Laser-Scan announced that the latest version of Radius Topology delivers advanced spatial data management for 2.5d. This means that Radius Topology's capabilities in the automatic correction of data inconsistencies are now available to customers whose data includes a height (or "z") value.
Following the launch of Radius Topology, Laser-Scan has established a strong partner channel. A number of these partners handle height data associated to node points in their existing solutions. This is termed 2.5d by most of the geospatial industry. As a result of requests from the partner channel Laser-Scan has developed version 2.5 of Radius Topology, currently in its beta program.
Laser-Scan's Radius Topology is a dynamic topology management layer that was initially delivered on the Oracle9i platform. This means that Radius Topology acts as a "gatekeeper," only allowing clean, accurate data into the database. Inconsistent data is automatically corrected, within the bounds of user-defined rules and without any significant disruption to the existing IT workflows.
