matlab.io.hdfeos.gd.defPixReg

Namespace: matlab.io.hdfeos.gd

Define pixel registration within grid

Syntax

defPixReg(gridID,pixRegCode)

Description

defPixReg(gridID,pixRegCode) defines whether the pixel center or pixel corner is used when requesting the location (longitude and latitude) of a given pixel. pixRegCode can be one of the following values.

'center'Center of pixel cell
'corner'Corner of pixel cell

If this routine is not invoked, the pixel registration is 'center'.

This function corresponds to the GDdefpixreg function in the HDF-EOS library.

Examples

Define a grid with pixel registration in the center.

import matlab.io.hdfeos.*
gfid = gd.open('myfile.hdf','create');
gridID = gd.create(gfid,'PolarGrid',100,100,[],[]);
projparm = zeros(1,13);
projparm(6) = 90000000;
gd.defProj(gridID,'ps',[],'WGS 84',projparm);
gd.defPixReg(gridID,'corner');
gd.detach(gridID);
gd.close(gfid);
