Aerial surveying is a method used in geomatics to collect information using aerial photography or through electronic magnetism which makes use of remote sensing technology. Ultraviolet, gamma or infra red rays are often used in this type of surveying. Therefore there is need for airplanes and helicopters to be used for the survey work.
Aerial survey is very different from satellite imagery. Aerial survey results in higher quality output than other forms of survey. Cameras have to be placed in the air for images to be collected. The there are special ways finding out all about the dimensions of the place with amazing clarity. Aerial surveying is used to provide information about archaeology, land survey, mining, monitoring the populations of wildlife as well as assessing vegetation cover. Such information is used to highlight ways through the ecosystem of a locality mush as a result of the project.
Aerial surveying has proven to be of use in many countries during construction of important infrastructural facilities. The most noticeable among them is the Sea-to-sky-Highway that was recently mapped in the British Columbia. This was a very coordinated plan that was aimed at making the area accessible in an environmentally friendly manner. Considerations were therefore made to satisfy recreational and cultural needs of the neighboring community. The bear habitat would be interfered with no more and industrial use of the highway would be permitted after certain policies have been adhered to. Means of transport that are not motorized were not interfered with. Motorcycles, bicycles and carts might be allowed to use the highway without meeting any standards.
Companies that conduct aerial surveying have to work with many other companies involved in the project. The Sea-To-Sky highway was recently successfully mapped using aerial surveying. A custom aerial photo had to be prepared as a guide to other more complicated surveys that would take a longer time to complete. A colored orthophoto was also developed and became very useful for surveying the length of road that extends from Horseshoe Bay to Whistler. This work was commissioned and supervised by the Ministry of Transportation of British of Columbia.
The highway passes through Vancouver, the rain forest of Horseshoe Bay, and through Squamish and Garibaldi area. Two historic paths can now be used as one arrives at Pemberton Trail. The decision to map the Sea-to-Air Highway was a timely one. The Great eastern Railway has always been over-burdened by many accessibility problems. Skiers who wanted to reach the London Mountain encountered many problems and this is what made the provincial government to open up a new road that would reach out to the population at Horseshoe bay.
The Sea-to-sky corridor therefore made the best use of aerial surveying mechanisms that were used to accessibility of these rural areas. No wonder the backcountry section of BC is now proud of hosting more and more visitors. As the future of aerial surveying goes on to be brighter and brighter, other projects similar to the Sea-To-Sky highway will take shape.
