Kakadu LIDAR Project 2011 0.5m Contours maps
收藏资源简介：
0.5m Contours maps as shape files 4903 tiled files (1km x1km) with DBF, PRJ and SHX support files\n\n\nLineage: Fugro Spatial Solutions (FSS) were awarded a contract by Geoscience Australia to carry out an Aerial LiDAR Survey over the Kakadu National Park. The data will be used to examine the potential impacts of climate change and sea level rise on the West Alligator, South Alligator, East Alligator River systems and other minor areas.\nThe project area was flight planned using parameters as specified. A FSS aircraft and aircrew were mobilised to site and the project area was captured using a Leica ALS60 system positioned using a DGPS base-station at Darwin airport. The Darwin base-station was positioned by DGPS observations from local control stations. A ground control survey was carried out by FSS surveyors to determine ground positions and heights for control and check points throughout the area. All data was returned to FSS office in Perth and processed. The deliverable datasets were generated and supplied to Geoscience Australia with this metadata information.\n\nNEDF Metadata\n Acquisition Start Date: Saturday, 22 October 2011\n Acquisition End Date: Wednesday, 16 November 2011\n Sensor: LiDAR\n Device Name: Leica ALS60 (S/N: 6145)\n Flying Height (AGL): 1409\n INS/IMU Used: uIRS-56024477\n Number of Runs: 468\n Number of Cross Runs: 28\n Swath Width: 997\n Flight Direction: Non-Cardinal\n Swath (side) Overlap: 20\n Horizontal Datum: GDA94\n Vertical Datum: AHD71\n Map Projection: MGA53\n Description of Aerotriangulation Process Used: Not Applicable\n Description of Rectification Process Used: Not Applicable\n Spatial Accuracy Horizontal: 0.8\n Spatial Accuracy Vertical: 0.3\n Average Point Spacing (per/sqm): 2\n Laser Return Types: 4 pulses (1st 2nd 3rd 4th and intensity)\n Data Thinning: None\n Laser Footprint Size: 0.32\n Calibration certification (Manufacturer/Cert.
