| Component2D | 2D Geometry object that supports spatial relationships with bounding boxes, triangles and points. | 
| Component2D.WithinRelation | Used by withinTriangle to check the within relationship between a triangle and the query shape
 (e.g. | 
| GeoEncodingUtils.Component2DPredicate | A predicate that checks whether a given point is within a component2D geometry. | 
| GeoEncodingUtils.DistancePredicate | A predicate that checks whether a given point is within a distance of another point. | 
| Geometry |  | 
| GeoUtils.WindingOrder | used to define the orientation of 3 points -1 = Clockwise 0 = Colinear 1 = Counter-clockwise | 
| LatLonGeometry | Lat/Lon Geometry object. | 
| Point | Represents a point on the earth's surface. | 
| Polygon | Represents a closed polygon on the earth's surface. | 
| Rectangle | Represents a lat/lon rectangle. | 
| SimpleWKTShapeParser.ShapeType | Enumerated type for Shapes | 
| Tessellator.Monitor | Implementation of this interface will receive calls with internal data at each step of the
 triangulation algorithm. | 
| Tessellator.Node | Circular Doubly-linked list used for polygon coordinates | 
| Tessellator.Triangle | Triangle in the tessellated mesh | 
| XYGeometry | Cartesian Geometry object. | 
| XYPolygon | Represents a polygon in cartesian space. | 
| XYRectangle | Represents a x/y cartesian rectangle. |
