In 2011, the staff in the University Map Library re-constructed the 1955 street network for Waterloo County. In 2017, the staff at the Geospatial Centre updated the project with 2016 data, allowing scholars, historians and community residents to study and analyze past and present street patterns.
To visualize the changes which have occurred within the Waterloo Region multiple web maps were created to showcase the urban growth, road network, and road name changes between 1955 and 2016.
Available through both Scholars GeoPortal and the Geospatial Centre, this imagery covers approximately 37,290 square kilometres in eastern Ontario and was collected in leaf off conditions between April 28th and June 7th, 2014. Imagery is available in 1 km tiles. Data resolution is 20 cm.
Using ArcGIS Online's storybook application, you can see the increase in Waterloo's population over the years. The historical maps that were used to create the population density maps can be seen in the storymap.
The Geospatial Centre now has complete coverage of these digital orthoimages for Lambton County (west of Middlesex County). These full colour images were flown in April 2002 by J D Barnes and originally provided to the Geospatial Centre by the Ministry of Natural Resources in October 2004. Pixel resolution of these images is 30 cm.
Story Map "Swipe" and "Spyglass" is an ArcGIS online application that enables users to interact with two web maps or two layers. The Geospatial Centre uses this application to give a visual comparison between historical airphotos and maps with the present.
