Description:

Abstract:

The Stratified land-use/land-cover layer displays vegetative cover in rural areas and distinguishes portions of urban and suburban areas still containing and retaining some potential as habitat. This was created by mathematically combining the Urbanized land with the Vegetative land cover.

Purpose:

Part of the Pennsylvania Gap Analysis progression, this dataset was designed to facilitate the interpretation of Pennsylvania's surface vegetation and habitat models for vertebrate species in the Commonwealth.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Orthophotos for random locations throughout the state were used to check the land cover analysis. Analysis for areas obscured in original satellite imagery and other areas selected at random or because of problem in satellite analysis were verified through aerial videography or physical inspection.

Verification still in progress (as of August, 1999).

Quantitative_Attribute_Accuracy_Assessment:

Attribute_Accuracy_Value: Unknown

Attribute_Accuracy_Explanation: n/a

Logical_Consistency_Report:

Gridded dataset. The current dataset was derived from LandSAT Thematic Mapper imagery. Because of variance in image dates and times there may be slight discontinuities in the land cover analysis.

Completeness_Report: Complete coverage for the state of Pennsylvania.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report: verified through overlay with orthophotos.

Quantitative_Horizontal_Positional_Accuracy_Assessment:

Horizontal_Positional_Accuracy_Value: 210

Horizontal_Positional_Accuracy_Explanation:

This value is an estimate in meters based on potential registration errors introduced by shifting the TM data to match ancillary data.
