Hi Paul, no, there's no support for ISO WKB yet. We still stick to http://home.gdal.org/projects/opengis/twohalfdsf.html I can imagine we could have exportToISOWkb() method in OGRGeometry*. Or we could add an extra boolean argument bISOWkb to the existing exportToWkb(). Not sure about WkbSize() : does the size of ISO WKB blobs differ from the unofficial WKB ?
