Google and Tomtom

maps.google.com has a new feature. If you get directions, you can drag the route around, making an iternerary.

The link can be turned into a file for the Tomtom

I have put this online. The code is there as well and can be placed on other sites.

Have fun

You can also use TYRE - available here

Tyre is a great program, however there are some differences.

First Tyre runs on Windows, which I do not have, so I can't run it.
Second it is based on Google Earth, while the site relies on Google maps. Google earth is a program you need to run on your PC, google maps you can use when on the road in e.g. a internet cafe.

This means when I am e.g. in Spain, where I do not have my PC with me, I just go into a place where there is a PC, determine my route, save it my Tomtom and be on my daily route again.

Also I can use it at my place where I work and am not allowed to install Google Earth.

Again, Tyre is most likely a great program. This one is just different and intended for thos who do not want/can use Tyre.

That looks SO cool!

Bang goes work for the rest of the day, while I play with it!

OK... First thing I've found.... Moving the start and end points a bit (as per instructions) is important, but what you need to do is click and drag the TOP of the green and red "flags" rather than the bottom - that just adds another intermediate step.

Secondly. It doesn't make it very clear that the URL you need is got by clicking "link to this page" in the top right. Copy that into the script and it seems to work!

Hi
This does look useful, thanks.
Basically it's great, but I have had the following issues with it (in IE7 on XP MCE if that matters):
- It's not showing negative values as negatives, so longitudes West are coming out as the correct number but East. The same might happen for latitudes South, but I haven't tried them.
- It's adding an unwanted ~ then spaces and two carriage returns at the end of its output. This one is easy to ignore when you copy and paste the results, but I haven't tried to see what it does in TomTom if you include it.
Hope this helps.

Hmmm...
Seems you're right Barry.

The test itinerary I did at work (my normal route home) LOOKED fine - all the place names were right, but I had no GPS signal so it wouldn't show me a map of the route (another TomTom annoyance but that's another story).
When I went outside and tried to follow it home, all the waypoints were over in East London rather than West.

Seems someone has left out a minus sign somewhere in that code.
I'm not sure where 'houghi' got it. Is it from Google themselves, houghi? Who do we contact to tell them it's NEARLY so good but has this problem.

I'm not using IE, so it doesn't seem to be a browser thing.

I got the same result. Anything west of the meridian is wrong.
Seems to be due to the use of preg_replace to remove the + or - signs.

Shame because it looks promising.
I think he wrote it himself..

In Notepad, I just added a minus sign at the start of each line and it solved the problem.

Change lines 63 & 67 in tomtom.php

$x = preg_replace('/[\+\-]/', '', $loc[1]);
...
$y = preg_replace('/[\+\-]/', '', $loc[2]);

To

$x = preg_replace('/[\+]/', '', $loc[1]);
..
$y = preg_replace('/[\+]/', '', $loc[2]);

Put the html and php files on your own website and click on the html file.

The ~ and two extra CRs at the end appear to be spurious lines on the end of tomtom.php

The code is corrected in both the file you download and the site itself and I hope that the site is a little bit clearer as to what to copy where.

I have also added thanks to the person who actualy wrote the code.

Thanks everyone.
I just tried to implement the corrections myself using Notepad, and it wasn't working for me, so you've saved me some detective work.

I think you are all damned clever! Not Worthy

houghi - you have a PM

Shame that Google Maps limts the itinerary to 90 or so waypoints. I tried plotting a road navigation rally which uses many country lanes and hundreds of turns.
