Purpose

At the core of the Battlefield Acoustic Tactical Technology Software is the locating of objects in the world.

However, just knowing the latitude and longitude does not intrinsically complete the information that is required. We need to move these objects in 3-Space, rotate, and calculate various geometric relationships.

This module contains the elements required to do so. It also provides access to two datasets that are central in acoustic propagation:

• DTED - a standardized military format for the Digital Elevation Model (DEM). The Digital Terrain Elevation Data provides the BATTS code the ability to determine the elevation of the ground beneath the latitude/longitude
• Land Cover/Land Use - This is again a standardized format that defines the type of ground at a latituide/longitude. It is core to determining the surface properties for the excess ground attenuation models.

This module also provides an interface that knows how to convert the geodetic latitude/longitude pair to the geodesic Universal Transverse Mercuator projection and through the importing of the CartesianCoordiantes provides access to the distance, angles, and move functions.
