1910 Sanborn Swipe app now available!
The MCLIO, in partnership with the AGSL, has georectified the 1910 Sanborn Fire Insurance maps of Milwaukee County. This raster dataset was created by taking high resolution scans of over 900 large-format sheets, georeferencing, and then mosaicing them together. These incredibly detailed maps are still used today by environmental surveyors, historians, and urban planners; now they have been made more accessible than ever. We are now offering this raster dataset as a service, and you can take a look at it with our Sanborn Swipe App located here! This app can also be found on our homepage at http://county.milwaukee.gov/mclio under the maps tab.
