Hello fellow ESRI Users.
Oracle 11.2, SDE 10.2.2, ArcMap 10.2.2
Recently, I have been experimenting with Raster Mosaic Datasets with Overviews and I am trying to understand the relationship between MINPS/MAXPS and scale. I have read the ESRI documentation:
Hopefully you can view the attached jpg.
Here the first two Images kgrs0001 and kgrs0002 are the original tifs - the rest being the Overviews generated by taking the Default Settings in the ESRI Tools.
Question 1: Is the MINPS and MAXPS calculated incorrect? I assume 0 - 20 would be better than 0 - 100? And I should use the "calculate cell size ranges" tool?
Question 2: Follow on from 1, in the MINPS and MAXPS columns there should be no overlaps of values i.e 0 - 20, 20 -40, 40 -80 etc - correct?
Question 3: I know the equation about calculating the cell size to scale when viewed in ArcMap. If in the attached example - if I zoom in with ArcMap to a scale of 1:1000 I assume I am viewing the original tifs - is there anyway of checking if I am using orginal tif or overview?
Question 4: if we only view the data at 1:1000 scale - there is no need to build overviews?
Hopefully someone can help my understanding further.
