  • Challenge - access
  • Challenge - funding
  • Contain over two million photographic images chronicling the last 150 years of the city’s history
  • They document and illustrate the cities growth and development
  • How it was built
  • [pause]
  • But also everyday scenes
  • Such as schools
  • Workplaces
  • This graphic shows the differences in the two water cycles. Notice the increase in run off between the natural area and the urban area.
  • We selected a variety of factors that contribute to sustainability, ranging from location in a state or federal tax incentive zone to environmental amenities like tree canopy to transit considerations like access to bus and regional rail lines. Retail businesses targeting markets may be interested in demographic factors like age and per capita income and proxies for environmental engagement like recycling participation.
  • Many of the ideas here are not new. Actually, they were developed here in Philadelphia by Ian McHarg, who was chair of the Landscape Architecture and Regional Planing department at the University of Pennsylvania
  • Now fast forward to the 1990’s. We’re interested in digital maps. This approach to compositing several digital maps was developed further by Dana Tomlin, who is now also a professor at University of Pennsylvania. Tomlin developed the computational vocabulary to perform this type of work – he called it Map Algebra. He’s also a really great teacher, so if you ever get a chance to take a class with him. Do it. He’s great.
  • So, these days people do this kind of work using desktop GIS systems. You are looking at the ArcMap application from ESRI
  • scenarios
  • Heat map

    6. 6. Our story starts in the City Archives, where the collections present challenges…
    7. 7. The first of which was ORGANIZATION . With images stored in boxes based on the city unit they represented (Streets, Schools, etc.), finding any particular image was a significant challenge.
    8. 8. The second was PRESERVATION . The oldest negatives are combustible, and newer ones are prone to warping.
    9. 9. The third was ACCESS . To access an image, a visitor would have to go to the archives and have a valid research reason for entrance. Approximately 100 people per year did this.
    10. 10. Certain images and/or photos on this page are the copyrighted property of 123RF Limited, its Contributors or Licensed Partners and are being used with permission under license. These images and/or photos may not be copied or downloaded without permission from 123RF Limited The last was FUNDING . Addressing these challenges was unlikely to be an inexpensive endeavor.
