Mapping alpine glaciers changes from space
IEEE International Geoscience and Remote Sensing Symposium, 2003This paper presents the results obtained from the analysis of a set of multitemporal Landsat images for the study of the status of the Italian Alpine glaciers. A fuzzy set based classification technique has permitted the identification of snow and exposed ice in glaciated areas.

SOME PROBLEMS OF GLACIER MAPPING EXPERIENCED WITH THE 1:10 000 MAP OF THE ALETSCH GLACIER
Canadian Journal of Earth Sciences, 1966The difficulties of the aerial survey of the Aletsch Glacier lay in establishing ground control in the high mountains and locally on the moving glacier surface, and in plotting featureless névés on the autograph. The major problem in plotting proved to be the delineation of the margins of active glaciers where marginal zones were thickly covered with ...

<p>One consequence of current and likely future melting of high mountain glaciers is the development of glacial lakes. Their evolution over time has implications for future water supplies in arid mountains and for the timing and magnitude of glacier hazards, such as Glacial Lake Outburst Floods (GLOFs).</p><p&

THE PURPOSE OF GLACIER MAPPING
Canadian Journal of Earth Sciences, 1966As an introduction to the Symposium on Glacier Mapping and for the purpose of providing a basis for further discussion, the requirements in various types of glacier maps are differentiated. Most maps of glaciers are not made specifically for glaciologists but as part of a general geographical survey program.

Canadian Journal of Earth Sciences, 1966
The history and problems of mapping in Greenland are briefly reviewed, with particular reference to the Indlandsis (the Ice Cap) and the glaciers. The author calls for greater collaboration between the glaciologist and the topographer, and cautions against placing too great reliance on the present maps for calculations of the volume of the Indlandsis.

Glacier Mapping and Monitoring Using Multispectral Data
2014Multispectral 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.

Lakes, Rivers And Glaciers / A Map Commentary
Cartographica, 1968The map entitled Lakes, Rivers and Glaciers is the first of a new series that will supplement the National Atlas of Canada presently in production in the Department of Energy, Mines and Resources, Ottawa. The purpose of this series of separate map sheets is to make available a limited amount of new material in periods between the publication of atlas ...

CARTOGRAPHIC REPRESENTATION AND SYMBOLIZATION IN GLACIER MAPPING
Canadian Journal of Earth Sciences, 1966In glacier cartography, as in all mapping, questions of convention and standardization have long plagued cartographers. National and international efforts at standardization have generally failed. To assess the styles, techniques, and status of glacier representation, several hundred maps of glaciers and related features were examined and evaluated ...

MEASURING AND MAPPING OF GLACIER VARIATIONS
Canadian Journal of Earth Sciences, 1966One of the main purposes of glacier mapping is to determine the temporary state of glaciers and to investigate glacier variations by successive mappings. The author illustrates this work with particular reference to terrestrial photogrammetric surveys of mountain glaciers in the Nanga Parbat region of the Himalaya and of the Tunsbergdalsbre in ...
