Find a point p_out that is width away from p and such that p_up --> p is right-perpendicular to p --> p_out. Parameters ---------- p_up :

Find a point that is perpendicular to the linestring p_up --> p --> p_dn. Projects by intersecting two lines, one parallel to p_up --> p and widt

Replace this node with a sequence of other nodes. This is equivalent to deleting this node from the child list, and then

Reverse the direction of a LineString. Parameters ---------- ls : shapely.geometry.LineString LineString to reverse.

Maps 2D cell ID and index in the vertical to a 3D cell ID. Parameters ---------- column : int 2D cell ID.

Construct boundary polygon and return a copy.

Establish a request for a dataset for the given geometry and time range. Parameters ---------- geometry : shapely.geometry.Po

Append a child (upstream) reach to this reach.

Merges this node with its parent. Parameters ---------- merge_reach : bool, optional Whether to merge the l

Given a list of linestrings whose terminal coordinate is the same, compute angles between each successive pair of strings.

Add BoundaryEntry object to the waterway

Compute line coefficients (Ax + By + C = 0) for a line defined by two points. Parameters ---------- p1 : np.ndarray First point c

Fetch the request and get the actual data.

Returns next available LS id.

Parse a variable name to extract base variable and layer. Parameters ---------- var_name : str Variable n

Forms a list of River trees from a list of reaches by looking for close endpoints of those reaches. Parameters ----------

Read the project setup.cfg file to determine Versioneer config.

Get the project root directory. We require that all commands are run from the project root, i.e. the directory that contains setup.py, setup.

Get the project version from whatever source is available. Returns dict with two keys: 'version' and 'full'.

Is the request ready for fetching?

Warp the coordinate system.

Add a child to this node. :child A Tree object

Generator for edges of a cell. Parameters ---------- conn : List[int] Cell connectivity (vertex indices).

If coordinates are changed, any computed, cached geometry must be recomputed. It is the USER's responsibility to call this function i

Hashes edges in a direction-independent way. Parameters ---------- i : int First vertex index. j

return node for a given index

Iterate over the polygons.

Removes this node and all below it, merging properties. This method removes the entire subtree rooted at this node, but first

Transform a 2D mesh. Parameters ---------- mat : np.ndarray, optional 3x3 transformation matrix. Default

Computes, based on coords, the centroid of a cell with ID c. Note this ALWAYS recomputes the value, not using the cache.

Generator for handles

Checks for monotonically decreasing elevation as we march downstream in this reach.

A generator for the nodes on the path to root, including this.

Maps 2D vertex ID and index in the vertical to a 3D vertex ID. Parameters ---------- vertex : int 2D vert

Helper function to make a straight reach along y=0 given elevs.

Moves the ith coordinate of self.linestring to a new location.

Return a + if we don't already have one, else return a .

Return a + if we don't already have one, else return a .
