XArray Methods

DEM Functions

load_dem(dem_file[, input_var_name, ...])	Load DEM from a raster file and prepare it for use with gsolve.
prepare_dem(dem[, input_var_name, ...])	Prepare a DataArray or DataSet for use with gsolve terrain correction methods.
check_dem(dem[, show])	Check dem has increasing and evenly spaced coordinates.
create_empty_dataarray([var_name, x_dim, y_dim])	Create an empty DataArray with specified dimensions.

Xarray Accessor Class and Methods

TCorrMethods(xarray_dataarray)	A class to providing accessor methods for xarray.DataArray objects.
TCorrMethods.xc	X coordinates as a numpy array.
TCorrMethods.yc	Y coordinates as a numpy array.
TCorrMethods.xdim	x dimension name.
TCorrMethods.ydim	y dimension name.
TCorrMethods.dx	Node separation in x direction.
TCorrMethods.dy	Node separation in y direction.
TCorrMethods.bounds	Return array extent as an ndarray of form (xmin, ymin, xmax, ymax).
TCorrMethods.cell_edges()	Return coordinates of cell edges.
TCorrMethods.coords_to_indices(point)	Convert cartesian coordinates (x, y) to array indices (i, j).
TCorrMethods.is_compatible(other)	Test that caller and other have same dimensions and size.
TCorrMethods.clip_to_arr(other[, clip_other])	Clip calling DataArray to the dimensions of other, or vice versa.
TCorrMethods.clip_to_points(points[, ...])	Return a copy of this array clipped to the extent of points + max_dist.
TCorrMethods.get_land_sea_mask([...])	Generate a mask array where "land" areas are True and "sea" areas are False.
TCorrMethods.generate_distance_mask([point, ...])	Generate a boolean distance mask from a specified point.
TCorrMethods.apply_mask(mask[, fill_value])	Mask calling DataArray and set masked elements to fill_value.
TCorrMethods.generate_bathymetry_density([...])	Generate a bathymetry density grid from a boolean mask grid or DEM.
TCorrMethods.generate_topo_density([...])	Generate a terrain density grid.
TCorrMethods.get_bathymetry_elevation([...])	Return an array with all elevations > sea level set to sea level.
TCorrMethods.get_topography_elevation([...])	Return an array with all elevations < sea level set to sea level.
