Hello, Question 1: Limit a cached area by using a shapefile. Does map server give us the ability to limit the extent of a cache using a shapefile? I know we can set up a rectangular grid for the extent. However, I would like to make sure tiles are not generated beyond the area of interest.
Question 2: Can we or should we adjust the Google Compatible 3857 grid? I realize I should start supporting the 3857 grid for some applications. However, I also don't see the need to cache the entire world. What is the best approach to build a cache for a small area that is in the same tile schema that Google, Bing, and ArcGIS use? *Is there a tool available to calculate the appropriate rectangular grid for an area of interest? *Similar to question 1, can we limit the cached area using a shapefile? Question 3: Are there any considerations if multiple grids use the same projection? Are there any considerations if multiple grids use the same projection. For example, will there be a problem if we have a cache for County A, County B, and County C all using the 3857 grid? After adding the WMS layer I noticed that the dialog for ArcMap-->WMS Layer-->Change Coordinate System will list every projection configured in MapCache even if that particular projection applies to a different county. *Will Mapcache work with multiple grids using the same projection? *Am I better off setting up several mapcache aliases such as https://jingthegisguy.wordpress.com/2015/05/06/mapcache-the-basic-settings/? Thank You! Sincerely, Mark Volz, GISP
