PhillyHistory + augmented reality as a smartphone app

This is the first in a series of posts about several exciting new projects that my old friends and Philly GIS happy hour buddies are up to at Azavea.  The first is funded by an NEH Digital Humanities Start-Up Grant that was awarded to the Philadelphia Department of Records to create a smartphone app that will enable users to view historic photos from PhillyHistory.org draped over the current modern-day landscape.

If the research proved successful, users would be able to point their smartphones, using the camera view, at a building or other location and see historic images of that same location.  The photos would be accompanied by descriptive information from PhillyHistory.org with additional explanatory text provided by local historians.  This combination of technology and history could be a powerful tool for showing the lengthy and interesting history of Philadelphia.

Click here to read more about the project.  Azavea expects to make the app (for iPhones and phones running Android) available as a free download sometime in the next few months.  A white paper about the project will also be released this spring and could hopefully serve as both inspiration and a springboard for faculty and/or student projects at Bucknell (where we have a wealth of historical images and GIS data for Lewisburg).

NYT map graphic on toxic contamination from natural gas wells

The New York Times has put out a new interactive map graphic that visualizes toxic contamination found in the wastewater from natural gas wells in PA.  The data – from 149 wells – is visualized by the type of contaminant (radium, uranium, gross alpha and benzene) and the amount by which each well exceeded the federal drinking water standard.  Below are some screenshots from the interactive graphic.

Radium contamination:

 

Uranium contamination:

 

Gross alpha contamination:

 

Benzene contamination:

Bucknell student uses ArcGIS in research on sleeping sickness

Below is an interview with Daniel Dougherty ’12, a History and Geography major, discussing his use of GIS for an analysis of the impact of climate change on sleeping sickness.  The research project was conducted as part of Prof. Duane Griffin’s Geography 204 course Applied GIS. In the interview, Dougherty describes the data and methodology he used for the project and talks about some of the conclusions he drew from his analysis.

The images below show some of the maps Dougherty was able to produce using ArcGIS, MaxEnt and data from WorldClim.

New conservation and Marcellus Shale-related data available on Xanthus GIS Server

Several new datasets from Platts (an energy consulting firm) and the Nature Conservancy were added to the GIS Data folder on Xanthus last night.  The data includes gas compressor stations for PA, NY and WV along with current and projected locations of Marcellus Shale wells and wind turbines in PA.  Forest patches and landscape blocks are also included in the data from the Nature Conservancy . Full metadata is available on Xanthus. Bucknell faculty and students – please contact me for access and/or additional information on the new datasets.

Data from Platts:

Gas compressor station locations for PA, NY and WV.

Datasets from TNC’s Pennsylvania Energy Impacts Assessment:

Projections by The Nature Conservancy and Western Pennsylvania Conservancy

  • Probability surface of conversion to Marcellus Shale development
  • Projected Marcellus Shale pad locations under low, medium, and high development scenarios

Marcellus Shale drilling permits from the PA Department of Environmental Protection (PA DEP)

  • Drilled, valid, and expired Marcellus well permits as of January 2011
  • Drilled Marcellus Shale wells only as of January 2011

Projections by The Nature Conservancy and Western Pennsylvania Conservancy

  • Probability surface of conversion to wind energy development
