Namespace: matlab.io.hdfeos.gd

Read region of interest from field

Syntax

data = extractRegion(gridID,regionID,fieldname)

Description

data = extractRegion(gridID,regionID,fieldname) extract data from a subsetted region.

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

Examples

Define and extract a region of interest between 20 and 50 degrees latitude and between -90 and -60 degrees longitude.

import matlab.io.hdfeos.*
gfid = gd.open('grid.hdf','read');
gridID = gd.attach(gfid,'PolarGrid');
cornerlat = [20 50];
cornerlon = [-90 -60];
regionID = gd.defBoxRegion(gridID,cornerlat,cornerlon);
data = gd.extractRegion(gridID,regionID,'ice_temp');
gd.detach(gridID);
gd.close(gfid);
