Commercial and open source GIS packages enable users to generate their own spatial information. One way to do this is through a process known as digitizing. In the example below, aerial imagery is used as a reference to identify potential sites suitable for solar panels on public properties.
I also edited OpenStreetMaps to include some of the buildings that I identified above on their website. Here is a screenshot of some contributions: notice the two red buildings below, which I have identified on Open Street Maps as public, borough property.
By importing information not referenced to the Earth’s system, GIS users have the possibility of exploring spatial relationships for fictional representations. One example of the Hundred Acre Woods is shown below.
