- Petroleum Industry.
The following lists a few projects that Tekmap has working on:
Beaufort Shelf and Slope Multibeam Mapping Project
Since 2001, Tekmap Consulting, has worked with the Geological Survey of Canada on the multibeam mapping project of the Canadian Beaufort Shelf and Slope. This project has involved processing Simrad EM3000 multibeam data collected from various platforms. Products generated for this project include:
- Color-shaded bathymetry and backscatter.
- 3D Visualization and fly-through animations of select features.
- Ice scrour tracking and analysis using specialized software developed by Tekmap.
- Data comparison from repeat surveys to measure changes over time.
This project is ongoing.
Interactive Public Kiosk Software Development
The Interactive Kiosk Software was a multi-stage project developing software for public kiosks used at the Bedford Institute of Oceanography in Dartmouth, Nova Scotia. The basic setup of the kiosk included a touch screen monitor and a second large format TV.
The original kiosk software consisted of a Web based interface using HTML for touch screen navigation. Output to the TV included movies, images, and other Web content.
The current kiosk software includes a custom interface to the NASA World Wind viewer. An interactive globe displays in the touch screen and appears on the TV. This project is ongoing.
Multibeam Data Analysis — Black Point Dredged Material Disposal Site
The Black Point Disposal Site project, completed for Environment Canada, examined multibeam data collected between 2003 and 2009. The data comparison was needed to produce quantitative results and recommendations on the status of the disposal site.
Fathom Five National Marine Park Multibeam Mapping Project
Since 2001, Tekmap Consulting has worked with the Geological Survey of Canada, Parks Canada, and the Canadian Hydrographic Service on the multibeam mapping project at Fathom Five National Marine Park. Fathom Five is Canada's first national marine park located in Georgian Bay, north of the Bruce Peninsula. The survey area includes several points of interest including: shipwrecks, bedrock pop-ups, glacial features, and large sections of the Niagara Escarpment. Products generated for this project include:
- Color-shaded bathymetry and backscatter.
- 3D Visualization and fly-through animations of select features.
- Fusion with other map products such as sidescan.
- Backscatter training to map bottom morphology.
- Digital elevation model (DEM) building using multibeam and existing elevation data from various sources.
- Data comparison of multibeam bathymetry and backscatter to ROV and towed camera data.
The Bermuda Sea Level Project
From 2003 to 2005, Tekmap Consulting worked on the Bermuda Sea Level project. This was a joint project with the Geological Survey of Canada and the Bermuda Underwater Exploration Institute (BUEI). Part of this project included mapping the shallow waters around Bermuda in areas with known date markers (e.g. drowned cedar forest). The SHLS was used for this mapping, which provided accurate depths for low stand sea level.
Sidescan & Backscatter Interpolation — Burlington, Ontario
This project involved processing and interpolation of sidescan and backscatter data collected at Burlington, Ontario using a Benthos C3D Interferometric Sidescan. The emphasis of this project was to produce a substrate classification based on the processed sidescan and backscatter data.
Geoscientific Mapping of the St Lawrence Estuary
The St Lawrence Estuary project was to combine multibeam data collected from multiple surveys on the St Lawrence Estuary from 1997 to 2007. The multibeam data were Simrad EM1000 and Simrad EM3000 data collected from various platforms. The emphasis of this project was to produce a high quality normalized backscatter map for the survey area.
Various SHLS Surveys
Tekmap Consulting has used the Sync Humminbird Logging System (SHLS) on a number of surveys including:
- Bermuda Sea Level Project (multi-year).
- Tuktoyaktuk Harbour (Beaufort) survey.
- Ox bow lake and Red River survey in Shreveport, Louisiana.
- Bedford Basin Engineering survey.
- Data comparison repeat survey at Pointe Penouille in Baie de Gaspé.
-
Tailings pond and abandoned pit engineering survey.
Search for Swissair Flight 111
In September 1998, Tekmap Consulting provided on site assistance for the search for Swissair Flight 111 in St. Margaret's Bay, Nova Scotia on board the C.S.S. Matthew.
