[1.0.0] Surface basics

[brendancol]

1.0.0 readiness: Surface basics

Area: Surface Functions: slope, aspect, curvature, hillshade, northness, eastness, sky_view_factor
Source: xrspatial/{slope,aspect,curvature,hillshade,sky_view_factor}.py

Scope

• Public surface frozen against the README feature matrix
• Dark-corner decisions resolved (see [1.0.0] Scope freeze: reconcile dark corners #2930)

Sweep clearance, no CRITICAL or HIGH (accuracy and security first)

• Accuracy /deep-sweep xrspatial/slope.py
• Security
• Performance
• API consistency

Last swept: none yet

Examples

• Notebook example
• (optional) standalone script
