Аннотация:In the paper we perform the World Digital Glaciological Atlas “Snow and Ice on the Earth as a main part of the system of glaciological data management developed in the Institute of Geography Russian Academy of Sciences in Moscow. This Atlas is based on the World Atlas of Snow and Ice Resources published in Russia. The maps in the Atlas are underpinned by a vast data bank on snow cover and ice that has been collected from all over the world over the second part of the XX century. Most sections carry materials from hydrometeorological observations reduced to long-term averages by the standard techniques. Many types of glaciological maps are original and have been specially compiled for the Atlas. The digital Atlas based on GIS techniques and can serve as the basis for glaciological monitoring and broad regional studies arrangements. The system of glaciological data management provides data access, generates an environment for data integration, gives opportunity to use GIS techniques for glaciological data analysis. Data integration technologies are designed to form a single information space of the subject areas of spatial data. The object of integration are information resources on glaciology, stored in distributed system of data on web servers and geoportals of Institute of Geography RAS in a form of databases and metadata, structured data files, object data files, electronic atlases. The result of integration of glaciological data technology application is a series of software and technology solutions. The digital and web-atlas "Snow and ice of the Earth," is an example of open source spatial data on glaciology in the multiprogram environment.
