[ gpsdrive ] GPSdrive Digest, Vol 7, Issue 8

Sun Aug 12 22:39:55 AKDT 2007

Hi,

Thanks! I tried Documentation/install-mapnik-osm.txt. It is working:-) Although, even the latest (http://gpsdrive.de/gpsdrive.tar/gpsdrive-2.10svn15254082.tar.gz) tar does not contains install-mapnik-osm.txt. It is only appears in svn repository at http://svn.gpsdrive.cc/gpsdrive/trunk/

I realised that this method using rendering map tiles in one step by running gpsdrive_mapnik_gentiles.pl. Is it planned to render the tiles on-the-fly later?

Hi,

I'm using gpsdrive-2.10svn15113909, and I would like to try vector map.

I followed instruction in README.OpenStreetMap-Vektordata:

geoinfo.pl --db-user=root --db-password='mypwd' --create-db --fill-defaults

finishes successfully, but when I execute

geoinfo.pl --db-user=root --db-password='mypwd' --osm

I got the following:

Import OSM Data(world)
Delete old 'OSM node' Data
Delete old 'OSM segment' Data
Delete old 'OSM way' Data
Import OSM Data ''
Download planet-xxxxxx.osm
Mirror /home/tszabo/osm/planet/planet-070801.osm complete

than geoinfo stucks. It quicky eats my 1GB RAM that slowly occupy ~700MB 
of swap memory (this case was after ~14 hours). During CPU runs at 100% 
(until eats all RAM, than HDD using goes up to 100%). However df -h does 
not show any disk space reduction and no data imported to 'streets'.

I also tried:

geoinfo.pl --db-user=root --db-password='mypwd' 
--osm=download:muenchen_part --show-traffic

result:

Import OSM Data(world)
Delete old 'OSM node' Data
Delete old 'OSM segment' Data
Delete old 'OSM way' Data
Import OSM Data 'download:muenchen_part'
Download OSM Data
Download OSM Area muenchen_part (11.5,48,     11.6,48.1)
Get 11.5,48                        Got 11.5,48             345 Bytes
/home/tszabo/.gpsdrive/MIRROR/osm/Streets_osm_48.00,011.50,48.10,011.60.osm: 
345 Bytes

Download and import of OSM Data FINISHED

however Streets_osm_48.00,011.50,48.10,011.60.osm contains:

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
          "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
  <head>
   <title>403 - Forbidden</title>
  </head>
  <body>
   <h1>403 - Forbidden</h1>
  </body>
</html>

I think API 0.3 is not usable, so I modified to 0.4:

my $osm_base_url="http://www.openstreetmap.org/api/0.4/map?bbox=";

the result is a lot of "cannot determine streets_type_id for way 
(xxxxxxxx)".

In case of WDB the case is better, data is dowloaded and inserted into 
database, however in gpsdrive nothing displayed, although it can connect 
to geoinfo db as gast with pwd=gast.

Have anybody any idea what I make wrong?

Thx,

Ups, ....

this part of the README is a little bit outdated.
This Programm still exists and has it's use, but only will be used for the 
point of interrests to insert into the database.
The problem is that this option (--osm) only works if you have at least 4GB of 
RAM or if you specify the area option. So for example the call would be:

geoinfo.pl --db-user=root --db-password='mypwd' --osm --area=germany

But on the other Hand inserting wdb should work with less memory. But after 
this the vectordata is only in the mysql database which is almost not or 
really purely rendered. So this probably doesn't make too much sense to use.
I'll probably rip this part out of gpsdrive soon. This was kind of a proof of 
concept to work with real Vectordata.

But if you only like to have good Vectormaps, please follow the instructions 
for installing mapnik for GpsDrive.
Documentation/install-mapnik-osm.txt

There are already some basic debian packages for this purpose:
openstreetmap-mapnik-data
openstreetmap-mapnik-world-boundaries
