A new automatic approach for extracting glacier centerlines based on Euclidean allocation [PDF]

The Cryosphere, 2021
Glacier centerlines are crucial input for many glaciological applications. From the morphological perspective, we proposed a new automatic method to derive glacier centerlines, which is based on the Euclidean allocation and the terrain characteristics of

A new global dataset of mountain glacier centerlines and lengths [PDF]

Earth System Science Data, 2022
The length of a glacier is a key determinant of its geometry and is an important parameter in glacier inventories and modeling; glacier centerlines are the lines along which the main flow of glaciers takes place and, thus, are crucial inputs for many ...

The Randolph Glacier Inventory: a globally complete inventory of glaciers [PDF]

Journal of Glaciology, 2014
Abstract The Randolph Glacier Inventory (RGI) is a globally complete collection of digital outlines of glaciers, excluding the ice sheets, developed to meet the needs of the Fifth Assessment of the Intergovernmental Panel on Climate Change for estimates of past and future mass balance.

A regionally resolved inventory of High Mountain Asia surge-type glaciers, derived from a multi-factor remote sensing approach [PDF]

The Cryosphere, 2022
Knowledge about the occurrence and characteristics of surge-type glaciers is crucial due to the impact of surging on glacier melt and glacier-related hazards. One of the super-clusters of surge-type glaciers is High Mountain Asia (HMA).

The Glacier Inventory of China [PDF]

Annals of Glaciology, 2009
AbstractFollowing recommendations from the International Commission on Snow and Ice for a world glacier inventory, an inventory of glaciers in China was carried out by Chinese glaciologists from 1978 to 2002. Each glacier was measured from aerial photographs and topographical maps and 34 parameters recorded.

Inventory of glaciers and perennial snowfields of the conterminous USA

Earth System Science Data, 2023
Abstract. This report summarizes an updated inventory of glaciers and perennial snowfields of the conterminous United States. The inventory is based on interpretation of mostly aerial imagery provided by the National Agricultural I magery Program, US Department of Agriculture, with some satellite imagery in places where aerial imagery was not suitable.

An estimate of global glacier volume [PDF]

The Cryosphere, 2013
I assess the feasibility of using multivariate scaling relationships to estimate glacier volume from glacier inventory data. Scaling laws are calibrated against volume observations optimized for the specific purpose of estimating total global glacier ice
