Hi,
Does anyone know how to write a TiledMapService and a Map Tiles pregeneration utility by using Service Edition 3.0? The Desktop Edition or Web Edition applications can comsum the TiledMapService. The TiledMapService should look like a ArcGIS Server 9.3 TiledMapService. (You can use ArcCatalog create a TiledMapService and use ArcView or Flex/Javascript/.Net ADF web application to consume it)
Thanks.
Kevin,
We are currently working on this. We actually already had some tiling stuff but our various products implemented it slightly differently. We decided to unify the tiling system and to make it easy to use it across all of our products and provide some griding primitives to make things easier for you as well. The plan is to have a set of API’s that allow you to generate the tiles. Next we are creating a WMS, Tile Server, WFS products that can publish the tiles. The final piece we really already have which are WMS layers built into our various version. We will need to create a TileServerImageLayer to be able to pull those down. Though we are not building it now we also want to have a end user GUI tool to help generate or re-generate portions of the cache. If you have any suggestions on this while we are developing it please let me know.

Is the plan to have this service follow the (still in comment period) OGC Web Map Tiling Standard?

John,
Absolutely. This standard is much more useful for scalability as WMS expects you to draw ever tile from scratch. Actually we plan to adding a cache to our WMS implementation however it is only useful if you stick with WMS clients that fetch data at predictable scales. The WMTS is better as it defines the scales that exist up front and can then cache aggressively.
There is also this pseudo standard out there from OSGeo. It looks about the same as the WMTS however it is more simple and straight forward. They describe in two pages what it takes OGS one hundred and eight pages.

If you have any suggestions, comments, demands now is the time as we are in the planning pases now.
