Abstract:

Land Cover data (circa 1990's) was compiled and crosswalked between U.S. and Canadian data sources to yield a regional dataset representing 13 major land cover types. These types include the following: Inland Open Water/Ocean, Low-High Intensity Residential, Commercial/Industrial/Transportation, Bare Rock/Sand/Clay, Quarries/Strip Mines/Gravel Pits/Peat Bogs, Regenerating Forest, Deciduous Forest, Conifer Forest, Mixed Forest, Shrubland, Agriculture/Plantations/Cultivated, and Forested Wetland, Emergent Herbaceious Wetlands. The input datasets which represented a variety of spatial scales were resampled to a pixel resolution of 30m x 30m cell.

Purpose:

The main objective of this project was to generate a generalized and consistent land cover data layer for the entire Northern Appalachian Ecoregion. Land Cover data (circa 1990's) was compiled and crosswalked between U.S. and Canadian data sources to yield a dataset representing 13 major land cover types. The resultant land cover dataset can be used as a layer in a geographic information system (GIS) for any number of purposes such assessing wildlife habitat, water quality and pesticide runoff, or land use change.

Attribute_Accuracy_Report:

No formal accuracy report has been assembled for this dataset. The variety and accuracy of attributes in the input datasets ranged greatly from sources with from 10's to over 50 land cover classes. Please request the document "TNC_Comprehensive NAP Land Cover Definitions GK 2_03.xls" for more information on how the input attributes were crosswalked to the simplified 13 land cover types.

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

No formal accuracy report has been assembled for this dataset. Data sources range widely in their resolution and accuracy. Input data source spatial scales ranged from 1:10,000 forest stand data to 30m Thematic Mapper satellite derived land cover.

Process_Step:

Process_Description:

The attribute classes in the input datasets were studied to create the crosswalk between the input classes and the final 13 simplified land cover classes. Please request the document "TNC_Comprehensive NAP Land Cover Definitions GK 2_03.xls for information on which classes in each input dataset were lumped into each of the 13 resultant classes. After vetting the crosswalk with the state and provincial representatives on the TNC Northern Appalachian Ecoregional Planning team, the input datasets were gridded into 30x30m pixels and merged to create the simplified regional land cover dataset.
