public interface Projection
Projective geometry transformations from (lat,lon) to (x,y) on a projective cartesian surface. We use the java.awt.geom 2D classes to represent the coordinates on the projective plane.
Method Summary | |
---|---|
boolean |
crossSeam(ProjectionPoint pt1,
ProjectionPoint pt2)
Does the line between these two points cross the projection "seam", which is a discontinuity in the function latlon <-> projection plane |
boolean |
equals(Object proj)
Check for equality with the object in question |
String |
getClassName()
The name of this class of projections, eg "Transverse Mercator". |
ProjectionRect |
getDefaultMapArea()
Get a reasonable bounding box in this projection. |
String |
getName()
The name of this projection. |
List<Parameter> |
getProjectionParameters()
Get parameters as list of ucar.unidata.util.Parameter |
ProjectionPoint |
latLonToProj(LatLonPoint latlon,
ProjectionPointImpl result)
Convert a LatLonPoint to projection coordinates. |
String |
paramsToString()
String representation of the projection parameters. |
LatLonPoint |
projToLatLon(ProjectionPoint ppt,
LatLonPointImpl result)
Convert projection coordinates to a LatLonPoint. |
