Abstract
The purpose of this study is to create a unified geodatabase of containing information on relict (continental) dunes. Continental dunes are widespread in Eurasia and North America. In the studies by many authors, a considerable amount of information regarding the distribution of continental dunes, their morphology and lithology of sediments has been obtained. This information requires unification and systematization. The study proposes the structure of the “Relict continental dunes” multilevel geodatabase. The principle of territorial display of aeolian forms has become a priority in concept of geodatabase development. The geodatabase consists of five major relational multilevel blocks. The advantage of proposed geodatabase is the coverage of a large amount of information about the objects under study and ability to quick analysis it with the spatial display of the research object. The main tool for building the geodatabase is ArcGIS Desktop 9.0. The geodatabase structure uses a variety of RS and cartographic data processed by GIS, field surveys and laboratory analysis methods. Overall, geodatabase contains systematic, geocoded and layered raster, vector and text, data types in SHP, MDB, GRID/IMG, and TIN formats.
