properties as they come from the WMS GetMap's FORMAT_OPTIONS vendor specific parameter.
The following parameters are parsed at construction time and held by an instance of this class:
- LOOKATBBOX: {@code xmin,ymin,xmax,ymax}
- LOOKATGEOM: {@code Geometry WKT}
- ALTITUDE: Double
- HEADING: Double
- TILT: Double
- RANGE: Double
- ALTITUDEMODE: String literal. One of
All of them are optional, and {@code null} will be returned by it's matching accessor method ifnot provided. LOOKATBBOX and LOOKATGEOM are mutually exclusive, and LOOKATBBOX takes precedence over LOOKATGEOM. Both LOOKATBBOX and LOOKATGEOM allow to define the area where the KML lookAt should be pointing at. If none is provided, GeoServer will use the aggregated lat lon bounding box of all the requested layers as it normally does.
