The first ever Worldwide Trimble Mapping & GIS conference was held in San Francisco on the 18th to 21st of April. It was attended by some 300 Trimble Dealers and Business Partners from around the world. The conference offered a range of informative courses on various GPS and business related topics. Trimble presented quite a few new products during the conference giving attendees the opportunity to see the new technology and learn about it from the people who actually developed it.   Subfoot Accuracy Trimble has launched the first mapping grade sub-foot GPS receiver – ProXH. Alongside ProXH, the new submeter receiver ProXT was also presented at the conference. Both receivers come with an integrated L1 antenna and are capable of submeter accuracy with real-time differential correction (their real-time capabilities are similar to those of GeoXT).   To request the GISDATA Review issue Fall 2005 / Winter 2006 in pdf format (2 MB) be sent to you by e-mail please click here.
