readData

public GridAsPointDataset.Point readData(GridDatatype grid,
                                CalendarDate date,
                                EarthLocation location,

                                  throws IOException

Reads data for the given point (earthlocation) and if bounded is true returns data for the closest point within the grid, for points outside of the grid

Parameters:

grid - read data from here

date - at this time

location - EarthLocation, if altitude is NaN assume that is 2D point

bounded - if bounded, location must be in grid cell; otherwise get nearest grid point to location

Returns:

the location and data value

Throws:

IOException - on bad stuff

main

public static void main(String[] args)
                 throws IOException

Throws:

IOException
