Why not ask your question on the new OpenStreetMap Community Forum?


Like the following manual https://wiki.openstreetmap.org/wiki/DE:Bigmap I downloaded a mkmap.pl file. With perl mkmap.pl > mymap.png I tried to create a png file.

During the download sometimes appears: http://tile.openstreetmap.org/11/1097/729.png... 500 Status read failed: Eine vorhandene Verbindung wurde vom Remotehost geschlossen.

Sometrimes appears: http://tile.openstreetmap.org/11/1095/745.png... 500 Can't connect to tile.openstreetmap.org:80 (Invalid argument)

Mostly appears: http://tile.openstreetmap.org/11/1096/748.png... 200 OK

After about 1 hour appears: <html><head> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="refresh" content="0;url=/ui/dboard"> </head></html> not found: Invalid argument at C:/Perl64/lib/GD/Image.pm line 64.

At the end, normally the png-file is empty. Once I had a png File (93MB) but with many white squares.

What do I wrong?

Thanks and best regards!

my mkmap.pl file contains:
