![]() If the k flag is set, extracted files from compressed archives are also kept within the However, unzipped files and imported rasters before patching are removed. These files can be reused in case a different, but overlapping, computational Is displayed without downloading the data.īy default, downloaded files are kept in a user cache directory according to If the i flag is set, only information about data meeting the input parameters If multiple tiles from different yearsĪre available, use title_filter to filter by their titles (e.g. In some cases, lidar point clouds do not have SRS information, use input_srs Will be imported as points using v.in.pdalĪnd then patched and interpolated with v.surf.rst. Spatially overlapping datasets from different years. ![]() Lidar data is available only for part of the US but there can be multiple ![]() NED data are available at resolutions of 1 arc-second (about 30 meters),ġ/3 arc-second (about 10 meters), and in limited areas at 1/9 arc-second (about 3 meters). National Land Cover Dataset (NLCD) is no longer available through the API. R.in.usgs supports the following datasets: The National Map Access API, downloaded to a local cache directory, The current GRASS computational region and coordinate reference system.Īssociated parameters are automatically passed to cache)ĭESCRIPTION r.in.usgs downloads and patches selected USGS datasets (NED, NAIP, lidar) to resampling_method= string Resampling method to use Options: default, nearest, bilinear, bicubic, lanczos, bilinear_f, bicubic_f, lanczos_f Default: default default: default method based on product nearest: nearest neighbor bilinear: bilinear interpolation bicubic: bicubic interpolation lanczos: lanczos filter bilinear_f: bilinear interpolation with fallback bicubic_f: bicubic interpolation with fallback lanczos_f: lanczos filter with fallback memory= integer Maximum memory to be used (in MB) Cache size for raster rows during import and reprojection Default: 300 nprocs= integer Number of processes which will be used for parallel import and reprojection Default: 1 output_directory= name Cache directory for download and processing Defaults to system user cache directory (e.g. use "Phase4") To avoid combining lidar from multiple years, use first -i flag and filter by tile title.
