Masking operations

The package makes available routines for masking out planview attributes of the delta.

This class is defined in deltametrics.mask.

Note

When Mask objects are instantiated with single time-slice x-y planform data (i.e., L x W data), the returned mask is expanded along the first dimension to return an object with dimensions 1 x L x W. This ensures that all Mask objects will have the same number of dimensions, but may lead to confusion if writing your own functions.

Mask classes

BaseMask(mask_type, data)	Low-level base class to be inherited by all mask objects.
ChannelMask(velocity, topo[, …])	Identify a binary channel mask.
WetMask(arr[, angle_threshold, is_mask])	Compute the wet mask.
LandMask(arr[, angle_threshold, is_mask])	Identify a binary mask of the delta topset.
ShorelineMask(arr[, angle_threshold, is_mask])	Identify the shoreline as a binary mask.
EdgeMask(arr[, angle_threshold, is_mask])	Identify the land-water edges.
CenterlineMask(channelmask[, is_mask, method])	Identify channel centerline mask.
