What happens when you cache a map in Google Maps?
When you cache a map service, the server draws the map at a set of scale levels that you define and saves the images. When the server receives a request for a map, it’s much quicker to return one of these cached images than to draw the map again.
How to create a cached Map Service in ArcGIS?
In the Scale Settings window, click Load and choose ArcGIS Online / Bing Maps / Google Maps. Check the check box to Only display these scales when zooming. This will only allow you to view your layers and feature classes at the ArcGIS Online / Bing Maps / Google Maps scale intervals.
How often should I update my Map cache?
For maps that change only occasionally, tools are available to update the cache. To achieve optimal performance, you should cache as many layers as you can. You may find it helpful to make two maps and separate the layers that are appropriate for caching from layers that would not be feasible to cache.
What to do when a cache tile is not found?
This forces clients to use the tile handler to request tiles (instead of directly requesting tiles from the virtual directories) which retrieves missing.jpg (or missing.png) when a cache tile is not found.
What happens if you pick too many cache levels?
If you pick too many scales or pick scales that are unnecessary, you increase the cache creation time and required storage space. Conversely, your organization may have already determined a tiling scheme to use when caching. A tiling scheme determines certain properties of your cache, including which scale levels to create.
How to create fast map services in ArcGIS?
The best way to create fast map services is to cache them. When you cache a map service, the server draws the map at a set of scale levels that you define and saves the images. When the server receives a request for a map, it’s much quicker to return one of these cached images than to draw the map again.
