For me this is the difference between Mosaic Datasets being extremely powerful and versatile things that really transforms the way we handle large tiled datasets...and them not being that at all because I can't share them as part of GIS package because the end user will get broken links. It's sometimes ok to ask the end user to repair paths when they receive the GIS package, but (a) it's not great if they are a client and (b) if they don't have a standard licence, they can't repair links.
It would be great if you could make this fix ESRI.
I notice now at least in ArcGIS Desktop 10.5, in ArcMap/ArcCatalog if you right-click a mosaic dataset, there's an option under Remove - Reset Relative Path, but not clear what it does and couldn't find any documentation on it. What does this mean? Are relative paths now supported in mosaic datasets, if not, please make it so! Thanks.
It's 2020....and still no ability to set the properties of a mosaic so that paths to the source imagery are relative.
i.e.
Folder
\Some_Geodatabase.gdb
\Derived_Mosaic
\Source_Mosaic_1
\Source_Mosaic_2
\Some_Geodatabase.Overviews
\SourceImagery
\ImageryForSource_1
\Image1.tif
\Image2.tif
etc
etc
\ImageryForSource_2
\Image1.tif
\Image2.tif
etc
etc
The attribute table in the source mosaics would appear like
.\SourceImagery\ImageryForSource_1\Image1.tif
.\SourceImagery\ImageryForSource_1\Image2.tif
It would still be very good to have the ability to use relative paths in Mosaic datasets. As far as I'm aware relative paths are possible in everything so it doesn't make any sense that relative paths are not available in Mosaic datasets.
Just added kudo #50 this morning on this - I ran into this during what I thought would be a straightforward migration of a large mosaic, and ended up having to rebuild the whole thing. So yes. We definitely need ability to make mosaics more portable through the use of relative paths.
