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.
45 Introduction Light Detection and Ranging (LiDAR) is a remote sensing tool that can potentially be used to conduct timber inventories. LiDAR has been used for the quantification of biomass, tree and stand height, and basal area estimation (Nelson et al.he LiDAR inventory costs included the cost of obtaining the LiDAR data, the ground plots for determining the height volume relationship, and LiDAR data processing. If LiDAR data are already available, the cost of extracting the plots and processing the data for timber inventory is very low.
