15 Applications and Uses of Drones in GIS
GIS (Geographic Information System) has revolutionized the world. It has left an indelible mark in certain disciplines or field of study such as geography, geology, astrology, oceanography, cartography and so on has transformed. GIS did not just change the face of this disciplines, it elevated to them another pedestal and give them a new dimension. For an analyst, it became a vital tool and framework of analysis.
There are a plethora of software, tool and gadget out there that can better or improve GIS. One of them is Drones. A drone is an unmanned aerial vehicle (UAV) aircraft without a human pilot aboard. The flight of UAVs may operate with various degrees of autonomy: either under remote control by a human operator or fully or intermittently autonomously, by onboard. In other words, a drone is not always piloted by a pilot. The question lingering is: How do drones improve GIS?
The following are 15 application and uses of drones in GIS:
15. LiDAR Data production
LiDAR provides a riches of information for many applications and offers several advantages over old methods for aerial mapping. All these applications can take advantage of combining LiDAR and GIS to conduct analysis and visualize, manage, and disseminate LiDAR data.
The combination of drones and LiDAR is a relatively new land surveying technique, which is based on high precision laser scanners, the global positioning system (GPS) and Inertial Navigation Systems (INS). Combined, they have powerful built-in signal processing, large field of view, and multi-segment measurements which generate critical distance data and efficient obstacle detection which enable safe navigation when performing structural inspections using altimeter technology.
