1/17/2024 0 Comments Convert im object into raster in rSee ncdfgeom for more about this NetCDF-based format for geometry and timeseries.įor the xts methods, if dimensions are provided, time has to be the first dimension.In my last blog post, I talked about how to identify and test for inhomogeneity of a point process, and I stated that the best way to characterize an inhomogeneous point process is to fit a good parametric model. Logical should a stars_proxy object be created? (requires gdal_create binary when sf = 1.0-7).įor the ncdfgeom method: objects are point-timeseries with optional line or polygon geometry for each timeseries specified with the sf_geometry parameter. Integer number of cells in z direction if missing no z-dimension is created. Logical should all cells entirely fall inside the bbox, potentially not covering it completely ( TRUE), or allways cover the bbox ( FALSE), or find a good approximation ( NA, default)? Logical should cell coordinates have pretty values? The (approximate) target number of grid cells Value(s) to populate the raster values with Length 2 numeric vector with extent (min, max) in y direction Length 2 numeric vector with extent (min, max) in x direction Numeric or object of class units cell size in y direction see details Numeric or object of class units cell size in x direction see details Integer number of cells in y direction see details Integer number of cells in x direction see details Object of class crs with the coordinate reference system of the values in curvilinear see details x the names of this vector should correspond to raster dimensions the matrices are associated with see Details. Only for creating curvilinear grids: named length 2 list holding longitude and latitude matrices or stars arrays, or the names of the corresponding attributes in. x is of class nc_proxy, argumentsĬharacter the names of the dimensions that denote raster dimensions x is of class bbox, arguments passed on to , att = 1, ignore_file = FALSE)Īs_attributes = all(terra::is.factor(.x)) , curvilinear = NULL, crs = st_crs("OGC:CRS84")) write_stars: write stars object to gdal dataset (typically: to file)Ĭonvert objects into a stars object Description.st_xy2sfc: replace x y raster dimensions with simple feature geometry.st_warp: Warp (resample) grids in stars objects to a new grid.st_transform: transform geometries in stars objects to a new coordinate.st_tile: Specify parameters to load raster in blocks.st_sfc2xy: replace POINT simple feature geometry list with an x y raster.st_set_bbox: set bounding box parameters of regular grid.st_rgb: reduce dimension to rgb (alpha) hex values.st_res: obtain (spatial) resolution of a stars object.st_raster_type: get the raster type (if any) of a stars object.st_rasterize: rasterize simple feature geometries.st_mosaic: build mosaic (composite) of several spatially disjoint stars.st_join.stars: Spatially join a stars and an 'sf' object.st_intersects.stars: spatial intersect predicate for stars and sfc object.st_extract: Extract cell values at point locations.st_downsample: downsample stars or stars_proxy objects.st_dim_to_attr: create an array with dimension values.st_dimensions: get dimensions from stars object.st_coordinates: retrieve coordinates for raster or vector cube cells.st_contour: Compute or plot contour lines or sets.st_cells: return the cell index corresponding to the location of a set.st_as_stars: convert objects into a stars object.st_as_sf: Convert stars object into an sf object.stars_sentinel2: Sentinel-2 sample tile.st_apply: st_apply apply a function to one or more array dimensions.redimension: redimension array, or collapse attributes into a new.read_stars: read raster/array dataset from file or connection.read_ncdf: Read NetCDF into stars object.print_stars: print stars or dimensions object.predict.stars: Predict values, given a model object, for a stars or.plot: plot stars object, with subplots for each level of first.ops_stars: S3 Ops Group Generic Functions for stars objects.mdim: Read or write data using GDAL's multidimensional array API.make_intervals: create an intervals object.L7_ETMs: Landsat-7 bands for a selected region around Olinda, BR.in-methods: evaluate whether cube values are in a given set.geom_stars: ggplot geom for stars objects.cut_stars: cut methods for stars objects.c.stars: combine multiple stars objects, or combine multiple.contour.stars: plot contours of a stars object.coerce-methods: Coerce stars object into a Raster raster or brick.bcsd_obs: Monthly Gridded Meteorological Observations.aggregate.stars: spatially or temporally aggregate stars object.
