Jaws677 Posted November 28, 2017 Posted November 28, 2017 Guess its a rookie mistake, I didn't think it would be sold out already!!Same here . Even after also missing out on the Soweto marathon
Paddaman Posted November 28, 2017 Posted November 28, 2017 "Elevation databasesIn the past, we consulted public elevation databases to determine the elevation at each point in the activity. The resolution of these databases varied based on location and we were not able to control for the many errors in these databases. We now have an elevation look-up service powered by data from the Strava community. Each activity that is uploaded from a device with a barometric altimeter is used to build the new Strava elevation basemap. "Somehow I trust the Garmin TOPO SA mapset more, as I have seen many errors with the Strava basemap. PS : What did your ascent show before the elevation correction - IIRC the 920 XT uses a barometer?If elevation statistics are your fetish, then the only way to get it correct is to muse over a 1:50 000 topographic paper map. All the gadgets are guides. The most accurate remains the surveyor general

The DEM actually carry elevation data on each 'pixel'. OK let's get back on track... Edited November 29, 2017 by Pieter-za
Pulse Posted November 28, 2017 Posted November 28, 2017 It is The SA Topo map is a digitised version (++) of exactly those Surveyor General (whatever the new entity is called) maps. The DEM actually carry altitude info on each 'pixel'. OK let's get back on track...How/where can one access this?
Pieter-za Posted November 29, 2017 Posted November 29, 2017 How/where can one access this?Hi Pulse It is this product: https://shop.navworld.co.za/topo-southern-africa-v3-pro.htmlhttps://buy.garmin.com/en-ZA/ZA/p/536642 The DEM is really cool - some examples of capability attached:(Ferret69 - LUT is your track )
dave303e Posted November 29, 2017 Posted November 29, 2017 USGS also has some ok DEM's if you want a free option, for smaller areas you can get the NGI aerial imagery from their offices for free and with the trig beacon and spot height data use photogrammetry to extract a pretty good DEM for areas too big for a Drone but too small for a plane.

SwissVan Posted November 30, 2017 Posted November 30, 2017 It's been not bad so far... But I'm not in the Alps!Well I’m not quite in the alps either although I do see lots of snow on the surrounding high ground and alps in the distance..... but geez it’s the cold (max temps a few degrees above zero) and darkness that’s so unmotivating... Suppose I’ll get into once my recently tanned skin falls off due to the low humidity..... ????
