Airborne mapping using LIDAR
Mapping is a central and common task in robotics research. Building an accurate map without human assistance provides several applications such as space missions, search and rescue, surveillance and can be used in dangerous areas. One application for robotic mapping is to measure changes in terrain volume. In Sweden there are over a hundred landfills that are regulated by laws that says that th...
متن کاملForest Modeling using Airborne Lidar
Building up forest inventories for performing forest management is currently done manually through field cruises and interpretation of the aerial imagery, which is a labor-intensive task. Airborne lidar technology is capable of building a point cloud off the top surface of the ground objects. Modeling urban areas from the lidar has been successfully accomplished. However, for forest modeling, t...
متن کاملDetecting tropical forest biomass dynamics from repeated airborne Lidar measurements
ha or more. Our results indicate that the 50-ha BCI plot lost a significant amount of 20 biomass (−0.8±2.2Mgha−1 yr−1) over the past decade (2000–2010). Over the entire island and during the same period, mean AGB change is −0.4±3.7Mgha−1 yr−1. Old growth forests lost biomass (−0.7±3.5Mgha−1 yr−1), whereas the secondary forests gained biomass (+0.4±3.4Mgha−1 yr−1). Our analysis demonstrates that...
متن کاملMapping Canopy Height and Growing Stock Volume Using Airborne Lidar, ALOS PALSAR and Landsat ETM+
We have investigated for forest plantations in Chile the stand-level retrieval of canopy height (CH) and growing stock volume (GSV) using Airborne Laser Scanner (ALS), ALOS PALSAR and Landsat. In a two-stage up-scaling approach, ensemble regression tree models (randomForest) were used to relate a suite of ALS canopy structure indices to stand-level in situ measurements of CH and GSV for 319 sta...
متن کاملAirborne and Spaceborne Lidar
The evolution of lidar, from those early ground-based measurements to our first long-duration spaceborne experiments, is schematically represented in Fig. 13.1. It depicts the first lidars in the 1960s as ground-based, followed by systems first flown in 1969 on small aircraft, and followed in the late 1970s by lidars flown on large aircraft capable of long-range measurements. Starting in 1979, ...
