'I would like to say that JC White Geomatics are relatively local to us and we have come across their work over the years which has always been of a very high standard. I have interviewed a couple of their staff for membership into the ICES and have found them a credit to the profession. The company seems to have a very contented workforce with the management investing heavily into training.'
