Aerial survey is a method of collecting geomatics or other imagery data using airplanes, helicopters, UAVs, balloons, or other aerial methods. Typical data collected includes aerial photography , Lidar , remote sensing (using various visible and invisible bands of the electromagnetic spectrum , such as infrared , gamma , or ultraviolet ) and ...
The principle is similar to a magnetic survey carried out with a hand-held magnetometer, but allows much larger areas of the Earth's surface to be covered quickly for regional reconnaissance. The aircraft typically flies in a grid-like pattern with height and line spacing determining the resolution of the data (and cost of the survey per unit ...
Geophysical surveys may use a great variety of sensing instruments, and data may be collected from above or below the Earth's surface or from aerial, orbital, or marine platforms. Geophysical surveys have many applications in geology, archaeology, mineral and energy exploration, oceanography, and engineering. Geophysical surveys are used in ...
Data from Conservation International on areas of the world with especially high endemism and high numbers of threatened species. Pilot Analysis of Global Ecosystems: Forest Ecosystems: Data from the World Resources Institute includes: percentage tree-cover, population density and tree cover, share of wood in fuel consumption, etc.

Aerial photograph interpretation is a method of extrapolating geological details of the ground surface from aerial images. [1] It allows geologists to analyze the distinguishing geological features and structures , plant cover , past history of the site, soil properties, and topography of the study area.
An aerial photograph marks different data and information about the covered area and the airplane's position and condition. [2] These details are measured and noted by the data panel which includes different devices and instruments for the specific measurements. [2] Figure 8 shows the general format of a vertical aerial photograph.
Aerial archaeological survey combines data collection and data analysis. [3] The umbrella term "aerial images'" includes traditional aerial photographs, satellite images, multispectral data (which captures image data within specific wavelength ranges across the electromagnetic spectrum) [ 4 ] and hyperspectral data (similar to multi-spectral ...
