JP2 provides lossless and lossy compression, typically with better compression than others. (Typically about 30-40% better than JPEG {lossy] or LERC {lossless} ). The format is computationally intensive and structure means that that is requires a lot of data access to read, hence is quite a bit slower then other formats. I would not convert imagery to this format unless storage size is the most critical aspects. There is a section in <A href="https://doc.arcgis.com/en/imagery/workflows/">Imagery Workflows</A> specifically on <A href="https://doc.arcgis.com/en/imagery/workflows/best-practices/imagery-formats-and-performance.htm">Imagery Formats&nbsp;</A>. This also references <A href="https://github.com/Esri/OptimizeRasters">OptimizeRasters </A>that can be used to convert imagery to more optimal formats such as TIF (with JPEG/Deflate), MRF (JPEG/LERC) or COG (JPEG/Deflate)</P></BODY></HTML> Wed, 21 Aug 2019 15:25:18 GMT https://community.esri.com/t5/arcgis-image-server-questions/should-jp2-be-used-in-mosaic-datasets/m-p/176783#M1475 PeterBecker 2019-08-21T15:25:18Z Re: Should jp2 be used in mosaic datasets? https://community.esri.com/t5/arcgis-image-server-questions/should-jp2-be-used-in-mosaic-datasets/m-p/176784#M1476 <HTML><HEAD></HEAD><BODY><P>Hi Peter,</P><P></P><P>Great links.&nbsp; Thanks for that - it is what I have been searching for.</P><P></P><P>Cheers,</P><P>Mark</P></BODY></HTML> Thu, 22 Aug 2019 02:20:29 GMT https://community.esri.com/t5/arcgis-image-server-questions/should-jp2-be-used-in-mosaic-datasets/m-p/176784#M1476 MarkChilcott 2019-08-22T02:20:29Z
