Description

Considered flight plan was created to establish maximum imagery coverage and overlap of ground and building features, captured during consistent cloud cover to achieve optimum appearance. Aerial imagery was captured by helicopter at flying height of above 1000ft, capturing image frames at 2-3cm GSD. The photomesh product was processed in Bentley Context Capture and tied to field survey to achieve a target absolute accuracy of 5cm. The photomesh was then edited to remove anomalies and improve surface definition. Some anomalies within the dataset may still exist. A point cloud has also been outputted from the Photo Mesh generation process in LAS 1.4 format with RGB colour values from the imagery on each cloud data point. Dataset formats: - Collada 3D mesh tiles in DAE format. Please refer to the associated metadata.xml and tile_index.kml folder for global offsets and tile extents respectively. - ESRI I3S 3D Model in ESRI I3S SLPK unique mesh Format. - Cesium 3Dtiles 3D Model in Cesium 3Dtiles unique mesh. - True Ortho 2.5cm resolution ECW mosaic and tiff tiles. - Skyline TerraExplorer Kit Interactive 3D model kit. 5m DTM and 50cm Imagery provided as background data. - DSM 10cm digital surface model. - Point Cloud 10cm las.
