Planview operations

The package makes available functions relating to planview operations on data.

The functions are defined in deltametrics.plan.

Hint

There is a complete Planform Subject Guide about the organization of this area of DeltaMetrics and examples for how to use and compute planform objects and metrics.

Planform types

Basic data Planform

Planform(*args[, z, t, idx])

Basic Planform object.

Specialty Planforms

OpeningAnglePlanform(*args, **kwargs)	Planform for handling the Shaw Opening Angle Method.
MorphologicalPlanform(*args, **kwargs)	Planform for handling the morphological method.

Functions

compute_land_area(land_mask)	Compute land (delta) area.
compute_shoreline_roughness(shore_mask, ...)	Compute shoreline roughness.
compute_shoreline_length(shore_mask[, ...])	Compute the length of a shoreline from a mask of the shoreline.
compute_shoreline_distance(shore_mask[, ...])	Compute mean and stddev distance from the delta apex to the shoreline.
compute_channel_width(channelmask[, ...])	Compute channel width from a mask and section.
compute_channel_depth(channelmask, depth[, ...])	Compute channel depth from a mask and section.
compute_surface_deposit_time(data[, surface_idx])	Compute the time of last deposition for a single time.
compute_surface_deposit_age(data, ...)	Compute the age (i.e., how much time ago) the surface was deposited.
shaw_opening_angle_method(below_mask[, ...])	Extract the opening angle map from an image.
