Searching and visualizing OpenAerialMap imagery interactively
OpenAerialMap (OAM) provides openly licensed satellite and unmanned aerial vehicle (UAV) imagery. Currently, it has over 12,400+ images around the globe. This notebook demonstrates how to search and visualize OAM imagery interactively. You can download images automatically with one line of code.
Uncomment the following line to install leafmap if needed.
