matlab.io.hdfeos.gd.gridInfo

Namespace: matlab.io.hdfeos.gd

Position and size of grid

Syntax

[xDim,yDim,upLeft,lowRight] = gridInfo(gridID)

Description

[xDim,yDim,upLeft,lowRight] = gridInfo(gridID) returns the size of a grid as well as the upper left and lower right corners of the grid.

Note

upLeft and lowRight are in units of meters for all GCTP projections other than the geographic and bcea projections, which will have units of packed degrees.

This function corresponds to the GDgridinfo function in the HDF-EOS library C API.

Examples

import matlab.io.hdfeos.*
gfid = gd.open('grid.hdf');
gridID = gd.attach(gfid,'PolarGrid');
[xdimsize,ydimsize,upleft,lowright] = gd.gridInfo(gridID);
gd.detach(gridID);
gd.close(gfid);
