I am preparing for the upcoming photo workshop in winter’s Scotland now. Because I recently switch from Nokia N900 to Samsung Galaxy S Duos, I also wanted to update my navigation toolset. I installed popular Locus application on my handset and tried to use it with up-to-date vector Openstreetmap maps.I supposed it would be easy, however following procedures available in tools documentation, several forums and various web articles lead to many errors, mainly in the configuration, all of those must be solved before starting conversion. The following procedure consists, as I hope, from error-proof steps :o) osmosis -v –read-pbf czech_republic.osm.pbf –buffer –mapfile-writer file=czech_republic.osm.map bbox=48.542920,12.084770,51.064260,18.863210 type=hd osmosis -v –read-xml czech_republic.osm –buffer –mapfile-writer file=czech_republic.osm.map bbox=48.540841,12.085860,51.054381,18.862533 type=hd I’m an architect and I’m interested in the GIS field so I did some studies about it and my information about programming isn’t good enough to understand some points in this article what do you exactly mean by step 5 is that done through the cmd of my operating system and is this syntax is what should be written or what? The whole step 5 is about modification of batch file osmosis.bat located in /bin subfolder. You can use any text editor to do it, even simple Notepad. Source.
