Introduction
Compact Terrain Database (CTDB) is an optimized run-time format used by the popular ModSAF and OneSAF applications. A compiler that converts SEDRIS terrain databases to the CTDB format has been developed, and a complementary application that converts existing CTDB databases to the SEDRIS Transmittal Format (STF) is in testing. The SEDRIS to CTDB compiler gives users the ability to access a wider range of databases through SEDRIS. The CTDB to SEDRIS conversion allows the resulting STF data to be analyzed or visualized using a variety of SEDRIS-based tools. This tutorial covers the capabilities of both applications. The tutorial on the SEDRIS to CTDB conversion covers the basics of the CTDB format, what the compiler expects to find in a SEDRIS transmittal in order to produce a useful CTDB database, and the variety of terrain data types that can be converted to CTDB. The CTDB to SEDRIS portion of the tutorial covers the conversion process and the mapping of CTDB data to STF, and how SEDRIS-based analysis and visualization tools are utilized to examine the content of CTDB databases.
