I have 9GB of .tif files. They are all rectangular, adjacent, and are a series of separate .tif files.
I have ArcGIS Server 10.1 Advanced. I do not have the Image Service Extension.
Here is my current set up, with regards to imagery:
- I have mosaiced the.tifs into a .sid file. I have published it from an MXD as a Map Service. I then cached it with 5 scales; 1:288, 1:750, 1:1000, 1:2500, and 1:5000. It works fine, but as is usual, my users want something faster and better.
- The imagery is 3in res RGB.
- Without Caching, the image is very slow; all the users of our Map Viewer complain how slow it is. But, with caching, they need to see down to 25 scale, which they cannot do at the moment. That means I need to create a 11GB Cache. Something that does not seem to be an option since ArcGIS Server does not process caches this large. I have tried only to see the caching process stop after 5 days.
My question:
Will creating a File Geodatabase and building a Raster Catalog and/or Raster Mosaic from the .tif files; then publishing as an Image Service improve performance without the need for Caching?
I have tried setting up a Raster Catalog and Raster Mosaic in a File Geodatabase from Desktop 10.1 and it appears to refresh much faster than the original .tifs and the .sid file.
