AMSO M&S/C4ISR Interoperability Experiment
In 2000, an initial experiment in importing gridded terrain elevation data from SEDRIS 2.5.2 transmittals into JMTK was performed:
- A new internal JMTK gridded data format was created that was expected to provide faster retrieval than the native DTED format
JMTK STF Import Process:
- Recognize SEDRIS transmittal file(s) within specified directory
- Find Property Grid objects containing terrain elevation data
- Extract the terrain elevation data from the Property Grid objects
- Create file(s) in the new JMTK internal gridded data format
- Create JMS metadata and index files
JMTK STF Retrieval Process:
- Retrieve terrain elevation data from JMTK internal gridded data format
JMTK import & retrieval of one DTED Level 2 cell in Korea (25MB):
- DTED: Import 5 sec Retrieval 3.04 sec
- STF 2.5.2: Import 342 sec Retrieval 3.37 sec
Results:
- STF import was FAR slower than DTED import (due to required extra work)
- New internal format did NOT provide faster retrieval than native DTED
