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.
- transmits microwaves in pulses - determines distance to objects and their angular position (from side) LiDAR - transmits optical laser light in pulses - determines distance to objects History of LiDAR - laser ranging developed in the 1960s - LiDAR terrain mapping began in 1970s - initial systems were âsingle beamâ, profiling devices - early use for terrain mapping limited by lack of accurate geo-referencing - early systems used for bathymetry
