Definition: Topographic prominence of peak in meters
Drafted on: 2009-09-28

Topographic prominence of a natural=peak in meters.

Rationale

Prominence (or prime factor ) is a objective measurement of how independent/important a peak is. "Peak baggers" are often very concerned with this number.

Prominence can be used to select peaks for rendering. A scheme which can work both for Denmark and Switzerland, would be: If too many peaks to render within a area at a zoomlevel, select the ones with highest prominence. Different thresholds should be used for peak symbol only, versus render peak with the name.

Example

  • name= Mont Blanc
  • natural= peak
  • note= any one know the quality of coordinates ?
  • name:it= Monte Bianco
  • ele= 4810.90
  • prominence= 4695
  • name:fr= Mont Blanc

Further extension

A Relation peak:prominence could be define to relate a peak to its "key col" and to its "parent peak"?
