this post on Practical Ed Tech. Pic4Carto is an interesting site that I will probably add to that list in the future.
Pic4Carto is a site that lets you browse for street level images (don't call them Streetview because that is specific to Google Maps) all over the world. The vast majority of the images found through Pic4Carto are labeled with a Creative Commons license. The images come from Flickr, Mapillary, and the Wikimedia Commons.
To find images on Pic4Carto you simply have to zoom-in on a location until you see a grid appear over the map. Once the grid appears you will see a number inside each square. Those numbers indicate how many pictures are available for that area. You can then click on the number to see the images (be patient because it takes a minute to load).
Applications for Education
Pic4Carto could be a good tool for students to use to find images specific to a place that they are studying in a geography or history lesson. I can see myself using it when teaching current events to show students what a place that they are reading about in the news looks like.
