Synergistic Use of Lidar and Color Aerial Photography for Mapping Urban Parcel Imperviousness
The imperviousness of land parcels was mapped and evaluated using high spatial resolution digitized color orthophotography and surface-cover height extracted from multiple-return lidar data. Maximum-likelihood classification, spectral clustering, and expert system approaches were used to extract the impervious information from the datasets. Classified pixels (or segments) were aggregated to par...
متن کاملSynergistic Use of LiDAR and APEX Hyperspectral Data for High-Resolution Urban Land Cover Mapping
Land cover mapping of the urban environment by means of remote sensing remains a distinct challenge due to the strong spectral heterogeneity and geometric complexity of urban scenes. Airborne imaging spectroscopy and laser altimetry have each made remarkable contributions to urban mapping but synergistic use of these relatively recent data sources in an urban context is still largely underexplo...

متن کاملUse of airborne LiDAR and aerial photography in the estimation of individual tree heights in forestry
This document describes the use of aerial photography and airborne LiDAR to estimate individual tree heights in forest stands. The advantages and disadvantages in the use of LiDAR systems are revised and a data fusion analysis with digital aerial photography is proposed. The work shows an example of these techniques in a forested area in Scotland. An algorithm has been devised to extract a high...
متن کاملMapping parcel-level urban areas for a large geographical area
As a vital indicator for measuring urban development, urban areas are expected to be identified explicitly and conveniently with widely available dataset thereby benefiting the planning decisions and relevant urban studies. Existing approaches to identify urban areas normally based on midresolution sensing dataset, socioeconomic information (e.g. population density) generally associate with low...
