We have just updated the GPS mapping app so that it is now running on the latest version of our mapping software. This is a complete rewrite to use the Leaflet mapping library in preference to OpenLayers which previous iterations of the software have used. Leaflet provides a much more stable, and more lightweight, foundation for the app. The aim in writing it was to produce a new app which looked similar to the old one - to make it easier to move over to using it - while adding new functionality.
You should find it very similar to the old app but there are some significant changes:
As part of this change you now select the map tiles being displayed by putting your mouse over the new "layers" icon in the top left corner of each map. We are currently offering you:
WayMaps - our own British Isles mapping, which we continue to update and improve.
Ordnance Survey - these are now sourced directly from OS rather than Bing so it's correctly oriented with north being straight up. We're also now getting two levels of zoom (8 and 9) at 1:25K rather than one as well as two levels (6 and 7) at 1:50K. As before these tiles are only available to users who are logged on.
NLS Historic OS - these tiles are based on Ordnance Survey maps from 1919-1947 and are provided to us by the National Library of Scotland map service. These tiles are only available to supporters and can be interesting when you're researching a route you're intending to walk, especially to see where roads and railway lines used to run. Be warned that the register is sometimes less than perfect so don't plan your route directly on these tiles, instead use "2 maps" mode and put WayMaps or OS on one map and this on the other.
OpenStreetMap - this is OpenStreetMap's own tile server. Probably not that useful in general as our WayMaps has most of their relevant geodata on it but you might want to refer to it occasionally.
Bing aerial photography - only available to users who are logged on.
ESRI aerial photography - only available to users who are logged on.
The top bar functionality has changed slightly in other ways too so for example:
clicking on the WalkLakes icon top left takes you to the site home page rather than hiding the top bar. This seems more intuitive for new users however we've retained the ability to hide the top bar and you now click on the icon in the top right hand corner to do that.
We've removed the "track mode/route mode" button and replaced it with a more intuitive pair of radio buttons for editing track or route.
There also a host of smaller changes. For example:
When viewing WayMaps tiles then for zoom 7 to 9 the grid squares are numbered on the left and along the top (in the same style as OS's blue numbers every 10km, but drawn dynamically so they're always in view).
Talking of zoom levels the level number is now displayed top right between the '+' and '-' zoom buttons rather than in the top bar as in 2 map mode one map may sometimes be in a different zoom level to the other.
layers (water levels, OS benchmarks, photos, and tops) are now called "overlays" but work exactly as before
When displaying a track then if you've turned on direction arrows these are rendered rather more elegantly.
Printing has been improved (and we've also fixed a bug where printing didn't work at all on Apple Macs, iPads, or iPhone).
If you are logged in then you can choose, in "Settings" to have ascent and descent in both the route and track summary boxes to be displayed in feet rather than metres.
