The only difference was the smaller image cache was created on a 16 bit raster vs the new image service would be using an 8 bit raster. Can anyone explain why or what would cause this massive difference in cache size (30 GB vs 80 GB)?</P></BODY></HTML> Fri, 19 Jul 2019 12:53:12 GMT https://community.esri.com/t5/arcgis-enterprise-questions/why-would-an-8-bit-raster-create-an-image-cache/m-p/638779#M24526 KyleCrawford2 2019-07-19T12:53:12Z Re: Why would an 8 bit raster create an image cache service twice the size of a 16 bit? https://community.esri.com/t5/arcgis-enterprise-questions/why-would-an-8-bit-raster-create-an-image-cache/m-p/638780#M24527 <HTML><HEAD></HEAD><BODY><P><A class="link-titled" href="https://pro.arcgis.com/en/pro-app/help/sharing/overview/configure-an-image-service.htm" title="https://pro.arcgis.com/en/pro-app/help/sharing/overview/configure-an-image-service.htm">Configure an image service—ArcGIS Pro | ArcGIS Desktop</A>&nbsp;</P><P>would there be any differences in compression methods used?</P></BODY></HTML> Fri, 19 Jul 2019 14:50:01 GMT https://community.esri.com/t5/arcgis-enterprise-questions/why-would-an-8-bit-raster-create-an-image-cache/m-p/638780#M24527 DanPatterson_Retired 2019-07-19T14:50:01Z
