Trimble Introduces GPS Analyst Extension for ESRI's ArcGIS

SAN DIEGO, Calif., Aug. 12, 2004 --Trimble (NASDAQ: TRMB) today introduced a software extension to ESRI's popular ArcGIS® software--Trimble® GPS Analyst. Developed in collaboration with ESRI®, the GPS Analyst extension allows mapping and Geographic Information System (GIS) professionals to directly process GPS data inside the ArcGIS software environment. ArcGIS is an integrated framework of software for the creation, analysis, display and management of GIS data.

The announcement was made today at the 2004 ESRI International User Conference

The GPS Analyst extension improves data accuracy and field-to-office workflow by tightly integrating GPS location data with the GIS database. With the extension's ability to differentially correct GPS data directly inside ArcGIS, Trimble GPS Analyst can improve the accuracy of GPS positioning from 10 meters to 50 centimeters, depending on the GPS receiver and environment.

"GPS Analyst is seamlessly integrated with ESRI ArcGIS software," said Alan Townsend, vice president and general manager for Trimble's Field Solutions Division. "The extension provides powerful tools for working with GPS data inside ArcGIS, which translates to greater efficiencies for our customers."

"ESRI has been working closely with Trimble to develop an extension for ArcGIS," said Jack Dangermond, president of ESRI. "GPS Analyst will perform differential correction computations and related processing to support an end-to-end GPS workflow."

Productivity is improved because GPS data can be checked straight from the field into the GIS, eliminating unnecessary file conversions. And, since the GPS data is stored directly in the geodatabase, it can be overlaid and analyzed with the other GIS layers. In addition, the GPS Analyst extension is fully open, customizable and extendible using ArcObjects, allowing developers and customers to build workflow and applications that meet their specific needs.

The Trimble GPS Analyst extension is expected to ship in the fourth quarter of 2004. It will be available to purchase from Trimble dealers and business partners, and from ESRI.
