Sometimes it is more convenient to have a digital copy of an aerial photograph. Having a photograph as a PDF, TIFF, or JPEG gives the user the power to highlight particular areas of the photo or otherwise manipulate it using programs like Adobe Photoshop. There are many websites that host collections of aerial photographs; the list on this page shows some that could be useful.
Different sources have different policies about data sharing. Be aware that while some aerial photographs are free and readily available for download, others require payment or will just show an index and ask patrons to visit the library in person. Other resources may show photographs that are not available for download. However, these are still useful for research purposes.
Nearmap is a subscription service that provides current, high resolution aerial maps. Maps are available for view in the browser-based interactive web mapping application, as well as for download.
