ABSTRACT
When we review positional data, we often need to create a static position to represent a specific location. This location could be a city, an installation, or even just a place. In STK, this object is modeled as three different objects: the Target, Facility, and Place objects. However, these three objects are essentially the same in structure and form. The feature geometry in all is a point feature. Besides the icon that represents the objects, the only real difference is the STK Object extension: the Target is a *.t object, a Facility is a *.f object, and a Place uses a *.plc object extension. The Target, Facility, and Place objects all represent a single fixed point on a central body. They may represent a targeted position based on latitude, longitude, and altitude, or they may represent a city or facility or simply a fixed position in time and space. The methods for the objects are the same and utilize the same databases, files, and properties (see Figure 6.1).
