OpenEarthTools has Matlab OGC functions wcs and wms for using the AHN(2) web services, which can be dowloaded here accessible after free registration for OpenEarth. We use WCS here so we can use our own colormap to highlight details (West of Netherlands is roughly between -5 for polders and +25 for dunes) rather then WMS which has a fixed colormap (needed to accommodate the full DEM range incl. Vaalserberg at +322m)
