Hi, I have some lidar DTM in mm that needs to be converted into meter keeping the Nodata value as it is (i.e. -9999). Converting them to M is fine but it changes the NoData value and causes problem when I tried to create Mosaic dataset overview . Could someone please help me on this?
Many thanks,
Rajib

You do not need to run the raster calculator to create a copy of each file with Z value in Meters! The Mosaic Dataset is designed to work with your *original* data and process all of it together to ensure everything is done the same (and avoid creating extra files). If you add your original data to the Mosaic Dataset, you can add an Arithmetic function onto the entire collection to rescale from millimeters to meters.
Then in the properties of the mosaic dataset, define your nodata value. This will make maintenance much easier...
