Description

In ossimElevationDatabase, line 116 (​http://trac.osgeo.org/ossim/browser/trunk/ossim/src/ossim/elevation/ossimElevationDatabase.cpp)

If the evelation cell file does not exist on the filesystem, the status is not recorded in cache, and the unkown file may be looked up each time elevation is requested, leading to filesystem overload.

Holding on this. Concerns:

If a cell is added it won't be picked up without a restart of the manager. Perhaps use a time tick. Talked to Garrett about this and he has some ideas.
