Question 9

An ArcGIS user has built a mosaic dataset using 25 rasters. However, upon adding the mosaic dataset to a blank map, the user finds that all rasters are NOT displaying. To troubleshoot the issue, the user zooms to the source resolution of one of the tiles and notices that the raster displays at 1:107000 but NOT at 1:997000.

Which tool needs to run to allow display of the rasters from 1:107000 to 1:997000?
