Classify Snow/Ice Pixels with Threshold

[RobinGummels]

Description:
Implement Step 7: Classify every pixel with NDSI > 0.42 as snow/ice.

Tasks:

• Apply threshold: snow_ice_mask = NDSI > 0.42
• Create binary mask (True/False or 1/0)
• Count total number of snow/ice pixels
• Calculate percentage of snow/ice pixels in candidate cell
• Visualize classification result overlaid on satellite imagery
• Save classification statistics

Acceptance Criteria:

• Binary classification mask is created
• Percentage of snow/ice pixels is calculated
• Classification aligns with visual glacier features
• Statistics are logged for analysis
