After a number of requests over recent years for such files, we
have at last made a useful attempt, and in 2015 expanded and updated
all the data. They have been tested in the field by two
"volunteers" when doing the 40-mile Challenge on Sunday 17th
They have now been updated. All are invited to test the new
files in practice for the Apr-2015 event!
Those wishing to try them on their PC might like to load them
into Google Earth, or just open them in notepad?
To follow, including how they were created, and discussion
As a first draft, back in
2010, I reproduce below the contents of an email I sent to one
of our users (who has a Garmin/Sporttracks3 set-up which needs
1. Your File
Soon after receiving it I loaded it into Google Earth, and
found it faithfully reproduced all the points exactly as in my file
you based it on. A bit later I opened it in Notepad and found that
the big differences were:
- Your files are based on a <trk> <trkseg> with lots
<trkpt lat="xxx" lon="xxx">
- My files are based on a <rte> with lots of
lat="xxx" lon="xxx" />
Is this the feature which makes it work in your
2. OSM & Lonvia Hiking
I had used my original file to create much of the the route on
OSM, and viewing this in Waymarking
Trails: Hiking Maps
I wondered if this was a
good route for preparing gpx files. The resultant gpx files are the
same basic format as yours, but without the <ele> &
<time> tags. However my biggest problem of using that method
was that it increases the number of points due to extra points where
a junction to another path, a change to embankment, cutting, bridge
start, bridge end, etc is added to the basic OSM source data. It
also started and finished in Church Lane for some reason!
3. Updates of ACW route, and how shown on Bing Map
A significant number of minor changes have been made to the
Bing map since the base version for the gpx file you used was
created. These included :
- "Corrections" to make the route more accurate due to
comparisons with gpx files recorded by a few users on 2011
Challenge, reports of errors by users, etc.
- For 2012 Challenge we will be using the Connect2Kenilwoth new
bridge and route across Kenilworth Common. This has now been added
to the Bing and OSM maps.
- "Optimisations" to reduce the total number of points without
reducing the map as an adequately accurate representation of the
path. This helps to speed use of the Bing Map, but more
importantly reduces the size of the gpx file - a significant
request from many who attempted to use it. My original GPX
file had over 2000 points, reduced to 1295 on the version you
used. It is now down to 959, even after adding a detailed
representation of the K2K path.
4. What should be the requirements for a gpx file?
Many variables are involved. A few I note are:
- <trk> or <rte> or <???> structure?
- Header data - are there any "rules" so all can use it?
- Number of points maximum.? ACW can't be represented by much
less than 1000, but one user believes his device has a specified
limit of 500, but it worked with the 650 odd some utility had
reduced it to (BUT it seemed to have reduced by missing out about
every other point, so in some places was potentially useless as a
guide of which way to go!).
- Size of file. This could logically be as significant a
limitation as number of points. Any guidance?
- Any naming of points recommended? The first attempt I created
included naming of Start, Start of each of the 17 other maps,
names of the 7 Check Points. This would seem useful (or maybe
essential if some wish to do the challenge without using the Green
Book!). It also made a very attractive Google Earth picture!
- Other variables?
- Reference Guides already available? I have so far failed to
find any - who should I ask?
Can anyone else
help? Paragraphs below discuss further.
read and offer advise!
5. Short Term Proposals
I suggest for "immediate" actions:
- I have published my current 1520 point
<rte> version (Mar-2015)
- If you could convert this to your <trk>
version for 40-mile route, I will publish that as
- Better still, tell me how to covert files so
I can tell others, and maybe convert a full set of mine to the
most popular format?
I will also add appropriate notes, and maybe much of above in
the "Details" at the end, PLUS make the gpx news item a permanently
linked page on the website!
6. Longer Term Proposals
In the medium term, if you let me know how to do the
conversion, I will publish any future updates in both
In the longer term, I hope to determine a more robust process,
including giving advice to users! This will include searching for
Sporttracks to see if this educates me on another little
I might even buy a GPS device so I can get practical
experience! I have been waiting till a full system is available on a
SmartPhone, so I can have all the goodies in one device - it's bound
to arrive soon, but maybe not this Xmas?
- My wife had a Nexus 7 Tablet for a Xmas present in 2012 - I
set it up for all the features she required, but also added the
Essentials" app. This works superbly as a
device for recording tracks, which can be exported as gpx files
and viewed in Google Earth. I've used it to checkout paths
and update my maps - but it adds yet another variant of GPS
- I downloaded to my PC an application GPSBabel
. This supports about 180 formats! ... plus some 17
Filters to choose sub-sets of fields, plus lots of Tables &
Examples. As well as reforming the format, GPSBabel can
do useful things like reducing the number of points in clever ways
which make it a lot lower number of points but virtually the same
accuracy. I did a quick test, but still intend to
explore more later.
- During the last few weeks of Feb-2013 I updated all ACW maps
with detailed route changes to be included in the Green Book for
Challenge 2013, and aligning all paths to the newer and more
accurate Bing aerial maps recently published. These maps
(available at all zoom levels except the largest scale) also bring
Bing and Google maps in line with each other for accuracy, so GPX
files loaded from or to either give virtual identical
- I will use the data from 3 to update above gpx files
- Any further input on "best" format to publish would be
Updated lonvia files added, incorporating all changes in the
Feb-2014 Green Book, plus significant changes to some circular walks
Any further input on "best"
format to publish would stll be very welcome? ... preferably
with advice on how to produce that format &/or help to do so
Nothing new on technology used, but all data updated and more
Nothing new on technology used, and no gpx data needed
updating. I have however downloaded the latest version of GPSBabel
which works with Windows 10 and has even more features to explore -
I must find time, but would also like to hear from users!
