    Hello John, 

     

    thanks for your reply. It's a pitty that this is not possbile as a measurement is more accurate than a calculation upon a more ore less precise model. But if there's nothing to be done about this we have to accept it.

     

    Have a nice weekend.

    Hi Lucas,

    I'm sorry, there isn't a way for you to substitute the SRTM data we use with your own elevation data. We took a decision very early on when developing the site to use a global dataset for elevation profiles rather than GPS data, as although it isn't perfect, it offered the most reliable and consistent data source. It would be very difficult for us to change this now, as it's a core part of the design of the site. As a workround, you may find that the tweaking the problem part of the route slightly may help.

    Hello, 

     

    I just recognized that the elevation profile of a route seems to be calculated by some elevation data source (SRTM I guess). As my navigation device records elevation data as well it qould be better to show the recorded data -espacially when the route is situated in very hilly landscape or mountains. 

    An example: https://www.plotaroute.com/route/925534

    You can see a steep downhill followed by a steep uphill section at km 12,5 to km 13 which is not present at all in reality. I guess it's caused by a rough elevation model or by inaccuracy when matching the GPS position with the elevation model as the street is situated just at a cliff with large elevation differences 10m left or right of the street.

    Is it possible to tell plotaroute to use my recorded elevation data instead of any elevation model?

     

    Best regards,
