Civil Geographic Information Systems

A geographic information system (GIS), or geographical information system, is any system that captures, stores, analyses, manages, and presents data that are linked to location.

GIS is a special-purpose digital database in which a common spatial coordinate system is the primary means of reference. Comprehensive GIS require a means of:

• Data input, from maps, aerial photos, satellites, surveys, and other sources
• Data storage, retrieval, and query
• Data transformation, analysis, and modelling, including spatial statistics
• Data reporting, such as maps, reports, and plans

LBE recognized the opportunity to apply this technology to initiate and develop a Bentley Map Software tool that can assist in the facilities management of complex infrastructure and technologically advanced environment such as petro-chemical and process plants.

Expertise and experience:

• Utilise Bentley Map together with Microsoft Access and SQL Server
• Access GIS with web browser tool
• Redraw input from existing drawings to CAD and link to GIS
• Convert data between different Geodetic and Local Coordinate systems, ie WGS 84 Ellipsoid (Hartbeeshoek Datum), Clarke 1880 ellipsoid (Cape Datum) and local Cartesian coordinates.
• Develop, administer and maintain the GIS data base
• Link existing and new electronic data to GIS
• Populate existing databases to the GIS and create linked objects to location

Typical Applications:

• Locating underground services, ie piping and electrical cables
• Map maintenance history of underground pipe lines and update with new data
• Utilise GIS to obtain building information for emergency response purposes
• Indicate legal responsible boundaries in terms of OHS Act appointments
• Linking infrastructure (ie buildings, roads and structures) at its as-built location to data tables or 3D Models
