Integrating CAD and GIS
By Spatial Source on 13 May, 2010PETER KINNE The concept is familiar: take data from one environment to another without losing integrity, information or intelligence. However, the integration of CAD and GIS environments continues to be an issue, especially for local government and agencies where information from designers needs to be placed in its true geographic context.

The Future of GNSS
By Spatial Source on 13 May, 2010WILLIAM GIBBS At least one possible future for the delivery of high-accuracy services from global navigation satellite systems is becoming clearer as time passes. A large number of networks will be available. They will be operated by private enterprise. Surveyors and others in need of centimetre-level positioning have much to look forward to, although it […]
Satellite-Based Augmentation Systems
By Spatial Source on 13 May, 2010ROBERT LORIMER America has the wide area augmentation system (WAAS), Europe the European GNSS overlay system (EGNOS), Japan the multifunction satellite augmentation system (MSAS) and India is launching its GPS-aided Geo-augmented navigation (GAGAN) system. They are all satellite-based augmentation systems (SBAS) and are already delivering improved accuracy and integrity for GPS users over much of […]
