Method Detail

setRegionOfInterest

void setRegionOfInterest(double lonMin,
                         double latMin,
                         double lonMax,
                         double latMax)

Sets the region of interest to return features for. After this method is called, the IlvMapFeatureIterator.getNextFeature() method should not return any feature which geometry is outside this area.

Parameters:

lonMin - longitude min in radians.

latMin - latitude min in radians.

lonMax - longitude max in radians.

latMax - latitude max in radians.

getLatLonBounds

Rectangle2D getLatLonBounds()

Returns the latitude/longitude bounds for the list of all geometries or null if such is not available.

Returns:

a rectangle enclosing all features.
