ElevationPool Retriving Multiple Elevations

[fcdalgic]

Hello,

I am using TMS Service to provide elevation data into my application. In this application there is a method that queries elevations from elevationpool by using envelope. Today, I noticed that, ıf I don't start the TMS Service and run the application only using cache files the query takes more than 4 minutes for total 239 coodinate, but if I run the service then it will take a less than a second. I am not sure if it is intended behaviour of server based elevation layer or a bug, just wanted to let you know.

Thanks.

It's possible that it is trying to query the service and timing out on connection requests, which can take a while.
You might want to activate cache-only mode in this case which will prevent any attempts at accessing the service.

You can test this by setting the environment variable OSGEARTH_CACHE_ONLY=1.

In code you can call setCachePolicy(CachePolicy::CACHE_ONLY) on the Map or the Layer in question.
Hope this helps.
