Elevation cache calculation - slow performance

Question asked by mik1971 on Jul 11, 2017

Hi,

 

We have very heavy elevation data >10 terabytes of *.asc files of 1 or 2 or 5 metres.

 

  • amount of ascii files about 40,000
  • ascii files organized in subfolders
  • size of an individual ascii file from 1 MB to 40MB.

 

The caching machine that we run 21 cores (from 24) generates only about one Gbyte cache per hour. It has been running more than two week as far.

We are looking to ways how to increase performance.

 

1. transform *.asc files before adding to Mosaic Dataset 

2. calculate overviews before calculating a cache

3. any other solution/ideas

 

Geoprocessing tool "Manage Tile Cache" (NOT ON THE SERVER), ArcGIS Desktop 10.5

Any help please.
