public class LinearLatLonSet
- extends Linear2DSet
LinearLatLonSet represents a finite set of samples of
(Latitude, Longitude) in a cross product of two
arithmetic progressions.
This class exists to override valueToInterp (as defined in GriddedSet)
in order to handle Longitude wrapping.
The order of the samples is the rasterization of the orders of
the 1D components, with the first component increasing fastest.
For more detail, see the example in Linear2DSet.java.

java.lang.Object |
cloneButType(MathType type)
copy this Set, but give it a new MathType;

test for equality |
float[][] |
gridToValue(float[][] grid)
transform an array of non-integer grid coordinates to an array
of values in (Latitude, Longitude) |
java.lang.String |
longString(java.lang.String pre)
generates a longer string than generated by toString,
indented by pre (a string of blanks) |
float[][] |
valueToGrid(float[][] value)
transform an array of values in (Latitude, Longitude)
to an array of non-integer grid coordinates |
