Dear Alain and others
Thank you so much for the positive comments. I must admit I was surprised and delighted to receive the invitation from the MT and I hope that some of my work will make life easier and more productive for all those involved in identifying and classifying summits.
In brief, as well as the work I have done (and reported in the news) identifying activation zone statistics using SRTM data, I have used the same data and some GIS software to analyse the topography of various regions. One of the queries that can be done is to ask the software to identify peaks with a minimum elevation and prominence (even as two separate variables).
This generates a relief map with all qualifying summits visible. A careful review process follows to identify them. I have used this to not only check and verify existing summits but also identify some potential P100 summits in certain areas.
The process I use is not so complex but it can be time consuming (but less so than working with many maps) so I am investigating another more sophisticated method that should generate such lists automatically… but this is still in progress.
One caution I would add about the SRTM data is the fact that is is fine to use for analysis of relative elevation but do not rely on it for absolute elevation information. It is likely give results that differ from official survey elevation data. Also there are some voids and errors in the data so any results should be carefully checked.
So, yes I will be discussing this with AM’s in the appropriate forum and hopefully you will all be seeing some interesting and positive activity regarding the objective review and selection of summits in the future.
I look forward to some exciting work…
