Abstract:
The 2005 land cover for Pennsylvania was created through a mix of
interpretation of remotely sensed data and use of ancillary data sources.
The date actually is a mid-point as the remotely sensed and ancillary data
are representative of the time period 2003-2007.

The coding is based on the Anderson Land Use/Land Cover system, where the 
more descriptive detail in the category is reflected by a higher code value.
Further the coding is hierarchial so that each group can be related to other
codes within a general category.  For example, in the Anderson system the general 
classification of forest is a 4, a deciduous forest is 41, and so on.  For a 
description of the Anderson system see;

This project was funded by The PA Department of Conservation and Natural Resources (DCNR)
Purpose:
State wide land cover will provide a reference for current land use status in the state for tracking changes in urban land as well as serving as an input for hydrologic and non-point pollution modeling and assessment.

 124 - Airports


21 - Row Crops
24 - Pasture/Grass
 241 - Golf Courses


41 - Deciduous Forest
42 - Evergreen Forest
43 - Mixed Deciduous and Evergreen

50 - Water

61 - Forested Wetlands
62 - Emergent Wetlands

70 - Bare; Unclassified Urban/Mines, Exposed Rock, Other Unvegetated Surfaces
 750  - Active Mines/Significantly Disturbed Mined Areas

 

The creation of the land use data varied by the different groups and can be summarized in this way;

Roads - Roads were taken directly from the Pennsylvania Department of Transportation road layer where a
  subset of the mapped roads were placed into the final product.  The roads were selected by relating 
  the roads that were detectable in satellite imagery to their width described in the road layer attribute
  table. Roads of greater than 20 feet were used in the final output.  

Residential/Institutional/Industrial/Commercial Land: Airports: Golf Courses: Active Mines - These areas were 
  visually interpreted using the USDA NAIP imagery, with a minimum mapping unit of 2.0 hectares (5 acres).  
  The tree cover was established by classification of satellite data.

Forests/Water/Row Crops/Pasture/Grass - Interpreted from multi-date satellite data, using some mix of supervised
  unsupervised classification algorithms. Water was also taken from the NWI wetlands layer to remove some of the 
  problems such as classification of exposed rock as barren, and misclassification of darker evergreens.

wetlands - These were taken directly from NWI, which was recoded to be similar to other land cover products as NLCD.
