Release Notes for Version 1.2.1

Merging dev-20241014 to main by @Tschoun

New Features

Enhanced VHI Calculation

• Added functionality to mask snow-covered areas and low illumination angles in VHI calculations.
• Introduced a new function calculateSnowMask to compute the Normalized Difference Snow Index (NDSI).

Improvements

Snow Coverage Masking

• Implemented masking for areas with NDSI values of 0.43 or higher, effectively filtering out snow-covered regions.

Illumination Angle Filtering

• Added masking for areas with illumination angles of 65° or higher to improve accuracy in poorly lit terrain.

Technical Details

• The new calculateSnowMask function utilizes NDSI for snow detection.
• Threshold values:
  • NDSI: ≥ 0.43 for snow coverage
  • Illumination angle: ≥ 65° for low light conditions

Notes

This release significantly enhances the accuracy of VHI calculations by accounting for snow coverage and low light conditions. Users should expect more reliable results in areas prone to snow or with challenging lighting conditions.
