In order to qualify for inclusion in the SOTA scheme, a summit must have a topographic prominence of least 150 meters (termed P150) (or exceptionally, for summits in regions of especially low prominence, 100 meters, or P100). Ascertaining the exact prominence of candidate summits can be a time-consuming and painstaking task, depending on the information (usually maps) available. After they are identified and verified as meeting the prominence requirement, their local name and exact elevation still need to be determined before they can be assigned a SOTA reference number.
Some of the initial work can be done automatically using software that analyses digital elevation models. This is by no means sufficient, but provides a very useful starting point for many regions.
Accessible software tools for this task include LandSerf and Winprom. Unfortunately, these programs require more memory than usually available on common computers to analyse areas the size of many countries. This often reduces the availability of the analysis results for people interested in identifying and validating SOTA summits.
In an effort to overcome at least some of the difficulties in identification of candidate summits, I have developed an experimental software, SRTMprom, that focuses on identifying summits meeting a given prominence requirement using publicly-available high-quality topographic source data, requiring as little memory as possible to get the job done.
Some of the results are presented on Google maps here.
- pages that provide searchable and sortable lists of the SOTA summits
- Google Maps for every SOTA region, with the latest information about each summit
- .gpx files that can be used to transfer the summits coordinates to a GPS as waypoints
- .kml files that can be used with Google mapping products like Google Earth
The information presented here is obtained from the official SOTA database, which is the only valid reference. The pages and files are updated every day.
These pages work much faster with the Google Chrome browser...
