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.
LIDAR. LIDAR uses ultraviolet, visible, or near infrared light to image objects and can be used with a wide range of targets, including non-metallic objects, rocks, rain, chemical compounds, aerosols, clouds and even single molecules.A narrow laser beam can be used to map physical features with very high resolution.avelengths in a range from about 10 micrometers to the UV (ca. 250 nm) are used to suit the target. Typically light is reflected via backscattering. Different types of scattering are used for different LIDAR applications; most common are Rayleigh scattering, Mie scattering and Raman scattering, as well as fluorescence.
