Description

1.0.0 readiness: Hydrology routing

Area: Hydrology Functions: flow_direction, flow_accumulation, flow_length, flow_path, watershed, hand, stream_order, stream_link (d8/dinf/mfd)
Source: xrspatial/hydro/

Scope
  • Public surface frozen against the README feature matrix
  • Dark-corner decisions resolved (see #2930)
Sweep clearance, no CRITICAL or HIGH (accuracy and security first)
  • Accuracy /deep-sweep xrspatial/hydro
  • Security
  • Performance
  • API consistency

Last swept: none yet

Examples
  • Notebook example
  • (optional) standalone script
Linked bug issues
  • #2796 (High) flow_path_dinf hangs forever on cyclic D-inf flow directions
  • #2885 (triage) Extend lazy MFD dask assembly to stream/hand modules and study the convergence phase

Research direction

Start in xrspatial/hydro/ and review the listed routing functions against the README feature matrix. Read the dark-corner decisions in #2930, then inspect the deep-sweep scope and linked issues #2796 and #2885. Done means the public surface is frozen, sweep findings have no CRITICAL or HIGH issues, and the notebook example is complete.
