This class will allow for the addition of features and their geometry for inclusion into the collision world. Basic assumptions as to soil type will be made in that if it is below 0 it will be considered a water surface and above ground a hard packed surface. Each area will be transformed into it's own collision object. Point objects will be gatherd up and once the convertToGeometry routine is called, they will be triangulated and transformed into polygons.

Queries DtFeatureToGeometryConverter::myQueries

protected

Queries that can be used to perform specified functions. These queries will be used by particluar subclasses in order to refine searches. Keywords are specific to the particular subclass. For example, the S57 loader will use an "COVERAGE_AREA" search to refine the area to include when looking for feature objects. For queries that can be applied as refinement for what to create geometries from, they should be called "QUERY<N>" where N is a number of a query. Those queries will be performed in order.
