Live training seminar to demonstrate map caching strategies

During the past several weeks I've been working with Danielle Hopkins of ESRI Educational Services to prepare a live training seminar on ArcGIS Server map caching. The seminar is free and will be broadcast three times this Thursday, August 28 or you can watch it later in the seminar archives. This page has more information about how and when you can tune in to the seminar.

We prepared this seminar with two main goals in mind. First, we wanted to focus on caching strategies. The seminar will explain what map caching is and how to do it, but that is really just the beginning of successful caching. There are many things to think about when you create a cache, including how to design your map, how to choose a tiling scheme, where to create tiles, how to update the tiles, and so on. In this seminar, we'll show some best practices and how to implement them using, in many cases, new features available at ArcGIS Server 9.3. Hopefully you'll learn something new even if you've been caching for a while.

Second, we wanted to teach caching by showing it, so the presentation will include four demonstrations that might be similar to caching scenarios that you face. We'll show how to create a base map cache, how to create an overlay cache that gets updated nightly, how to create a partial cache that gets filled in on demand, and how to create a cache for a Web mashup. At multiple points throughout the presentation, we'll pause to take questions that you submit.

We look forward to seeing you on Thursday!

Update: The archived seminar is now available at http://training.esri.com/acb2000/showdetl.cfm?DID=6&Product_ID=931

# View seminar on Creating Map Services too!

The seminar was great. We are cross-training staff and it's very helpful. I wish I had something like this 2 years ago. I'd also recommend the seminar on creating map services by Danielle.

# Sharing Map Caches

We are a state agency so we have some very large caches. Our strategy is to create a basemap that can be used by multiple applications. We have a Development, Test, and Production environment. It seems like a waste of disk space to store the cache for our basemap on all three servers. Right now I'm setting up a 9.3 test server so I have three non-production servers. Is there a best practice for sharing cache between servers and services? I can understand keeping my production server isolated but wouldn't it be better to share the cached images on my Development and Test machines? Can my 9.3 map services point to my 9.2 cached images?

# re: Live training seminar to demonstrate map caching strategies

Thanks for your comments on the seminar! On several of the sessions we had many more questions than we could answer. We'll be addressing some of those soon on this blog and in the Web Help.

As for sharing caches, yes, you can share caches across machines. You just need to make sure that your machines can "see" the server cache directory (usually through a shared folder referenced by a UNC path) and that the location is designated as a server cache directory for each ArcGIS Server you use. Also, your services need to be named the same on each machine so that they match the name of the folder that contains your cache. 9.2 caches can be used by 9.3.

Informative post.Such seminars on map caching is very useful so it is good to publish news letters to members.

# re: Sharing Map Caches

Our Map Caches are growing! We are looking into purchasing SAN disk space. It seems silly to keep mulitple copies of the cache so our production and test boxes will share these caches. SAN is a less costly storage solution. I've learned that the SAN needs to be attached to a machine. Is there any known performance boost (or other reason) which machine the SAN should be attached to. We have a in a three tiered architecture - an AGS server (two machine/load balanced); one IIS web server (currently WebADF, but probably will become just IIS/JavaScript API), and one SDE server.
