The control difficulty index (CDI) has been developed to provide a spatial assessment of the estimated difficulty of enacting an African Swine Fever (ASF) suppression program given an outbreak for any... more region across Australia. This layer is estimated at a spatial grain of 30-arcseconds (approx. 1 km2). The index provides a representation of the estimated difficulty for human enacted control actions and does not include information on the predicted densities of feral pigs or their ecology/behaviours given different habitat types. As such, the index does not integrate difficulties of control that could arise from the ability to find and kill pigs or the efficacy of any particular control strategy (e.g. baiting vs shooting) given differences in terrain. Using satellite remote sensing data products and distance measures, this index combines several factors that will influence the difficulty of undertaking control across Australia by capturing the difficulty in mobilising resources into a region, the difficulty in undertaking ground control once arrived in the infected zone and the ability to undertake aerial control and/or carcass removal. To achieve this the index integrates measure that include, terrain ruggedness, road and track networks, land use type and canopy cover and remoteness from population centres. This Index was developed to support national planning for African Swine Fever and was developed rapidly at a coarse resolution. The index can be modified for local conditions and the base code is available on request. 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

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
