.flt Interior
Geometry OpenFlight files describing the geometry of the interior
of geotypical models for a given level of detail. The value of Component Selector 2 is the file number.
Multiple files are used when the complexity of the interior justifies using more than one file.

.xml Descriptor Provides the metadata associated with a GTModel.
See section 6.14, Metadata, for a description of the content.
NOTE: A model descriptor includes a Composite Material Table for the exclusive use by its
corresponding model geometry datasets above. This CMT is not to be confused with the GTModelCMT and
GTModelInteriorCMT datasets below.

Composite Material
Index Each texel is an index into the associated Composite
Material Table dataset 505 and 513 below. CS2 is the layer number.

.tif Composite
Material Mixture
Each texel indicates the proportion between 0.0 and 1.0 of the composite material found in the
corresponding material layer. Component Selector 2 is the layer number. When the texels are of integral
types, they are scaled to the range 0.0 to 1.0.

Material Table
The Composite Material Table is associated with Material Textures; it contains the definition of the
composite materials referenced by the model material datasets above. Its format is as specified in section

.shp .shx
.dbf RCS
Signature The Shapefile containing the Radar Cross Section of a
geotypical model as described in Chapter 7. 017..032
.dbf RCS Class
Attributes The class-level attributes associated with the RCS
Signature file as described in Chapter 7.
Note 1: For GTModelSignature dataset, CS1 refers to the “RCS Frequency” and is used to indicate at which frequency in MegaHertz the dataset was generated for. The value of CS1
represents a power of 10 of the frequency and ranges from 1 to 999. The range of frequencies that can be represented is from 10
1
MHz to 10
999
MHz. Note 2: For GTModelSignature dataset, CS2 refers to the “RCS Polarization Type” and is used
to indicate how the electromagnetic field is polarized at transmission and reception by typical Radar. The value can range from 1 to 16 for the instanced-level attributes and from 17 to 32 for
the class-level attributes.
