[Talk-cz] dalnice, silnice I a II tridy: nyni v .osm formatu

[Pavel Machek]

Ahoj!

Tak jsem si trochu hral s konverzi... a myslim ze uspesne. Data od
Help Service jsou _mooc_ pekna. (I kdyz asi o 100 metru posunuta proti
osm, coz jde snadno opravit).

Konverzni skript je v priloze, vysledek starsi verse je na 

http://atrey.karlin.mff.cuni.cz/~pavel/outgoing/result.osm.bz2

Ten osm vypada zhruba: ... teda pro plny data je posledni way cislo
212605.

Vyhovuje takhle source odkaz?
