OTF Reader Module
Global Mapper's OTF Reader Module is used by military personnel for mapping simulation exercises.
The OTF Module requires a separate OTF license purchased from Blue Marble Geographics. To purchase an OTF license contact firstname.lastname@example.org .
The Objective Terrain Format (OTF) is the runtime representation of the synthetic natural environment (SNE) for the US Army's One Semi-Automated Forces (OneSAF) simulation software. This file format contains four types of files, a database header file (.dhf), an OTF file (.otf), three network database files (.nw), and a single elevation map file (elevation_map). OTF data can be created via GOTS (Government off-the-shelf) and COTS (Commercial off-the-shelf) toolsets and from traditional GIS datasets, as supported within the toolsets.
The OTF integrates features and elevations together into a single-layered, polygon based representation using Irregular Triangulated Integrated Network (ITIN). This terrain is acted upon by other environment services to provide information to the simulation models to help them determine movement ability, speed, acquisition, and other capabilities needed to support the simulation activities and requirements.
