But few of us are willing to loan our slides, even to our closest colleagues. Duplicate slides are never as good as the originals, and there is no practical way to include location and subject captions with the slides. Frequent use exposes a slide collection to possible damage or loss. So an individual's slide collection is really only accessible when he or she can personally present it. The Solution Digital storage of photographic images, and their distribution over computer networks, solves many of these problems.
Duplication is easy, cheap, and the duplicates are identical to the originals.
Degradation and loss are no longer an issue. Captions can be stored in databases associated with the images, providing sorting and searching capabilities that would be almost impossible otherwise. Collections can be shared over the internet with colleagues, or with strangers. If you have an educational project that could make use of Geo-Images materials, please read the section on Conditions for use of these images. Lisa Hamilton managed the project, compiled database information, and processed the images.
