Description

RPS: LiDAR in this AOI was captured by RPS. The IMU and post processed airborne GPS logs were used to generate the LiDAR point cloud from the waveform instrument data. Raw LiDAR swaths were levelled to establish internal consistency, merged and 1km x 1km tiles in LAS v1.2 format were created. An automatic classification algorithm was applied in TerraScan software to produce an initial classification of ground (2) and unclassified (1). High and low noise points were automatically classified and allocated to class 7. On completion of the ground classification automatic algorithms were used to classify unclassified points to low vegetation (3), medium vegetation (4), high vegetation (5) and buildings (6). Review of the classification was completed on data present within the AOI only. The classification accuracy was not measured empirically. Manual editing of ground points were completed in areas where log piles were identified ¿ these log pile points were placed into 'unclassified' class 0. Concurrent photography was captured along with LiDAR and was supplied as a bonus product (ECW only, no tiles). No further documention is available for this ECW mosaic.
