Improvement of Lidar Data Accuracy Using Lidar-Specific Ground Targets
With recent advances of lidar technology, the accuracy potential of lidar data has significantly improved. State-ofthe-art lidar systems can achieve 2 to 3 cm ranging accuracy under ideal conditions, which is the accuracy level required by engineering scale mapping. However, this is also the accuracy range that cannot be realized by routine navigation-based direct sensor platform orientation. F...
متن کاملLIDAR As An Effective Method For Coastal Habitat Mapping
Overview: Mapping along the coastlines of the United States has historically been an epic battle for the most accurate representation of the shoreline. This effort has been felt by all agencies of the government and private sector as inhabitation near our oceans has skyrocketed in the last half century. These agencies look for the most accurate data to convey to their constituents, customers an...
متن کاملFlood Risk Mapping Using LiDAR for Annapolis Royal, Nova Scotia, Canada
A significant portion of the Canadian Maritime coastline has been surveyed with airborne Light Detection and Ranging (LiDAR). The purpose of these surveys has been to map the risk of flooding from storm surges and projected long-term sea-level rise from climate change and to include projects in all three Maritime Provinces: Prince Edward Island, New Brunswick, and Nova Scotia. LiDAR provides th...
متن کاملCombining Lidar Elevation Data and IKONOS Multispectral Imagery for Coastal Classification Mapping
This article studies the effect of airborne lidar (surface) elevation data on the classification of multispectral IKONOS images over a coastal area. The lidar data and IKONOS images are treated as independent multiple bands to conduct the classification. To do so, the lidar elevation data is first resampled to the same ground spacing interval and stretched to the same radiometric range as the I...
متن کاملA New Approach for Assessing Lidar Data Accuracy for Corridor Mapping Applications
There is a growing demand for high-accuracy elevation data collected by airborne or terrestrial mobile lidar systems in utility corridor surveys. Large-scale projects demand more stringent accuracy of lidar data under strongly variable survey conditions challenging lidar signal detection capability with extremely wide signal dynamic range. While accuracy specifications are provided by the lidar...
