https://community.esri.com/t5/data-management-questions/block-adjustment-does-not-adjust-images/m-p/1250945#M44364 <P>I'm using ArcMap 10.8.2 to compile a 12-image mosaic of Worldview-3 1B imagery. Imagery is shifted by a pretty consistent distance in both x and y directions across the board, so I would imagine this should be a cut-and-dry problem. After creating a mosaic dataset of the tiles and orthorectifying using a geometric function in each tile's function chain, I use the&nbsp;<A href="https://desktop.arcgis.com/en/arcmap/10.3/manage-data/raster-and-images/block-adjustment-for-mosaic-datasets.htm" target="_self">block adjustment workflow</A>&nbsp;to compute tie points (n = 236) and add GCP's (n = 101).

I inspected the adjustment report but it indicates that no tie points or control points were used in the adjustment, and although it claims that 9 images of the 12 were adjusted, the "images not adjusted" list includes all 12 images.</P><P>Unfortunately my access to the imagery is private so I'm not sure that I can really make this a reproducible example.</P> Tue, 24 Jan 2023 19:06:06 GMT ChristianJohn 2023-01-24T19:06:06Z https://community.esri.com/t5/data-management-questions/block-adjustment-does-not-adjust-images/m-p/1250945#M44364 <P>I'm using ArcMap 10.8.2 to compile a 12-image mosaic of Worldview-3 1B imagery.
