Arial image showing fire damage. Pointcloud derived from SfM Photogrammetry. TYPE: Laser scanning. KEYWORDS: Combining terrestrial laser scan and aerial SfM point cloud data. INTRODUCTION he proliferation of terrestrial laser scanners in the as-built survey industry has allowed survey companies to generate vast amounts of accurate, reliable point cloud measurement data quickly and safely, allowing the production of high quality 2D measured survey drawings. However, there are sometimes areas where it may be difficult or impossible for terrestrial based laser scanning to acquire, such as those that may have restricted or unsafe access. In an effort to overcome these difficulties and ultimately increase the coverage of available data, Greenhatch Group took the decision to employ th
