Are you looking to find out more information on aerial mapping?

Aerial mapping involves photographing a piece of land from an aircraft. It usually involves two shots of an area, which are overlapping. The photographs are taken with the help of cameras mounted on the underside of the plane. These photographs are then seamed together to give an accurate picture of what a piece of land actually looks like from above.

Aerial mapping has now become an important aspect of land surveys. It’s necessary to have an aerial map of an area before construction begins on a particular project. Aerial mapping is necessary for the following

  • Architecture and land development
  • To carry out the environmental research on terrains and certain topographic areas.
  • In town development or city planning.
  • Sometimes aerial data comes in handy in the process of filming as well.

However necessary aerial mapping is, it does have its pros and cons. Read on to find out what are a few benefits and disadvantages of Aerial Mapping. Aerial mapping is the solution to quick high quality mapping information. Lester Franks are Aerial Mapping experts, contact them today to consult with a specialist.

The Advantages of Aerial Mapping

  • Since aerial shots can give an unobstructed view of an area, it can’t be equaled by any map.
  • Another great benefit of aerial mapping is that it can be obtained in the shortest possible time, often only hours after an aerial shot has been taken. This can help speed up a process for any engineering work to begin quickly.
  • It can help get accurate shots of places which can’t be accessed easily from the ground.
  • It can help get an idea about different military features which can’t be seen of an ordinary map.
  • Aerial mapping is especially handy in terms of military use. It’s a great way to get an idea regarding the things which happen on the rival’s area.
  • It provides an accurate record of day to day changes which happen in a particular area and which are not so easily available while looking at the map. Usually because the map may be old or obsolete.

The Cons of Aerial Mapping

  • Often aerial maps are not very accurate. This is especially true in cases the land is situated in a forest or a rocky terrain. The position of some ground features are easily obstructed by some other ground details.
  • You can only obtain an approximate value of an exact position of any ground feature.
  • In order to get detailed view additional equipment is required like a stereoscopic viewing instrument.
  • Unlike a map which has the necessary marginal data, an aerial photograph has none. This can make it difficult for engineers to get an exact idea about the dimensions of a particular area.
  • It even requires an eye for detail for reading it accurately. Unlike maps which have all the topographic features displayed clearly an aerial photograph might have some features obstructed.

Despite some of the disadvantages of aerial mapping, sophisticated equipment like digital data processors has made it easier to read aerial maps. When used in conjunction with GIS data these aerial maps tend to be more accurate than usual topographic maps. 3D laser scanning provides geographical and engineering information on your location. This company’s 3D laser scanning and metrology services are known as the best in Australia.
