With GIS, you can analyse topographic, environmental, demographic and land use data to help you with your business decisions and project management.eed and pest management. Invasive weeds and pests can lead to massive economic costs. GIS is used to determine the areas infested by mapping in the field (recording perimeters of infested areas or recording individual points/sightings) or using satellite imagery/remote sensing.
Definition of lidar. : a device that is similar in operation to radar but emits pulsed laser light instead of microwaves.
On a functional level, LiDAR is typically defined as the integration of three technologies into a single system capable of acquiring data to produce accurate digital elevation models (DEMs). These technologies are lasers, the Global Positioning System (GPS), and inertial navigation systems (INS).his seminar paper on LiDAR mapping provides an introduction to a maturing technology used to acquire land based Digital elevation Models (DEM), and an existing mature technology used to acquire marine (undersea) DEMs. This seminar also goes through the use of LIDAR in space programs.
