Tactical terrain data-spatial data for the 1990s

摘要

Since its recognition as an Army requirement, tactical terrain data (TTD) has evolved into a joint service resource with great potential for support of land combat operations. TTD, currently in prototype form, contains digital terrain elevation data (DTED) at one-arcsecond resolution as well as feature information equivalent to an enhanced 1:50000 scale tactical terrain analysis database. It also contains selected features from the 1:50000 scale topographic line map and combat chart. Prototype development and evaluation are described.
