GeoBase
Encyclopedia
GeoBase is a geospatial platform developed by Telogis. As Telogis was founded as a GPS tracking company, a particular focus was placed on high-transaction spatial rule processing for GPS coordinates reported by remote assets.

Core spatial functions

GeoBase also provides the core functionality common in street-mapping applications. These functions include:
  • Street Mapping
  • Reverse geocoding
    Reverse geocoding
    Reverse geocoding is the process of back coding of a point location to a readable address or place name. This permits the identification of nearby street addresses, places, and/or areal subdivisions such as neighbourhoods, county, state, or country...

  • Address Lookup (geocoding

  • Geofence

    A geo-fence is a virtual perimeter for a real-world geographic area.A geo-fence could be dynamically generated—as in a radius around a store or point location. Or a geo-fence can be a predefined set of boundaries, like school attendance zones or neighborhood boundaries...

  • Driving Directions
  • Route Optimization
  • Navigation

Spatial Analysis functions

GeoBase contains a spatial database

 structure that allows application to run spatial queries on both the underlying street data and dynamic data- such as vehicle location- that is added by the application.

Such a query would include: "Find all gas stations within 10 mi of vehicle xx"

Deployment models

GeoBase has developments for deployment in client server, ASP and AJAX

applications.

Newer versions of GeoBase include a technology called GeoStream. GeoStream enabled thin client applications (AJAX, .NET) to pull spatial data and functions off a central server while maintaining the performance of a thick-client application.
