Landscape Map of the Russian Arctic Coastal Zone

Summary

The map consists of ESRI Shapefiles of landscape polygons (in landscape unit types) for the Russian Arctic coastal zone (scale 1:4,000,000). The map is based on a digital circumpolar Lambert projection map. Polygons have a single attribute ("Land-id"). Land-id is an eight-character code that describes the landscape unit. The first two digits code zone, the third and fourth code landscape, the fifth through seventh code lithology, and the eighth codes substrate chemistry. The code is described in detail in an accompanying legend. Data are available via ftp.

2. Detailed Data Description:

Format:

The map is in a vector format stored as ESRI Shapefile spatial data format. The Shapefile is most easily imported into ESRI's ArcView, but most other GIS packages can import Shapefiles. ESRI also provides a free basic GIS package, ArcExplorer, on the ESRI web site.

The Shapefile consists of three files: ggd613_landscape.dbf (attribute data), ggd613_landscape.shp (feature geometry) and ggd613_landscape.shx (feature geometry index). All three files have been compressed using gzip.

Map polygons have a single attribute ("Land-id"). Land-id is an eight-character code that describes the landscape unit. The first two digits code natural climate zone, the third and fourth code altitudinal and morphological zones, the fifth through seventh code lithology, and the eighth codes bedrock composition. The code is described in detail in an accompanying legend (in comma-delimited ASCII).

Large polygons enclosing islands, or continental land areas between major rivers, form the boundaries of many smaller landscape polygons. These large enclosing polygons have Land-id values of 0. Some smaller islands (e.g., Zemlya Frantsa) have no codes associated with them. Areas on the far eastern portion of the coverage also have no code.

File Size:

The ESRI Shapefiles range from 10.5 KB to 1.2 MB. The ASCII legend file is 3 KB.

Spatial Coverage:

The map covers the entire Russian Arctic coastal zone, from 50 to 90 deg N and 15 to 169 deg E. The map projection is Lambert-Azimuthal with WGS 84 datum.

Parameter or Variable:

This data set consists of landscape units in polygons: natural-climatic zone, altitudinal and morphological zones, lithology, and bedrock composition.
