Glacier retreat monitoring from SAR coherence images: application to Gangotri glacier

SPIE Proceedings, 2016
Retreat of glaciers is an important phenomenon to be monitored as they have a direct bearing on flow of water in rivers and rise of water level in sea. Use of Synthetic Aperture Radar (SAR) images in glacier dynamics studies has been gaining interest in the recent years.

Snow, Glacier, and Glacier Lake Mapping and Monitoring Using Remote Sensing Data

2021
Nowadays, remote sensing (RS) technology under the space programs of the world’s leading agencies provides multispectral optical and microwave data for natural resource mapping of the Earth’s surface. Snow and glacier mapping are critical for the accurate assessment of water resource availability on the Earth’s cryosphere and to quantify the impact of ...

Glacier Mapping and Monitoring Using Multispectral Data

2014
Multispectral satellite data represent the primary data source for spaceborne glacier mapping and monitoring, and remote-sensing studies have generated significant results regarding global glacier observations and understandings. In this chapter we provide an overview of the use of multispectral data and the methods typically applied in glacier studies.

Glacier change monitoring using optical satellite imagery: the case of Forni Glacier

2023
Glaciers are one of the most important indicators of climate change. Monitoring their evolution is, therefore, crucial for safeguarding the Earth’s ecosystem. In this study, exploiting photogrammetric optical satellite processing techniques, we used image pairs from Ikonos-2 and Plèiades-HR satellites to generate Digital Surface ...

Summary of International Glacier Monitoring Summit

2011
To answer questions about linkages between changes in glaciers and climate change—e.g., How much of the current global sea-level rise can be attributed to melting glaciers?—more precise and quantitative studies of glaciers are required. This includes systematically extending the available in situ and remote sensing data, putting together a more ...

Monitoring the World's Glaciers—the Present Situation

Geografiska Annaler: Series A, Physical Geography, 1981
A review is given of the historic development of the Permanent Service of Fluctuations of Glaciers started in 1968 and the World Glacier Inventory started in 1975.

Glacier monitoring and glacier-climate interactions in the tropical Andes: A review

Journal of South American Earth Sciences, 2017
Abstract In this review, we summarized the evolution of glacier monitoring in the tropical Andes during the last few decades, particularly after the development of remote sensing and photogrammetry. Advantages and limitations of glacier mapping, applied so far, in Venezuela, Colombia, Ecuador, Peru and Bolivia are discussed in detail.

Monitoring glaciers from space using a cubesat

IEEE Communications Magazine, 2015
The Ecole Polytechnique de Montreal and the University of Bologna recently collaborated to develop a nanosatellite mission in the context of the 2012–2014 iteration of the Canadian Satellite Design Challenge, an inter-university competition intended for the development of space expertise among graduate and undergraduate students.
