Re: [talk-au] Making a Laptop GPS

[John Kitchener]

Hi Richard,

If you're up to XP; why not use Garmin's nRoute plus OSM. 

Perfect auto-routing moving map.

Garmin no longer support or provide downloads for nRoute so have a look at
this GPSAustralia post for details:

Re: [talk-au] Mini Roundabouts.

[John Kitchener]

For me, the single most relevant issue is how does a 'mini roundabout'
display with Garmin turn by voice routing?

 

>From memory (I haven't played with it recently), a 'mini roundabout' works
in Garmin as a standard cross street. This is quite confusing when presented
with a real round-about.

 

Mini roundabouts are unacceptable . in my opinion.

[talk-au] re Coastline rendering in Garmins Mapsource

[John Kitchener]

Seems Openmtbmap has recently got 'sea polygons' organized. :)

Here is a Mapsource Noosa view. It's not 100% for the entire coastline, but
it's pretty damn good.

[talk-au] re Coastline rendering in Garmins Mapsource

Matt wrote:

Coastlines (and the "inverse islands" issues) have been ongoing for ages for
the Mkgmap produced Garmin files. There's a --generate-sea switch for Mkgmap
that sometimes works fine, other times, not so good. It's hit and miss
enough that I've never enabled it for the maps I generate.

Problem seems to come from a few different things - non-closed coastline
polygons, coastline direction changes, points where rivers join
sea/coastline etc.

There's a lot of chat on the mkg-map dev list over the last 6 months or so
regarding this.

Thanks Matt. Without 'sea polygons' it'll remain a complete mess for Garmin
displays. We need OSM to work in the 'real world' to accelerate uptake.

Hopefully the --generate-sea- switch comes good in Mkgmap. Until then .

PS The OsmAustralia downloads appear stuck at the 26/1 at 22b. Happy
Australia Day. :)

[talk-au] Coastline rendering in Garmins Mapsource

[John Kitchener]

 Hi,

I guess this is an old issue; but there appears to be a problem when
displaying OSM coastlines in Mapsource. Have a squiz at these three images
of Noosa (QLD):

# Mapsource - good old Shonky looks - good
http://img651.imageshack.us/img651/9489/clipboard02j.jpg
# OSM   -
on the Web is good - http://img10.imageshack.us/img10/4807/clipboard03ph.jpg
# Mapsource - OSM is rubbish! -
http://img10.imageshack.us/img10/8682/clipboard04tf.jpg

Rivers get to be blue but the sea is invariably white with a demarcation
line somewhere at the mouth or up river. Tagging looks fine. The Mapsource
(and I presume GPS - I don't own a mapping Garmin) display problem could be
associated with a dis-continuous coastline polygon (the 'Coastline Error
Checker' shows a few current issues for Aus). I guess this is an ongoing
issue, as folk fiddle? 

However I also suspect there is some deeper issue, as NZ's coastline appears
to be a closed polygon; with the same problem. If anyone has info or
solutions for this problem, please advise.

 

In the meantime don't go boating with OSM aboard. J

[talk-au] Viewing OSM Maps in mapsource

[John Kitchener]

As many of you would know, OSM Australia
http://www.osmaustralia.org/downloads.php provides a fantastic resource of
compiled OSM Garmin maps in .img format.

 

Recently 'tdb' and 'overview' file information has been included in the
nightly downloads. This has provided the means for a simple automated method
of loading the maps to Garmin's Mapsource for viewing, test of routing,
feature display etc.

 

The procedure (with credits) is found here
http://www.gpsaustralia.net/forums/showpost.php?p=57552

&postcount=216

 

Matt (OSM Australia), has advised that he will include the Mapsource
procedure in the OSM Australia 'How To' section in due course.

 

Regards

[talk-au] Routable maps

[John Kitchener]

An easy routable OSM source is 

 

http://garmin.na1400.info/routable.php

 

Once you've selected your tile(s) you get emailed a link where to download
the file from with a choice of installation possibilities - VERY COOL. The
map tiles are far from perfect and update is monthly (I think).
