OS Maps API Notes

November 9th 2021 Release Notes

The elevations data panel and mini-graph shown when viewing a British GPX file have been updated to use OS Terrain 50 elevation data rather than SRTM data. The reasons for this are explained in the new OS Terrain 50 page, which developers might be interested in. Also, the site has undergone a much-needed content update, internal sort-out, de-lousing, and fumigation. So please let me know if anything which used to work is now broken (email address at the bottom of this page).

The new not-so-good stuff:

If the changes made have broken something you used to rely on, then perhaps try OS Maps, which is terrific value for money. It has all the online OS features you will likely ever need, including plotting & viewing saved routes and importing & exporting GPX files.
