In a few words I have two rasters Ras1 (bigger area) and Ras2 (small area but laser scan data) and I want to replace&nbsp;the Ras1 with values of Ras2 as Ras2 should provide me with a more accurate data. <SPAN>&nbsp;</SPAN></SPAN><BR /><SPAN style="border: 0px; font-weight: inherit;">Is there any way to replace raster values in Ras1 with Ras2 of my chosen area in the image?</SPAN></H1><P></P><H1 style="border: 0px; font-weight: 200; font-size: 2rem;"><SPAN style="border: 0px; font-weight: inherit;">Thanks</SPAN><BR /><SPAN style="border: 0px; font-weight: inherit;">Miquel</SPAN></H1></BODY></HTML> Mon, 03 Jul 2017 14:09:07 GMT https://community.esri.com/t5/data-management-questions/replacing-raster-values/m-p/577050#M32691 MiquelVinyals 2017-07-03T14:09:07Z Re: Replacing Raster Values https://community.esri.com/t5/data-management-questions/replacing-raster-values/m-p/577051#M32692 <HTML><HEAD></HEAD><BODY><P>If they overlap and same spatial reference, use <A class="link-titled" href="http://desktop.arcgis.com/en/arcmap/10.3/tools/data-management-toolbox/mosaic-to-new-raster.htm" title="http://desktop.arcgis.com/en/arcmap/10.3/tools/data-management-toolbox/mosaic-to-new-raster.htm">Mosaic To New Raster—Help | ArcGIS for Desktop</A>&nbsp;tool and make the mosaic operator refer to Ras2 in your input raster&nbsp;sort, as the following picture.&nbsp;&nbsp;</P><P><IMG alt="" class="image-1 jive-image j-img-original" src="https://community.esri.com/legacyfs/online/359900_raster_replace.jpg" style="width: 620px; height: 411px;" /></P></BODY></HTML> Mon, 03 Jul 2017 15:04:07 GMT https://community.esri.com/t5/data-management-questions/replacing-raster-values/m-p/577051#M32692 AbdullahAnter 2017-07-03T15:04:07Z Re: Replacing Raster Values https://community.esri.com/t5/data-management-questions/replacing-raster-values/m-p/577052#M32693 <HTML><HEAD></HEAD><BODY><P><A href="http://desktop.arcgis.com/en/arcmap/latest/tools/data-management-toolbox/create-fishnet.htm">Con</A> with <A href="http://desktop.arcgis.com/en/arcmap/latest/tools/spatial-analyst-toolbox/is-null.htm">IsNull</A> &nbsp; generically&nbsp; Con(IsNull(small), big, small) &nbsp;</P></BODY></HTML> Mon, 03 Jul 2017 15:07:29 GMT https://community.esri.com/t5/data-management-questions/replacing-raster-values/m-p/577052#M32693 DanPatterson_Retired 2017-07-03T15:07:29Z Re: Replacing Raster Values https://community.esri.com/t5/data-management-questions/replacing-raster-values/m-p/577053#M32694 <HTML><HEAD></HEAD><BODY><P>The MosaicDataset Fan is back: You should create a MosaicDataset and load both. Where one has a higher resolution than the other - it will be used - thats the simple version. There is a lot you can set as properties, too. No need to calculate them into a new dataset, if you dont want to. Though thats an option, no doubt.</P></BODY></HTML> Mon, 03 Jul 2017 15:15:24 GMT https://community.esri.com/t5/data-management-questions/replacing-raster-values/m-p/577053#M32694 GünterDörffel 2017-07-03T15:15:24Z Re: Replacing Raster Values https://community.esri.com/t5/data-management-questions/replacing-raster-values/m-p/577054#M32695 <HTML><HEAD></HEAD><BODY><P>Thanks for the answer Gunter. My only issue is that I have no access to the right licence to create a Mosaic Dataset under Data Management. Therefore I will follow Abdullah and Dan's advice.</P><P></P><P>Really appreciate though</P></BODY></HTML> Tue, 04 Jul 2017 07:45:37 GMT https://community.esri.com/t5/data-management-questions/replacing-raster-values/m-p/577054#M32695 MiquelVinyals 2017-07-04T07:45:37Z Re: Replacing Raster Values https://community.esri.com/t5/data-management-questions/replacing-raster-values/m-p/577055#M32696 <HTML><HEAD></HEAD><BODY><P>Thanks for the reply. Yes - it requires at least Standard licensing. If you work a lot with rasters it might be worth it just because of that. Hope you have success with the procedures described by Dan and Abdullah&nbsp;</P></BODY></HTML> Tue, 04 Jul 2017 08:09:02 GMT https://community.esri.com/t5/data-management-questions/replacing-raster-values/m-p/577055#M32696 GünterDörffel 2017-07-04T08:09:02Z
