Record #200039:

An automated scheme for glacial lake dynamics mapping using Landsat imagery and digital elevation models: a case study in the Himalayas / Junli Li, Yongwei Sheng.

Title: An automated scheme for glacial lake dynamics mapping using Landsat imagery and digital elevation models: a case study in the Himalayas / Junli Li, Yongwei Sheng.
Author(s): Li, Junli.
Sheng, Yongwei.
Date: 2012.
In: International Journal of Remote Sensing. (2012.), (2012)
Abstract: Discusses importance of glacial lakes in alpine regions as indicator of climate change, and difficulty in mapping these over large areas using remote sensing, because of confounding factors such as mountain shadows and melting glaciers. Presents automated mapping algorithm based on hierarchical image segmentation and terrain analysis to delineate glacial lake events. Each glacial lake is delineated with local segmentation value and topographic features from digital elevation model are used to discriminate mountain shadows and glacial lakes. Uses scenes from Landsat Thematic Mapper/Enhanced Thematic Mapper Plus (TM/ETM+) from 1990, 2000, and 2009 to test algorithm and examine changes in glacial lakes in Himalayas.
