I need to calculate the rasters such that they are common so I can run further analysis on them<IMG alt="" class="image-1 jive-image j-img-original" src="https://community.esri.com/legacyfs/online/385462_2.JPG" /></P></BODY></HTML> Fri, 01 Dec 2017 16:28:52 GMT https://community.esri.com/t5/spatial-data-science-questions/using-raster-calculator-to-recalculate-high-and/m-p/72069#M145 ChristophersonPooter 2017-12-01T16:28:52Z Re: Using raster calculator to recalculate high and low https://community.esri.com/t5/spatial-data-science-questions/using-raster-calculator-to-recalculate-high-and/m-p/72070#M146 <HTML><HEAD></HEAD><BODY><P><A href="https://geonet.esri.com/docs/DOC-1544"><STRONG>GeoNet Community Structure</STRONG></A>.... is this supposed to be in Web GIS?&nbsp; you might move it to a more appropriate location if it isn't</P></BODY></HTML> Fri, 01 Dec 2017 17:37:47 GMT https://community.esri.com/t5/spatial-data-science-questions/using-raster-calculator-to-recalculate-high-and/m-p/72070#M146 DanPatterson_Retired 2017-12-01T17:37:47Z Re: Using raster calculator to recalculate high and low https://community.esri.com/t5/spatial-data-science-questions/using-raster-calculator-to-recalculate-high-and/m-p/72071#M147 <HTML><HEAD></HEAD><BODY><P>I'm sorry I got confused with that part.
