What Aerial Mapping Is
The technical way to describe aerial mapping is that it is a form of mapping that uses Aero Triangulated aerial imagery to make planimetric maps that contain features and contours from the imagery. Aero Triangulation is what brings accuracy to this type of mapping because it measures multiple horizontal and vertical field points within one image and uses a specific formula to generate the needed information.
This method of aerial mapping is not simply aerial photography like many may think. It certainly involves the capturing of images, but these images take into account the different terrain features and formations so that the maps made from these images can have more than just a flat image to work with. The images produced from aerial mappings are very detailed terrain guides that help with many types of projects and planning.
How 3D Scanning & Aerial Mapping Is Done
Often, with the new and constantly improving drone technology, drones are used to capture 3D scanning images or are made with the right software to capture the data needed for aerial mapping. These tend to be quite accurate and generally less expensive than upkeep on a plane and saving time since less manpower is needed. These are really only used for short range mapping projects, though.
Traditionally, and still currently, much of the aerial mapping is done by humans in a plane or helicopter outfitted with the right tools to capture the images and information they need. This method of aerial mapping has been around for quite a while, and the equipment involved must be able to stabilize the cameras and point the camera at the correct angle while taking a picture. When the wrong angles are used, the pictures do not line up, and the angles are distorted and unreadable. It is not an easy task, but it is an important one.
Why Aerial Mapping Is Important and Useful
Aerial mapping can be a great way to avoid future issues related to geographical layout of an area. Paying attention to an aerial map and knowing how to analyze the information it gives can potentially avoid the risk of natural disasters and hazards.
Land management and planning can be done much more efficiently and effectively when aerial maps are used to assess a large area of land. The layout and topography of the map will help engineers and scientists plan anything from drainage systems and construction planning to archaeology and excavation. Wildlife monitoring and reconnaissance are also common reasons why aerial mapping is needed.
Cartographers need the detailed images and measurements from aerial mapping to make many different types of maps. A flat image is of little use to a cartographer making a realistic and technical map.
Who Does Aerial Mapping
Those who specialize in aerial mapping are usually called aerial surveyors. These people use a multitude of different vehicles and gadgets to get the job done right. The vehicles they use include aero planes, helicopters, UAVs, and balloons. The gadgets and technology they need to be able to use include: Many types of cameras, LiDAR, aeromagnetic surveys, remote sensing, etc.
Aerial surveyors or cartographers are usually learned in the fields of geology, cartography, photography, geometry, physics and mathematics (to name a few). They often use the term aero photogrammetry to describe what they do – it basically means that a camera is placed in the air.
