Опыт создания глобальной цифровой базы данных по Гипсометрической карте Мира в масштабе 1:15 000 000. Первые результаты

Аннотация

Geointormation systems application opens new prospects in the geomorphological analysis and mapping. A global digital data base on the relief designed for the geoinformation systems may be formed using the new World Hypsometric Map (scale 1:15 000 000). As an example of this data base usage, morphometric characteristics of southern continents (Africa, South America, Australia, Antarctic) are computed and discussed. The continents' area, volume, mean height as well as area and volumes of individual altitudinal steps were calculated in the automatic regime within the geographic and geological-geophysical boundaries of the continents.
