Short Summary

This paper proposes a generalized enhanced snow/ice index derived from Landsat imagery to improve the accuracy of snow and ice mapping, specifically targeting mountainous regions.

Objective

• To develop and validate a generalized enhanced snow/ice index using Landsat imagery for accurate snow and ice mapping in mountainous areas.

Study Configuration

• Spatial Scale: Mountainous areas; specific spatial resolution not provided but implied by Landsat imagery.
• Temporal Scale: Not specified in the provided text.

Methodology and Data

• Models used: A generalized enhanced snow/ice index (specific algorithm details not provided).
• Data sources: Landsat imagery.

Main Results

• The study developed a new generalized enhanced snow/ice index.
• This index is designed to achieve accurate snow/ice mapping in mountainous regions. (Quantitative results are not available in the provided text.)

Contributions

• Development of a novel, generalized, and enhanced snow/ice index.
• Improvement in the accuracy of snow/ice mapping in complex mountainous terrain using Landsat imagery.
