I have 68 aerial jpegs that I would like to use in a Mosaic Dataset. They have not been georeferenced. My question is in regards to whether I should georeference them and then rectify and save them in a new folder where I will add later to the Mosaic Dataset, or create a geodatabase, drag all the jpegs into the geodatabase, georeference (rectify?), and then create a Mosaic Dataset inside the same geodatabase.

I noticed that the original file size of the jpegs is around 30 mbs and when rectified creates a 500 mb Tif! Will these sizes be too large to work with when added to a Mosaic Dataset?

I'm using ArcMap 10.1.

    YMMV, but we took all our rasters out of geodatabases to improve performance and prevent db bloat. – recurvata Oct 28 '14 at 18:45
  • In addition to @recurvata 's comment, do not rectify the rasters as long as you have no solid reason (please see this link), just update. – fatih_dur Dec 6 '14 at 13:09
