G.I.S. and Data Conversion
At Meridian, we provide services to all sectors that require GIS services – from urban planning to resource planning and management. Whether you require custom maps for presentations or large-scale data information management, our knowledgeable and highly qualified staff can meet your GIS needs. Using leading edge technology and state of the art equipment, we have completed projects, throughout North America, for major pipelines, gas and oil exploration, sea ice tracking, wildlife and natural resources management support, topographic and cartographic mapping, and geographic image analysis.
With the use of ESRI and Auto DESK products, such as Civil 3D and MAP 3D, we can provide accurate and detailed topologically structured data for Geographic Information Systems use.
We are also equipped to provide GIS consulting, cadastral mapping, scan digitizing, thematic mapping, data conversion, data integration and data maintenance.
Meridian can provide hardcopy and digital colour products and can transfer digital data to and from clients in a number of different spatial data exchange formats.
GIS data conversion projects
Pipeline GIS data conversion
Meridian Surveys Ltd. has been very active, over the past ten years, in the conversion of pipeline data into Geographical Information Systems (GIS).
As large pipeline companies have switched over to GIS systems to help manage their large pipeline systems, a need has arisen for older existing pipeline data to be converted into GIS data. The existing pipeline data varies from old paper pipeline alignment sheets, fabrication drawings and bill of materials, to a mixture of hard copy plans, spreadsheets and even ISAT and PODS databases.
The GIS consists of two parts
An accurate geo-referenced and controlled pipe centerline.
This is created by traversing in the pipe centerline into a known coordinate system such as UTM, using as-built surveys data, survey control points, legal plans and high resolution satellite imagery. The pipe centerline must have control points at the bends and known crossings to hold chainage values at those spatial locations.
Pipe attributes in a database
The attribute data is captured from hard copy drawings, field notes, spreadsheets, digital drawings and databases and re-formatted into the client's specific GIS database tables.
- BENDS
- WEIGHTS
- CAD_WELD
- CASING
- COATING
- CONCRETE COATING
- CROSSINGS
- DEPTH_OF_COVER
- FITTINGS
- GIRTH_WELDS
- PIPE CHARACTERISTICS (O.D., WT, GRADE, MANUFACTURER ETC.)
- REPAIRS
- VALVES
- TEST STATIONS
- FACILITY SITES
- CATHODIC PROTECTION (GROUNDBEDS, RECIFIERS, ANODES)
