  • Why not just have the temporary rasters written to a RAM disk? Then you won't have to code the visibility op from scratch, which comes with its own risks and costs. Commented Nov 28, 2011 at 20:41
  • That sounds great. How would I go about doing that? Is that not what @Radar states is not possible in the answer below? Commented Nov 28, 2011 at 20:52

    You install a RAM disk on your system; details vary with the OS. Then you point the ArcGIS scratch folder at it. You could do almost as well using an SSD especially if your rasters are huge or if you don't have much RAM. Commented Nov 28, 2011 at 21:24
  • I like the RAM disk idea. An SSD is risky since they aren't great for constant read/write operations as you could wear it out quickly. Commented Nov 28, 2011 at 22:04

    A flash-based SSD will survive 1 - 5 million writes, @Radar, but DRAM SSDs won't "wear out" at all. Visit storagesearch.com for (lots) more info. Commented Nov 28, 2011 at 22:33
