Just posted this on the NZ Open GPS Web site about how to download and have offline the NZ Open GPS Mapset onto an Android phone for full turn by turn driving.

Looks good but I can't seem to run the python script. A quick peek at the script seems to expect "input.mp" as input file name? I renamed the downloaded Canterbury.mp to input.mp. That didn't seem to help either. I keep getting this error:

File "mp2osm_linz_jr_pl.py", line 268
print 'ptang missing 0x%x poi:%s line:%s poly:%s sufi:%s' % (typecode, poi, polyline, polygon, sufi)
^
SyntaxError: invalid syntax

Yeah I hit a hurdle too. Did the same as you, renamed files to input.mp which seemed to work, but got an error on the next step.

What do you mean by "...seemed to work"? I get the exact same error before and after I renamed the input file.

That free app isn't worth the hassle, its bloated and slow, I deleted it after trying it for a few days.

I would recommend http://www.appbrain.com/app/navdroyd/com.osa.android.navdroyd for an offline only solution. NavDroyd is cheap for only $9.25 NZ and will work in every single country in the world using OSM. It provides turn-by-turn guidance and regular map updates too. The guidance is good, it even says street names just like Google Navi does.

The biggest pitfall is that OSM maps are lacking sometimes. But I have used them around Auckland and have been just fine for my needs. At least map updates are regular.

NavDroyd map data is much smaller than that OSMAnd thing, I think NZ was around 9MB only. And it is from the same source OSM so their compression/vector format must be superior.

You probably need a newer version of Python, I used 2.7 and it worked fine.

If you're logged into the NZ Open GIS site you can download my modified version of the python, it's an attachment at the bottom of the post...

Ahh that's why I am not using OSM Data, I am using the NZ Open GIS data. Which does give you turn by turn based off the solid efforts of the NZ folks who have taken the LINZ data and made it great. I havn't found OsmAnd bloated or slow, it renders on my wifes flipout in a few seconds and works completely offline. We'll be taking it for a good test when I go for a large drive in a few weeks. But so far around town it's been great... With the NZ Open GIS data rather than OSM which is still somewhat lacking in NZ.

I was already using the script from the NZ Open GIS site. Interestingly I needed an older version of Python. I was using 3.1.2 when it failed - tried it with 2.7 and it worked fine.

I said it seemed to work because it gave me an output file, but I wasn't actually sure if it was complete. Thought maybe it was why I couldn't get past the next step without errors.

If you run it through Osmosis then you will know if it's a valid OSM XML File or not.

4.1) (Optional) Use Osmosis to convert from a OSM XML file into a OSM PBF Binary file. using "osmosis --rx input.osm --write-bin input.osm.pbf omitmetadata=true". This also checks it's a valid XML file you're working with.

But if the Python exits successfully and returns a sane set of totals... Then it should have worked fine.

Oh fair enough, i thought NZ open maps was same as OSM. I have found OSM pretty sufficient, only thing it lacked was like this semi-private road when I went down to coromandel during christmas, otherwise it has been find around auckland and efficient and yes OSMAnd works it is pretty slow when compared to NavDroyd atleast for me. Also I didn't feel like going through that hassle of setting it all up. But I will give it another go sometime.
