McElhanney is the oldest combined engineering, surveying and mapping company in western Canada. It is employee-owned, with its registered corporate headquarters in Vancouver, British Columbia. In 1910, land surveyor and engineer William Gordon McElhanney opened a one-room office on West Pender Street in Vancouver and set to work on his first survey of a small property in New Westminster. More than 100 years later, the McElhanney group of companies has multiple branches throughout western Canada and hundreds of employees. McElhanney's engineers, surveyors and mapping experts have worked on highways, bridges, ferry terminals, airports and railways, park boundaries and First Nations' community developments, oil and gas wells, power schemes and other resource industry infrastructure across B.C. and Alberta, including the Golden Ears Bridge roadway design, Treetops Adventure - Capilano Suspension Bridge, and the Trans-Canada Highway Twinning through Banff National Park. ==History== In 1912, when W.G. McElhanney surveyed the 124th meridian in B.C.'s interior, he was on horseback using an axe and a compass. Forty years later, his crews undertook one of the earliest uses of helicopters in B.C. for the development of the Kemano power project to support Rio Tinto Alcan's Aluminum smelter in Kitimat, B.C. Around the same time, they purchased the first MRA-1 tellurometer in B.C. The instrument would change the nature of surveying forever, as would the emergence of Doppler satellite surveying systems and subsequently, Global Positioning Systems, or GPS. McElhanney Land Surveys Ltd. started work in the oil patch of northeast B.C. and Alberta in the earliest days of the energy sector. One of the first partners in the McElhanney group, Fred Nash, undertook petroleum surveys in the Peace River region in the 1950s, and by 1977, McElhanney had opened offices in Fort St. John and Calgary. McElhanney continues to work extensively in the Alberta oil sands and in the Alberta and Saskatchewan oil patch generally, and in B.C.'s energy and mining industry. The mid-1980s were difficult days that saw the McElhanney group of companies go through major restructuring, but they weathered the storm successfully. McElhanney went on to play significant roles in B.C.'s Terrain Resource Information Management project, a multi-year aerial resource evaluation program in Indonesia sponsored by the Canadian International Development Agency (CIDA) and the boundary surveys for the Nisga'a Final Treaty Agreement. Today, using three $1.5 million Leica LiDAR (light detection and ranging) systems, McElhanney is using the latest airborne laser mapping techniques to produce everything from landscape profiles of watersheds and environmental monitoring data to emergency evacuation plans, municipal asset management, seismic control, deformation monitoring, route selection and stockpile volume assessment. The Mobile Mapping System - a truck mounted with sixteen digital cameras and loaded with high-end computers - creates accurate 3-D models of urban streets at a fraction of the cost of conventional survey methods. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「McElhanney」の詳細全文を読む スポンサード リンク
