This unit introduces the idea of a GIS database serving as a project or archive database, contrasting it with the traditional geographic archive, the map library. It discusses issues of data currency, justifying the need for digital geographic archives, suitability of data for archiving, platforms, distribution, user interface and costs vs. benefits of digital archives. It illustrates these issues with several examples of spatial data archive systems.
