Forests, Water and People Analysis

ORIGINAL DATA SETS

These geographic information system (GIS) datasets were used in the original Forests, Water and People Analysis using the 1992 National Landcover Dataset.
In order to access these raster and vector data files, you will need a GIS software package such as ArcGIS 9 or ArcView. You can download a free copy of ArcGIS Explorer to view these data here.

STEP 1

• Percent forest land by watershed
• Percent agricultural land by watershed
• Percent riparian forest cover by watershed
• Road density (quartiles)
• Soil erodibility (k factor)
• Housing density (2000; acres per housing unit) by watershed
• Ability to Produce Clean Water

STEP 2

Surface drinking water consumers per unit area. (Not available for download. See DWPOP field in final dataset.)

STEP 3

• Percent private forest by watershed

STEP 4

• Development pressure per unit area
• Final Watershed Data

UPDATED DATA SETS

These geographic information system (GIS) datasets have been updated since the original Forests, Water and People Analysis was published. 

2001 Update

This dataset follows the same analysis method as the original analysis, however uses the 2001 National Landcover Dataset. 

• Ability to Produce Clean Water
• Final Watershed Data
  

2001 with HUC-12 Update (12-digit HUC)

This dataset follows a slightly modified methodology as it not only uses the 2001 National Landcover Dataset, but summaries each step by 12-digit HUC or subwatershed, rather than the 8-digit HUC or subbasin.  In addition, an updated road density and riparian forest cover dataset was created using new data.  See the methodology document for more details.

• Ability to Produce Clean Water
• Final Watershed Data
• Methodology for the HUC-12 Update
