Electronic cartographic GIS models of the environmental state of the Dniester canyon

The Dniester Canyon is a deep gorge, 100-120-140 m, between the Podil Upland on left bank and Carpathian Prut-Dniester Uplands right bank. canyon famous for its classic geological sections of Silurian Devonian systems, which there gradual transition. There are only four such incisions in world: ours, as well Czech Republic, Scotland United States. Great geomorphological attractiveness canyon: two Upper Pleocene supra-canyon five Quaternary intra-canyon river terraces; caves, waterfalls, travertine formations, bizarre rocks physical chemical weathering. rocky flora fauna protected by natural monuments, reserves, regional landscapes national parks. These objects listed Red Green Books. Therefore, was chosen one seven wonders nature. That why it necessary to preserve this heritage present future generations. To do this, environmental safety systems developed GIS mapping methods. electronic cartographic material geoinformation digital or vector maps. Vector maps created based registration raster scanned map satellite images. layers can be interpolated from thematic using databases. Most often, measuring operations packages implemented form special functions presented separate menu item. Such include: measurement (determination) point coordinates; distances specified coordinates (with without taking into account three-dimensional coordinate system); length straight broken line; perimeter polygon; area landfill; volumes surface cutting plane. Selection help user get exactly information he needs at moment working with GIS. selection part more databases carried out queries.
