Land Cover v0.4

This 1km land cover dataset represent highly modified output originating from the Alaska portion of the North American Land Change Monitoring System (NALCMS) 2005 dataset as well as the National Land Cover Dataset 2001. This model input dataset was developed solely for use in the ALFRESCO, TEM, GIPL and the combined Integrated Ecosystem Model landscape scale modeling studies and is not representative of any ground based observations.

Use of this dataset in studies needing generalized land cover information are advised to utilize newer versions of original input datasets (2005 NALCMS 2.0, NLCD), as methods of classification have improved, including the correction of NALCMS classification errors.

Original landcover data, including legends:
NLCD 2001

Final Legend:

value | class name

0 | Not Modeled
1 | Black Spruce Forest
2 | White Spruce Forest
3 | Deciduous Forest
4 | Shrub Tundra
5 | Graminoid Tundra
6 | Wetland Tundra
7 | Barren lichen-moss
8 | Heath
9 | Maritime Upland Forest
10 | Maritime Forested Wetland
11 | Maritime Fen
12 | Maritime Alder Shrubland

Methods of production:

Due to specific models' land cover input requirements, including the fact that each model is primarily focused on different descriptive aspects of land cover (i.e. ALFRESCO considers land cover in respect to how it burns, TEM considers land cover in respect to how it cycles carbon through the system, and GIPL considers land cover with respect to its influence on the insulative qualities of the soil).
