals https://community.esri.com/t5/data-management-questions/mosaicked-dem-has-half-the-range-of-values-of-the/m-p/341738#M19468 <HTML><HEAD></HEAD><BODY><SPAN>I have two DEMs that I would like to stitch together for least-cost path analysis.
