This satellite data set compromises of 6057 daily MODIS-Aqua (NASA) image acquisitions covering the Van Diemen Gulf region, NT. MODIS Level 0 data (e.g. raw counts) were processed using NASA’s SeaWiFS... more Data Analysis System (SeaDAS) software package version 7.0. Most up-to-date calibration tables and other auxiliary inputs (e.g. meteorological information) where incorporated into the processing with SeaDAS to account for sensor degradation and to compute calibrated and geo-located radiances at Top-of-Atmosphere (TOA) as Level 2 outputs. These were subsequently re-projected from satellite swath geometry to an equal-rectangular grid (445 x 550 pixels) covering 130.5° E and 133° E in longitude and 11° S and 13° S in latitude. The re-projected data were further processed using CSIRO’s regionally tuned ocean colour algorithms based on Artificial Neural Network (ANN) atmospheric correction and adaptive Linear Matrix Inversion (aLMI) in-water retrieval. less

Digital Surface Model (DSM) 1metre ESRI Grid Float format as 4942 tiles. There is no common usage of the terms digital elevation model (DEM), digital terrain model (DTM) and digital surface model (D... moreSM) in scientific literature. In most cases the term digital surface model represents the earth's surface and includes all objects on it. In contrast to a DSM, the digital terrain model (DTM) represents the bare ground surface without any objects like plants and buildings. Digital Elevation Model (DEM) and Digital Terrain Model (DTM) appear to be used interchangeably. less

LiDAR_Point_Clouds, Classified. AHD have been preocessed to conform to the Australian Height Datum and converted from files collected as swaths in to tiles of data. The file formats is LAS. LAS is ... morean industry format created and maintained by the American Society for Photogrammetry and Remote Sensing (ASPRS). LAS is a published standard file format for the interchange of lidar data. It maintains specific information related to lidar data. It is a way for vendors and clients to interchange data and maintain all information specific to that data. Each LAS file contains metadata of the lidar survey in a header block followed by individual records for each laser pulse recorded. The header portion of each LAS file holds attribute information on the lidar survey itself: data extents, flight date, flight time, number of point records, number of points by return, any applied data offset, and any applied scale factor. The following lidar point attributes are maintained for each laser pulse of a LAS file: x,y,z location information, GPS time stamp, intensity, return number, number of returns, point classification values, scan angle, additional RGB values, scan direction, edge of flight line, user data, point source ID and waveform information. Each and every lidar point in a LAS file can have a classification code set for it. Classifying lidar data allows you to organize mass points into specific data classes while still maintaining them as a whole data collection in LAS files. Typically, these classification codes represent the type of object that has reflected the laser pulse. Point classification is usually completed by data vendors using semi-automated techniques on the point cloud to assign the feature type associated with each point. Lidar points can be classified into a number of categories including bare earth or ground, top of canopy, and water. The different classes are defined using numeric integer codes in the LAS files. The following table contains the LAS classification codes as defined in the LAS 1.1 standard: Class code Classification type 0 Never classified 1 Unassigned 2 Ground 3 Low vegetation 4 Medium vegetation 5 High vegetation 6 Building 7 Noise 8 Model key 9 Water less
