Below are major articles which explain the concepts of prominence, cell maps, map datums, etc. used throughout the encyclopedia. To go with these articles, there is a annotated index or glossary which focuses on the key terms themselves. So if you run across a term like 'key saddle', you can get a refresher. This prominence glossary project was carefully planned in order to contribute to efforts to standardize the terminology used in various other prominence websites. Since then, the terminology have been generally accepted by the prominence community and have been propogated by others to Wikipedia. Here is a brief document of my original Terminology Plan.
Prominence is a measure of how separate a mountain is from the nearest higher peak.
Prominence cells is a method of defining regions based on the boundaries between mountains of a given prominence.
