Topographic survey using drones: Drones are unmanned aerial vehicles that can be flown over any area and gather topographical information by utilizing cameras or laser scanners.
A topographic survey is a map or drawing of the topography of an area. It provides slope, elevation, and other important data about all-natural features. It can be used to identify potential construction sites and environmental hazards. Ground crews have traditionally done this type of topographical study with equipment such as tape measures, levels, transits, and electronic distance measurement devices (EDMs). With the recent rise in the popularity of drones among topographers, there have been some significant changes to how this work is performed.
1) Drones can capture high-resolution imagery at a much lower cost than traditional methods for topographic surveys.
2) They can be deployed in areas where it would otherwise be impossible or dangerous to send humans because they are not affected by weather conditions like strong winds or cold temperatures.
3) Aerial photography from drones can also provide information about buildings, trees, vegetation cover on hillsides – all important considerations when mapping an area.
Please note topographic surveys are different than topographical maps, which show elevation changes in the land. In contrast, a topographic survey is used to map out a specific property or region.
