Integrity Logic has released Geograph VA ($4.99, available here), the latest in its series of GIS (Geographic Information System) apps for the iPhone and iPod touch. The new app covers the Commonwealth of Virginia and features over 45 layers of geographic data which can be combined and merged. Geograph VA can use the iPhone's built-in GPS and the iPod touch's location service, and can also capture high-definitions maps, which can be retrieved from the device's photo album.

Like its 19 sister applications covering 22 states, Geograph VA contains a wide array of data layers:

  •  
    • geological map from the U.S. Geological Service
  •  
    • public land ownership (local, state, federal)
  •  
    • states outlines
  •  
    • land elevation from NASA
  •  
    • ocean bathymetry
  •  
    • old faults
  •  
    • over 5,800 named features (summits, tunnels, cliffs, bridges, etc...) with link to USGS web site for each feature
  •  
    • hydrologic units
  •  
    • ecological regions from EPA
  •  
    • counties with link to Census data
  •  
    • UTM zones, township and range, USGS quadrangles
  •  
    • congressional districts with links to representatives' web sites
  •  
    • urban areas, hydrological features
  •  
    • cities, roads and railroad tracks
  •  
    • active mines and quarries
  •  
    • zip codes - potassium/argon dates
  •  
    • surficial material - main aquifers
  •  
    • over 4,400 mineral resource data points with link to USGS web site for each resource

    You can also download a number of additional layers for the application. Because Geograph VA is a self-contained app, users do not need Internet access to access its GIS information.
