OSM (OpenStreetMap )
OSM now includes ACW and all linked/shared Long Distance
paths
See http://hiking.lonvia.de/?zoom=12&lat=52.40651&lon=-1.53815&layers=FFBTT
for result.
Background
At the Godiva Festival we were asked for information/help to get
ACW on OSM (OpenStreetMap - the Open source map of the world, nor
including virtually all streets and increasing details of buildings,
woods, footpaths, etc.).
I was able to cover ACW very fast, initially just providing the
gpx file, then by checking/correcting/improving the result.
OSM already had Heart of England Way and Centenary Way just about
complete, but very little for Millennium Way or Shakespeare's Avon
Way, so I added the parts of these shared with ACW, then linked the
shared bits and extended them some distance beyond. After that
I added ACW Circular Walks, and part of North Arden Heritage
Trail/Parish Walk Fillongley. Together this gives a good map
of the network closely linked with ACW.
What you can now see:

many footpaths all over UK, Germany and spreading
worldwide |
... find out by
looking! |
Using above link you see the footpaths on a background of the
default OSM street view, with the named walking routes highlighted
and labelled with an abbreviated name.
If you open an OSM user account, you can open the editor and see
with a background of a Bing Aerial map - but take care not to edit
and save anything by mistake!
Other viewing tools are available or being developed, but I know
of none worth recommending just now - but search for yourself, and
let me know if you find one others may find useful!
Guide to using Lonvia
Zoom
Use the + or - or the slider on zoom bar at top left of map area,
or scroll wheel on your mouse. Hint - when you zoom in with
the mouse, first position the pointer near the area you wish to
zoom to but on the side nearest the map border of the
area - as the area you want gets near the centre, move cursor to
centre of area you want and continue zooming.
Pan
Left click and drag. If you want to move a long way, zoom
out first, then pan, then zoom in
Routes Button
Zoom in to the area you want to see in more detail, and then
click ROUTES at bottom-right of map area, then:
- Click the Full Name of the walk you want to read more details
about. Not only can you read details, the route gets
highlighted in Yellow (... and even if the only bit in sight is in
the corner of the map, hidden behind the details panel! ).
You can zoom or pan to see it all or the bit you want.
- The detail panel checks the distance mapped as well as showing
the distance claimed.
- If the length is defined as (e.g. for NAHT - North Arden
Heritage Trail "length=26 mi") it converts this to km and
shows both near the top. In this example Length: 41.8km
(mapped: 14.3km) meaning that I have mapped the bottom 14.3 km out
of the 41.8 km/26miles total.
- You can also check for errors - I found Centenary Way has been
given data as "le3ngth=100 mile" which gets shown but not
converted to km". I also found that for PWF (NAHT Parish
Walk Fillongley) I had put "length=6 miles" which it also ignored
- it only understands mi ! (I have of course corrected these
- but tell me if you find others)
- You will also notice that the ACW Circular Walks have distance
issues. Sometimes it is simple rounding (Cyril rounded to
nearest 0.5 km); sometimes re-use of part of the route for outward
and return legs (e.g. C18 Watery Lane leg); but sometimes probably
Cyril got the basic measure wrong?
- Use Back to route list link if you want to see above examples,
and note that as you zoom and pan the list in the Routes in Region
gets updated.
- When you've had enough of this detail close Routes in Region
pane (click x in TR corner of panel)
Pan & Zoom to see other areas. As you zoom in you get
more detail. As an example try C02X (ACW
Circular Walk 02X (eXtra to visit Berkeswell Windmill)) - zoomed out
and you won't even see it named! Zoom in and you will see the
Windmill. Zoom in more and you will see it even the windmill
named, and note that the driveway to it is coloured red because it
is a private road! I will add a comment that it is only open
on the first Saturday from April to October - or at least it was in
2005 - do you know the current status? When open? Has it got
its sails back on (I seem to remember reading they were being
repaired)?
gpx Button
On the route pane for each route, you will also find a gpx
button. Click this and you can download gpx file for that
route. This gpx file may then be loaded to your GPS mobile
device, and you may be able use it to help find your way!
There are a few possible issues with gpx files produceed this
way:
- They are in an unusual format. They do however load into
Google Earth OK, so this may not be a problem.
- They will have more points than needed, because each path or
road junction adds extra points, as do every change of surface,
embankment or not, bridge or not, etc. For the 40-mile route
his means you currently get about 1150 points derived from Lonvia,
compared to less than 970 for the same detail of
route derived from Bing.
- Lonvia gives the route clockwise, not in order drawn as from
Bing.
I will do a few more tests, then load some samples on http://www.acoventryway.org.uk/news-gpx-files_01.htm and
consult experts soon.
Other Buttons
DON'T click Hike & Bike Map link - that's just an
acknowledgement of the site where they get the optional Hillshading
from. Similarly for some of the other links in the borders
Settings
if you want to see Hillshading, click the white + sign in the
blue semicircle at Top Right of Map area, then change Hillshading
from 0% default - 100% makes Coventry and the rest look a bit like
the Hike & Bike map. More useful to try maybe to change
Route Layer to the default I get of 80% or whatever you like
best.
