Novi croatia.poly / New croatia.poly

Jučer sam kontaktirao Geofabrik [URL1]. Frederik Ramm mi je poslao croatia.poly koji oni koriste za dnevni croatia.osm.bz2 (10M) [URL2] ekstrakt. Usporedio sam ga sa sa granicom te vidio da na nekim mjestima ulazi u RH tako da ekstrakt nije čitava RH. Već ranije sam kreirao croatia.poly na bazi granice, ali sa pomakom 1km prema van tako da je čitava RH stala unutra. Preuredio sam taj .poly tako da je što bliže granici, da je što manji broj točaka, a da je ipak cijela država unutar njega. Poslao sam ga nazad Frederiku, dobio odgovora da će koristiti ovu verziju [URL3], te da ujutro provjerim jeli sve ispalo kako treba. Jutarnja provjera je prošla super, čitava država je unutra, nema više isjeckane granice. Hvala Frederik.

Nakon uspjeha sa Geofabrik ekipom okrenuo sam se na Cloudmade [URL4] ekipu te im poslao istu verziju croatia.poly. Njihova verzija [URL5] nije ni blizu granicama kao ona od Geofabrik ekipe te je njihov croatia.osm.bz2 (18.6M) [URL6] ekstrakt dosta lošiji. Oni su koristili seriju pravokutnika koji bi trebali predstavljati površinu države, ali dobrim djelom fulaju te dobrim djelom obuhvaćaju okolne države. Čekam njihov odgovor.

PS. Volim kad mogu pomoći i ispraviti netočne podatke :D

I contacted Geofabrik [URL1] yesterday. Frederik Ramm sent me croatia.poly they use for daily croatia.osm.bz2 (10M) [URL2] extract. I compared it with Croatia border and saw that it enters into Croatia in some places and extract is not whole Croatia. I created croatia.poly based on the border earlier, but with 1km offset outward so whole Croatia was inside. I modified that .poly so it comes close to the border, so it has as few nodes as possible, and that whole country is inside. Sent it back to Frederiku, got reply that they will use this version [URL3], and to do a quick check to see it is ok in the morning. Morning check went great, whole country is inside, no more hacked up border. Thank you Frederik.

After succes with Geofabrik team i turned to Cloudmade [URL4] team and sent them the same croatia.poly version. Their version [URL5] was not even close to the border as Geofabrik team one was, and their croatia.osm.bz2 (18.6M) [URL6] extract is far worse. They used a series of rectangles which were supposed to represent the surface of the country, but mostly miss and mostly contain neighboring countries. I'm waiting for their reply.

PS. I like it when I can help and correct inaccurate data :D
