The Wisconsin Historical Society maintains the Wisconsin History and Architecture Inventory (AHI), consisting of approximately 120,000 properties surveyed by architectural historians or preservation consultants. The inventory has been assembled over a period of more than 25 years from a wide variety of sources. In many cases, the information is dated and properties may be altered or no longer exist. The majority of properties included in this inventory are privately owned and not open to the public. After 25 years of data collection, there are numerous difficulties with inaccurate addresses. Nearly 10,000 properties have errors, which makes it difficult to map out using a geocoder and have to be entered manually and validated with primary and secondary online sources. I will share how Historic Preservationist are using GIS and what online resources I use to validate and find historic sites from the past.

    Discovering Lost Buildings Discovering Lost Buildings Presentation Transcript

    • Lost Buildings Using GIS and online Maps to Geolocate Historic Structures.  Michael Bricknell Wisconsin Historical Society Historic Preservation Specialist [email_address]
    • My Task:
      • To update the Wisconsin Architecture and History Inventory (AHI).
      • Geolocate 10,000 properties which have incomplete addresses.
      • Examples:
          • NW CNR of Front St and Spring St
          • CHURCH ST (no postal number)
          • Gov't Lot #6 - Red Ceder Lake
          • (or a blank address)
      • Share what free resources I have found useful in locating properties with little information.
    •  
    • SOURCES
      • Paper Maps (Historic and Current)
      • County Geographic Information Systems (GIS)
      • Aerial Photography (Oblique and Vertical)
      • Library of Congress - American Memory Maps (LOC)
      • Bird's Eye maps (LOC and HistoricMapWorks)
      • Sanborn Insurance maps (not free online, but useful)
      • Geographic Names Information System (GNIS)
      • Photo Service Websites (Flickr, Photosynth, PicasaWeb)
      • Wisconsin Architecture & History Inventory (AHI)
      • 1. Check the Wisconsin Architecture & History Inventory (AHI) for any information. (address, plss, physical description, is it demolished?) ~120,000 records
      • 2.Validate the address, if it has one, on the County’s GIS website.
      • 3. Check the address in Google Maps - Street View and Bing Maps - Bird's Eye View (if available).
      • 4. If no address or conflicting results, I need to validate it with a primary or secondary resources.

    • Conclusion
      • 3 years ago this would not have been possible. New and innovative web services have been developed.
      • No traveling required!
      • As more historical collections become available online the easier it is to validate a resource.
      • County GIS data is vital and essential to what I do.
      • What will be next?
