Operations for color balancing and overviews were already applied.</SPAN><BR /><BR /><SPAN>Now my task is to merge these two large dataset in a single seamless mosaic. However I have been finding issues for color correcting this final product. No method seems to work when performing this operation. </SPAN><BR /><BR /><SPAN>Does anyone have any thoughts here?</SPAN><BR /><BR /><SPAN>Many thanks in advance!</SPAN></BODY></HTML> Tue, 17 Jun 2014 20:01:43 GMT https://community.esri.com/t5/data-management-questions/merging-two-large-mosaic-datasets/m-p/438726#M25045 HiranZani2 2014-06-17T20:01:43Z Re: Merging two large mosaic datasets https://community.esri.com/t5/data-management-questions/merging-two-large-mosaic-datasets/m-p/438727#M25046 <HTML><HEAD></HEAD><BODY><P>Hiran</P><P></P><P>In practice, what you can do is to add /import the second mosaic dataset into the first one (via Add ‘table’); remove all ‘overviews’, and then re-do color-balancing (conduct statistics on this new MD, if necessary); and finally create overviews again.</P><P></P><P>In fact, your issue is common, especially, when working ‘non pre-processed’ raster datasets within Mosaic Dataset model.</P><P></P><P>Worth to mention here, if your ‘500 scenes’ raster datasets are not ‘pre-processed’ (that is, color-balancing and spatial rectification are not done by other remote sensing package like ERDAS/ ER Mapper or PCI), it is really challenging for you to produce nice color-balanced Mosaic Dataset with clear features at full resolution.</P></BODY></HTML> Tue, 09 Sep 2014 12:33:42 GMT https://community.esri.com/t5/data-management-questions/merging-two-large-mosaic-datasets/m-p/438727#M25046 larryzhang 2014-09-09T12:33:42Z
