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.
In both coherent and incoherent lidar, there are two types of pulse models: micropulse lidar systems and high energy systems. Micropulse systems have developed as a result of the ever increasing amount of computer power available combined with advances in laser technology.his lidar may be used to scan buildings, rock formations, etc., to produce a 3D model. The lidar can aim its laser beam in a wide range: its head rotates horizontally; a mirror tilts vertically.
