Terms Related to Aerial Surveying
Aerial surveying is mapping work done from studying an aerial photograph or image. This type of surveying is often used for large construction projects, archeology projects, mining projects, wildlife projects and even reconnaissance work. The point of providing an aerial survey is to give an overall view of a large area that can only be completely seen by air. Historically this work was done using hot air balloons, but today is accomplished using manned and unmanned aircraft and even satellite imagery. Below are some common terms for aerial surveying.
Topography – A special type of map that shows elevation differences. A map is drawn using a set of lines based on a set of elevation intervals. Topographic maps are usually designed from aerial views, which can give an overall view of the landscape. Changes in elevation are also sometimes further enhanced by coloring.
Geospatial Analysis – A type of geographic analysis that uses mathematics equations. For example, a satellite photo taken from the air includes no markers, such as distances. Geospatial analysis takes into account the height of the camera when creating an equation to find out the area of the land in the photo.
UAV – Short for Unmanned Aerial Vehicle. Once strictly the domain of the army, UAVs gained popularity with reconnaissance work. Some UAVs are used for commercial purposes, such as taking aerial photographs for aerial surveys.
Geological Map – A map that shows primarily geological features, such as mountains, lakes and important natural landmarks. These are usually designed from aerial surveys, which can provide accurate pictures of the overall area.
Aerial surveyors are useful because they can take photographic images of land and real estate from satellites that give you a better perspective than you get on the ground. Surveying the land in this way makes it easier to create accurate maps that can be used to determine property lines, what areas are suitable for building construction, and designing transportation and communications systems. If you need aerial surveyor services, then you will need to contact a company that can give you the services that you need at an affordable price. There are several companies listed in your online directory that have topographers that can help you retrieve satellite photographs that will make repairing, refurbishing, and maintenance easier for communications lines and transport systems. They can also give you cadastral services that will help you make a map with accurate property lines. When you contact the companies, you should ask them how long they have been in the aerial surveying business. You should choose a company with several years of experience because they should know more about using satellite images and photographs. They should also have experienced professionals who can give you customized services with accurate results so that you do not have to worry about getting another survey of the land. Of course, you should also consider the differences in the companies' prices so that you can stick to a reasonable budget. Ask them to write price quotes for you that include all of their fees to help you make your decision.
