_sev. What do you mean exactly with: "and then wrote a simple Perl script to transcode all names into Latin alphabet." ? Do you mean transliteration? Now where did you put the result? In name:en ? You are not supposed to put transliterations there. Leave it empty if you do not know the right English name or if there is not a real translation.

Bedankt Freek. Dat is precies wat ik zocht. Ik heb er bericht van gemaakt. Ook Jan O. bedankt voor de steun.

Sorry but I still see no parameters for

void convertPoint(double x, double y, double & rx, double & ry)

How did you call it was my question. Like:

double x = 12.23;
double y = 34.56;
double rx;
double ry;

convertPoint ( x, y, rx, ry );

and the result would be values in rx and ry

and the error would occur in that function.

You are showing all kinds of in and output that for me
has no connection to that functin.

You make it impossible to help.

First the file MText.cpp is nowhere under the TwoNickels link.
Then you give the code for function convertPoint() but you do not show the parameter values when you call it.
You are not telling on which statement the error occurs.
And what is the error message? What has lat lon to do with calling convertPoint() ?

Besides that you could embed an osm map with the track like is done here:
osm.org/browse/relation/299748

Sorry glebius. I have only heard of JOSM but never used it. I make my own programs. The only thing that's missing in that url are some parameters. Please give some full working urls. For instance how to get tiles. Or a link to the used api.

Very nice. But how to use these links? With the first a bbbox parameter is expected and then..
With the second a green jpg appears...

Where is info how to use them?
