readData

public GridAsPointDataset.Point readData(GridDatatype grid,
                                         CalendarDate date,
                                         double ensCoord,
                                         double zCoord,

                                  throws IOException

Reads one single data for one point. Takes the ensemble and elevation coordinates allowing them to be < 0 and in that case they'll be ignored.

Returns:

Point matching lat/lon for this grid

Throws:

IOException

readData

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