two feature requests

1) multiple routes on one map. Often I have a Garmin file with way to many points to convert to one TomTom ITN file. Se I start decimating and it would be very nice if I could easily check if some critical point is removed which changes the route. If I would have the original route and the decimated routes together in route converter it would give an easy check.

2) display google maps routes using html links like this one (example):

http://maps.google.nl/maps?f=d&source=s_...=UTF8&z=12


Thanks for all your time and effort.

I recently found this javascript option. I wanted to have a look at that one but I have too much other things on my head right now.

I think I understand the intention to preserve critical points when reducing a track but I have no idea how to realize it. For me, the Douglas-Peucker Algorithm works fine to reduce a track and afterwards I'm adding waypoints which I want to visit if they're missing.

Try dragging the url into RouteConverter or saving a position list as "Google Maps (*.url)". Isn't that what you're searching?

Is it possible to store the array of lat/long points into a secondary "backup" array and build an "Undo" function for the route?
If you remove one (or more) point(s) and you end up with a route you don't like, you use the "Undo" button to restore from the internal backup array and start again.
If you have removed a number of points, you (can) save the route, (after saving) RouteConverter synchronizes the "new" array with the backup array and the user can start removing more points.

(Simple) Work around:
My work around is to remove points, save them to a temporary route, remove more points and save again. if removing more points suddenly leads to a "wrong" route I simply reload the previously saved temporary route and start again.
Once I'm satisfied with the route I save it and give it it's definite name.

(That's a little more work than the "Undo" button/function and takes moe time).

Yes, it is, but there seems to be a bug in the url drag and drop. The track which looks in Googlemaps like screenshot1.jpg looks in routeconverter prerelease 6 June like in screenshot2.jpg. I wasn't planning on a transcontinental trip :-).

This is the URL
http://maps.google.nl/maps?f=d&source=s_...=UTF8&z=12

That is because I don't know how to decode the geocode-Parameter of the URL. Thus some coordinates are missing and I try to geocode them - which is sometimes wrong.

I'm not asking for any kind of automation. I'm happy with the current tools for decimating a track into a route. Having the original route visible on the background would make it much easier to manually add points at certain critical locations to make sure that the decimated route matches the original track. Deviations are easily spotted if two different colored lines diverge.

You could use different position lists for this. Add the option to duplicate a position list. And add for each position list the check box option "show on map". Then you could start decimating one position list and keep the original position list visible as the reference.

[routeconverter]

You could use different position lists for this.

The reason why I denied implementing this is that

• the number of positions is limited due to browser instabilities
  
• thus the number of positions per positionlist that could be used to represent a positionly would be significantly (i.e. visibly) reduced
  
• it's hard to design a UI that's understandable for first time users
  

Add the option to duplicate a position list.

Did you try the prerelease which allows to copy-paste all positions of a position list (i.e. into another position list)?

And add for each position list the check box option "show on map".

That's a good idea addressing the first of my objections listed above. The others still remain.

Currently I think a decent undo/redo functionality could be sufficient, too. What do you think?

[bekker]

Copy and paste works fine. That would remove the need to duplicate the position lists.

If you could add the "show on map" checkbox and a undo/redo option I think that would be very help full in the decimation of tracks. Would it be possible to show routes on the map with a certain degree of transparency?

And is the geocode problem with the google maps URL solvable?

It is possible but currently I'm limiting the number of positions that can form a route to 22 segments of 42 positions. Adding "show on map" checkbox means I have to divide this number by 2,3,4,5 for each route displayed.

And is the geocode problem with the google maps URL solvable?

As long as only Google knows how to decode the geocode parameter: no. Here is a workaround.
