…from the Spring 2009 issue of ArcNews

Highlights:

  • Using ArcGIS Desktop software, the NREL team can determine the most favorable locations for wind farms.
  • GIS-based modeling enables analysis of terrain, which significantly impacts the quality of wind at a particular site.
  • The primary audience for these maps is government decision makers.

Map of the Day: Determination of Potential Aquifer Recharge Zones Based on Soil Permeability and Slope, Butte County

…from the ESRI Map Book, Volume 24

“Some of the feature characteristics of potential aquifer recharge zones are soil permeability values and steepness of slope. In other words, water will tend to sink into the ground more readily in areas where the soil is more permeable and the slope is level or nearly level.

“Soil permeability values and slope steepness values can be represented as layers in a GIS for further analysis. A new layer (Potential Aquifer Recharge Zones) can be created by combining the soil permeability values with the slope steepness values.
