Creating a Ortho Imagery Mosaic for Use in CAD

Hello,

We've been tasked with recreating a new ortho imagery set after migrating hardware. I believe I understand one way to create a mosaic dataset that can be then published as an image service, but attempting to create the ortho imagery dataset (via Create Mosaic Dataset then Add Rasters to Mosaic Dataset) had run the process from late Friday afternoon to Monday morning with no indication of the status of the process (no percentage of the process run or anything). I could not tell if it might have finished in 1 hour or 1 week.

I was told of a Repair tool that *could* be used to redirect the source location of the TIFF files from the old location to the new source location, but I intended to have a backup available in case that process went sideways so I prioritized creating a new mosaic dataset instead (it would also be good practice for creating similar mosaics in the future).

The dataset I wish to use has 5976 separate TIFF files (around 300MB apiece) so I wasn't surprised it was taking a while to process, but I am curious if anyone has any ideas of how to expedite/improve the process (ie different settings) if they have experience working with a mosaic made of a similar amount of TIFF files (or even if they have an estimate of how long that process might take). I wasn't around when the original mosaic was created and creating a new mosaic of this size is a new experience.

These will be used as a mosaic as an ortho imagery layer for our CAD (computer aided dispatch).

Thanks,

Cody

Hi @CodyLyons

 

I'm also in a similar situation in which I have to to load many raster files to a mosaic raster and I haven't found any faster and secure way other than uploading the data through 'Add Rasters to Mosaic Dataset'. Maybe more experimented users can give us a new insight. 

 

On the Logging topic, you can know how much a process lasted by going into 'History' (in 'Analysis' tab) and looking at your recent tools run on your .aprx project. There you can see the start and ending times of your processes. 

 

You can also look what Loggig options you currently have, as there are 3: 

  • Write geoprocessing operations to Geoprocessing History: The example I told you about
  • Write geoprocessing operations to XML log file: A XML Log File is created in %AppData%\Esri\ArcGISPro\ArcToolbox\History 
  • Write geoprocessing operations to Dataset Metadata: You can right click on a Layer, click on 'View Metadata' and watch the previous changes

 

You can find more information in the following links:

Hope this helps!
