Advances in Mapping and Aerial Surveying Make Work Easier

Land surveying is the scientific method used to precisely determine the 3D (three-dimensional) or the terrestrial points, angles and distances between them. These points are used to detect and map the boundaries of land for government purposes or ownership. Surveyors typically utilize engineering, mathematics, law, physics and geometry for mapping and land surveys. If you are looking for lidar liability insurance then check

Mapping and aerial survey is needed in land surveying. While most of the earth's surface was photographed at a certain height to create the map, many techniques require a better view of the ground at a larger scale, together with more accurate data points. It is created from satellite imagery, and helicopters or aircraft used in taking photographs of land.

Since the development of this technology is becoming increasingly popular, especially after the launch of Sputnik, which marked the start of the period of satellite imagery.

Photogrammetry is a method of remote sensing of the earliest used to create the map, and is still used. It determines the measurement through photography in which data is collected every second of air flights.

On the other hand, using 3D laser technology subtle, and setting foot on the ground is not required. It is beneficial for the surveyor in charge of surveying the steep slopes and dangerous terrain. Mapping land with limited access is made easy with aerial mapping. This includes the creation of 3D maps through accurate measurement of the location and elevation, as opposed to aerial photographs, which failed to produce data accurate or detailed.

LIDAR (Laser Imaging Detection and Ranging) technology using laser beams to create 3D land picture or model. When used in conjunction with GPS (Global Positioning System) equipment, LIDAR elevation collect location data and then transformed into a geographic map. Data collected is used in applications such as topographic maps.
