Data Management Based on Geocoding Index and Adaptive Visualization for Airborne Lidar
نویسندگان
چکیده
With more surveying practice and deeper application, data post-process for airborne LiDAR system has been extracted lots of attention in data accuracy, post-process, fusion, modeling, automation and visualization. However, post-process and flexible visualization were found to be the bottle-neck which limits the LiDAR data usage for industrial applications. The cause of above bottle-neck problems is great capacity for LiDAR system. Thus in article a geocoding index based multivariate data management and adaptive visualization will be studied for based on the feature of airborne LiDAR’s data to improve automatization of postprocess and surveying efficiency. * Xiaodong Zhi.

متن کاملDetermination of Large-scale Digital Elevation Model in Wooded Area with Airborne Lidar Data by Applying Adaptive Quadtree-based Iterative Filtering Method
Generation of large-scale digital elevation (or terrain) models of wooded areas is fundamental to LIDAR data’s application in forest management to a large extent. In this paper, a new method is proposed and implemented, which is characterized by its combination of adaptive quadtree-based processing with common iterative interpolation and filtering methods. Digital elevation models (DEM) of wood...
متن کاملSpace-Filling Curve Based Point Clouds Index
Managing large volume points clouds data generated from laser scanner is a challenging problem in Geographic Information System (GIS) and spatial database. Based on analyzing the pros and cons of the existing management methods, this paper presents a method to manage lidar data in databases based on the Hilbert space-filling curve. Each lidar data point (X, Y, and Z) is encoded (indexed) by the...
