2.1.2 Slant-Range vs Ground-Range Geometry Selection

[Yuvraj198920]

As a SAR processor
I want to choose between slant-range and ground-range coordinate systems
So that I can work in the geometry appropriate for my analysis

Acceptance Criteria:

• -oo GEOMETRY=SLANT_RANGE or GROUND_RANGE option
• Default behavior documented
• Slant-range: raw pixel coordinates (azimuth time, range time)
• Ground-range: via GCP interpolation to lat/lon
• Consistent across all burst selections
• Examples show both modes

Tasks:

1. Implement geometry selection logic
2. Add slant-range coordinate exposition
3. Implement ground-range transformation via GCPs
4. Document coordinate systems
5. Create usage examples
