Handbook

Sources of image data for provision of spatial information; digital aerial and close range frame cameras, pushbroom aerial and satellite scanner systems; commercial imaging systems for built environments; airborne laser scanners (LiDAR). Geometry of frame and pushbroom scanner data systems; direct georeferencing of aerial and satellite systems; processing of multiple frame image data and pushbroom imagery spatial information extraction; block adjustment; accuracies of spatial data extracted from aerial images; ground control requirements: image processing for feature extraction, image matching, geometric correction of digital images, digital photogrammetric workstations; development of systems for sem-automatic and automatic extraction of feature extraction. Applications of digitial image data for mapping and close range metrology. Characteristics of LiDAR data, filtering, extraction of DEMs and other features; software for display and presentation of LiDAR data.
