SAMPLEXY_CURV_NRST(DAT_TO_SAMPLE,DAT_LON,DAT_LAT,XPTS,YPTS)

Returns data which is on a curvilinear grid, sampled at a set of (X,Y) points, from nearest location on XY curvilinear grid

Arguments:

DAT_TO_SAMPLE

Data to sample
(2D curvilinear data field)
 

DAT_LON

Longitude coordinates of the curvilinear grid
(2D curvilinear longitudes)
 

DAT_LAT

Latitude coordinates of the curvilinear grid
(2D curvilinear latitudes)
 

XPTS

X values of sample points
(1D list of points)
 

YPTS

Y values of sample points
(1D list of points, same length as XPTS

Result Axes:

X

ABSTRACT; length same as XPTS and YPTS
 

Y

NORMAL (no axis)
 

Z

Inherited from DAT_TO_SAMPLE
 

T

Inherited from DAT_TO_SAMPLE

Note: SAMPLEXY_CURV_NRST is a "grid-changing"function; its output grid is different from the input arguments.Therefore it is best to use explicit limits on the first argumentrather than a SET REGION command. (See this note on the context of variables passed to functions.)
