Russian Arctic Coastal Landscape Map With Coded Polygons

This dataset is a 1:4,000,000 scale geospatial map of landscape polygons for the Russian Arctic coastal zone. It contains polygons attributed with an eight-character LAND-ID code describing zone, landscape, lithology, and substrate chemistry. The map was created by NSIDCV0 and is available on multiple government data platforms.

Use Cases

• Classifying Arctic coastal landscapes by zone, lithology, and substrate chemistry using the LAND-ID attribute.
• Analyzing spatial patterns of glacial and wetland landforms across the Russian Arctic.
• Delineating boundaries between major river basins and island complexes using the large enclosing polygons with LAND-ID=0.
• Mapping soil and terrestrial ecosystem distributions (e.g., alpine tundra, lacustrine wetlands) for regional environmental studies.

Strengths

• Provides a detailed, multi-factor landscape classification via an eight-character LAND-ID code for each polygon.
• Covers the entire Russian Arctic coastal zone at a consistent 1:4,000,000 scale.
• Available on multiple authoritative platforms (NASA Earthdata and Data.gov), indicating vetting and importance.

Limitations

• Specific row/polygon count, file size, and complete column details are unavailable across all sources.
• Some areas, like smaller islands (e.g., Zemlya Frantsa) and far eastern portions, have no LAND-ID codes assigned.
• License information is inconsistently reported as 'other-license-specified' or null.
