Hello pharo-users community,

my name is Nicolas and I am a student of Informatics at USI in Lugano. I am currently working on my master thesis and I am getting into pharo, playing around a little bit and tasting the potential that is hidden in pharo.
I recently saw a tweet from mr. Serge Stinckwich about how to build 2d buildings and rivers with the openstreetmap API and roassal as drawing support. I tried to replicate the code since I would like to play with it but I got some errors that I didn't menage to fix.
So I was thinking to ask here if anyone has such code to share.

Thanks in advance.
Cheers,
Nicolas
