GIS Utility Mapping at George Bush Intercontinental Airport (GBIAH)

S&B Infrastructure, Ltd. (S&BI) provided field data collection, GIS database development, and data repository services to identify and map all underground telecommunication cabling and appurtenances for George Bush Intercontinental Airport. S&BI acquired data via field surveys using Global Positioning Systems (GPS) and developed and populated an ArcIMS repository with GIS referenced information. Documentation included existing outside plant communication ductbanks, manholes, handholes, associated communication cables, existing direct buried communication cables, termination panels, splice enclosures, gates, signs, building access points, fiber and copper cables (including in-use and abandoned) for the entire IAH campus including:

 

  •  Fuel Farm

  • AirCargo

  • Central Plant

  • Airport Services Complex

  • Rental Car Facilities

  • Fire Stations

  • Administration BuildingNorth/South/West vaults

  • Tenant Hangars

 

Inside plant riser and horizontal cabling were traced for identifying the function of the cable (i.e. access control, fuel monitoring, telephone/data, etc.).

 

S&BI gathered as-built drawings from airport staff and collected field data attributes in GIS (using ArcPAD and a Pocket PC). The data collection included using Leica GS50 GPS receiver with real time data correction collecting points, lines and polygon features. Code lists were created for data attribute tables with Leica GIS DataPro software. Interior elevation detail drawings for each manhole were prepared describing number and type of cables in each manhole and electronically linked to a GIS basemap. Manhole dimension/ elevation information was overlaid within QuickTime Virtual Reality (QTVR) digital panorama photographs of the manhole interior. S&BI provided digital photographs and QTVR panoramas of each manhole (exterior and all interior faces) electronically linked to the GIS basemap. All files were spatially integrated and crossed-referenced for intuitive user retrieval, display, and printing/plotting. A traditional two-step process was therefore reduced to just one step resulting in both time and cost savings.

 

All project documentation was entered into an ArcIMS database that included aerial photography. Using Internet Explorer, Houston Airport System and its consultants accessed the ArcIMS website to view daily updates, coordinate project tasks, perform QA/QC, track work progress, and provide access to useful telecommuni-cation data in support of ongoing projects. SBI also developed GIS, GPS and Data Collection Standards
