Make your first map

Hi,
I am following this article step by step
But when I try this command I get this error
user@PC1:~/mapnik$ source set-mapnik-env
bash: #!/bin/sh: No such file or directory,
please help

and also one more question what do u mean by:
"
Do not omit the leading "periods" on lines two and three.
source set-mapnik-env
./customize-mapnik-map >$MAPNIK_MAP_FILE
./z0_generate_tiles.py
"

thanks and great tutorial

I use Ubuntu 8.10, , now i updated it to interpid ubuntu...

user@PC1:~$ ln -s /bin/sh /bin/bash
ln: creating symbolic link `/bin/bash': File exists

I tried this:
userr@PC1:~/mapnik$ source set-mapnik-env
bash: #!/bin/bash: No such file or directory
userr@PC1:~/mapnik$ sudo source set-mapnik-env
[sudo] password for user:
sudo: source: command not found

what can done to solve it?

thanks

I have been following your tutorials carefully, and except for a few problems (of my own) and one I can't still figure out (pink tiles on Mac G5 Circa 2006) everything has worked well. I encourage those who are interested to follow along. Anyway I have a few more questions.
1.) At the start of this exercise we downloaded LAMP and was wondering how this fits into the grand plan. Am I missing something?
2.) I have been experimenting around with generate_tiles.py to get my tiles rendered. I am having difficulty with understanding the script, specifically toward the end. Now I understand that I should change the bounding box per my parameters. But, what are all the references to Europe and city's like Muenchen? Could you give me an example of what my generate_tiles.py script should look like if I want to render zoom levels 12-18 with a bbox = (-82.141, 41.665, -81.31, 41.116) i.e. Cleveland, Ohio. ? The approach I'd like to take is at this link: http://wiki.openstreetmap.org/wiki/Creating_your_own_tiles:
"Creating tiles using Mapnik and generate_tiles.py
This is the method used by, for example, the OSM cycle map. Its main advantage is that nothing needs to run on the webserver - it just needs a directory of image files. So, for example, you can install all the software on your home PC, and transfer the tiles to your webhost when you're finished.
* Download the planet file from planet.openstreetmap.org
* Import into a PostGIS database using osm2pgsql
* Set up mapnik and test using osm.xml and the generate_image.py
* When everything works, use generate_tiles.py to create 1000s of tiles in a special hierarchy of folders
* Copy/move tiles into your webserver's document root.
* Change the OpenLayers instance to use your own tileserver instead of the main one "

Any help you could give me along these lines would be welcomed.

Kind Regards,

Hi richard,
1. if I set the bounding box to australia in this line: bbox = (-180.0,-90.0, 180.0,90.0) to (101.1,-6.9,165.5,-45.9)
the images generated by mapnik are only for australia?
2. I have a custom images as australia maps (it's only 6 levels not like OSM ) that we paid for , do u have any idea how to use them with OSM?

level 1 to level 6:
Level 1 = 24 images
a1_1_1.gif
a1_2_1.gif
…
…
a4_6_1.gif

Level 2 = 586 images
a1_4_2.gif
…
…
a21_30_2.gif

Level 6 = 2190 images
a686_1809_6.gif
…
…
a1172_1503_6.gif

thanks

I love your tutorials.

If I want to build map for a single country from the files from cloudmade.com do I need just the country .osm file?
Can I follow your tutorial without a change or do I need to set the bounding box of that country?
How do I know the bounding box of the country?

It'll be cool to have a tutorial how to setup mod_tile in front of mapnik.

Thanks

Thanks for this great tutorial !!

I'm having a problem rendering the test map although I've successfully used this tutorial on my computer at work - both machines are running OS X 10.5.8 and the OSM stack has been setup in the same way.

The output of running the commands is shown below, it's more than 5 lines but I did build mapnik in debug mode if that's the difference. After the output about cleaning up the font faces the process appears to hang and eventually python crashes.

Any clues on how to debug this problem would be much appreciated.

Cheers
Adam

sorry for my english i'm a student
hi i'm newbie on this subject i recently follow your steps but occurred an issue maybe because i took another way (downloaded from cloudemade different source of data, is from mexico)
i did this steps

source set-mapnik-env
./customize-mapnik-map >$MAPNIK_MAP_FILE
./my_generate_image.py

but in the last one appear this problem

Traceback (most recent call last):
File "./my_generate_image.py", line 16, in
from mapnik import *
AttributeError: 'module' object has no attribute 'Geometry2d'

i change some values from my_generate_image.py file to match with the bounding box that i want

what can i do?

thanks

Could not load map file '/home/my_username/svn.openstreetmap.org/applications/rendering/mapnik/osm-local.xml': File does not exist

Hi....
I ve successfully gone through all this setup process, generating tiles and then using them for my web application.....
But the problem i am facing is this while accessing the tiles in my app, everything works fine till level 0-7...but when i try to zoom in further, I get pink tiles, whereas the tiles for higher levels do exist in their corresponding folders......
definition for my OSM layer in my app is
var localLayer = new OpenLayers.Layer.OSM("My Local OSM","/${z}/${x}/${y}.png",{numZoomLevels:19});

Hi

Thanks for the great description. I managed to make it work despite some missing table
entries which were added to the database by hand.

But when I generate tiles and images the osm data (for example roads and names) do not match
the word_shape/coastlines - they are offset by several kilometers.

Has anyone seen this problem?

I use the denmark data from http://download.geofabrik.de/osm/europe/
and the shapefiles from the sources described in the walk-through.

Cheers

Morten

Hi,
Thanks for you work putting together this tutorial, it was very helpful. Are there any good how-to's on creating a www interface - i know i'm supposed to use mod_tile and openlayers but despite wasting 3 days on the subject and googling half of the entire internet i failed to find a relevant advice on this subject.

please help me
Adam

I managed to install Openstreetmap on Gentoo (status: December 2009) and I could generate some interesting tiles of Poschiavo, which is a little valley in the mountains where I live. My server is an AMD k6-700 MHZ with 600 MB of RAM, so not a real power horse but quite an old scrap iron thing. Of course, I did not import the whole planet, but only a dump of Switzerland.

I wrote down some steps that differ from the very good tutorials here, because the installation is performed on Gentoo instead of Ubuntu: of course, this is working now as for December 2009, but an emerge --sync in the future might solve some of these problematic steps (maybe someone more knowledgeable than me will read this tutorial and fix some ebuilds :-).

Step: Subversion and Java
-------------------------
These one were easy and you probably figured out faster than me:
emerge -av subversion
emerge -av sun-jdk

Step: Installing Postgresql with Postigs
----------------------------------------

osm2pgsql does not work with Postgresql 8.1 which is marked stable in Gentoo. The reason is that
Postgresql 8.1.11 does not know about the command 'DROP TABLE IF EXISTS' which is used in oms2pgsql. Defining a stored procedure that does the same and modifying the source code of osm2pgsql did not work for me.

Therefore I chose another way, which goes as follows: you should add at the end of /root/.bashrc the following alias:
alias aemerge='ACCEPT_KEYWORDS="~x86" emerge '

source /root/.bashrc will load this setting for the first time. The setting is kept after, as .bashrc is read at every login.
From now on, you can use "aemerge" to emerge unstable packages instead of "emerge".

Then, you can install an unstable Postgresql with
aemerge -av postgresql
This will install a Postgresql 8.2.14 which is fine for our purposes.

Install also Postgis:
aemerge -av postgis
Postgis-1.4.0 was then installed.

Configure the database postgis extensions not by using emerge --config as suggested at the end of emerge, but use the instructions provided in this tutorial. Remember to follow the instructions as normal user and not as superuser (a part of the inital step of setting up the database).

As noted in the previous comment, lwpostgresql.sql does not exist in postgis anymore, it was renamed in postgis.sql, you should therefore use
psql -d gis -f /usr/share/postgresql/contrib/postgis.sql

Step: Installing mapnik
-----------------------

For mapnik I had problems, it did not compile from source as described in the tutorial, it was failing when compiling the postgis plugin for linking reasons against the library libpq.la, though the library was present on the proposed path.

I did the following trick:

USE="postgresql" aemerge -av mapnik
emerged and installed a mapnik with all dependencies, which however was not able to recognize the postgis extensions on the 'gis' database.

In fact, when running ./z0_generate_tiles.py, mapnik was failing with:
"
Could not create datasource. No plugin found for type 'postgis' (encountered during parsing of layer 'leisure') when connecting to the imported database.
"
This error message is listed as comment in the next tutorial as well.

Then I did the following:
I unmerged the unstable libpq library (libpq is a library used by postgresql used as connection layer.
emerge --unmerge libpq
I unmerged mapnik without its dependencies with
emerge --unmerge mapnik

I installed the stable libpq library with:
emerge -av libpq

Then I installed mapnik from source with the following steps

mkdir src
cd src
svn co http://svn.mapnik.org/trunk/ mapnik
cd mapnik
scons/scons.py -c install
scons/scons.py PGSQL_LIBS=/usr/lib/postgresql/ PGSQL_INCLUDES=/usr/include/postgresql/
sudo scons/scons.py install PGSQL_LIBS=/usr/lib/postgresql/ PGSQL_INCLUDES=/usr/include/postgresql/
ldconfig

Therefore: postgresql is compiled against an unstable version of libpq, while mapnik needs a stable one to compile.
Of course, postgresql will survive the restart with /etc/init.d/postgresql restart :-)

Have fun with your maps!

Hello,

I've been following the tutorials very closely, I've downloaded the planet file, carved out the area of interest (in this case following your example).

I'm using the same bounding box as the tutorial for the osm carving and tile extraction (-94,38,-71.5,50).

I carved my GreatLakes.osm.gz file out of a complete planet file (planet-100106.osm) using osmosis.

This is the output from the database insertion:

z0_generate_tiles.py creates a map of the world (as expected).
When I try to render the image using: ./my_generate_image.py I get the correct area on the map (I can see the coastline data), but I'm not seeing any openstreetmap data.

I have a feeling that this may be a projection issue - when I installed postgis, I installed the /usr/share/postgresql/8.4/contrib/spatial_ref_sys.sql file. I missed the loading 900913.sql file (would this make a difference?).
I am running on Karmic.

Thanks for your assistance.

I've been scratching my head for days!

I've followed this tutorial many time successfully, but this time I'm having a strange problem I haven't seen before. The only difference in setup this time is that I'm running Debian instead of Ubuntu. I imported some osm data as usual and with no problems, but when I try to render an image I get the coastlines and I get one big park rendered from the OSM data, but none of the roads or other objects from the database. I'm at a loss because I don't understand why just one object would be rendered from the database but nothing else.

I tried again with tiles, but they won't render at all, unlike the image. The error is:

Exception in thread Thread-2:
Traceback (most recent call last):
File "/usr/lib/python2.5/threading.py", line 486, in __bootstrap_inner

File "./gotile.py", line 85, in render_tile
self.m.resize(render_size, render_size)
AttributeError: 'Map' object has no attribute 'resize'

Any advice?

Dear sir/ madam

I am student, from Stuttgart university of applied sciences. I tried to set post gis server and using osm2pgsql tool i am able to create geodatabase.
now i have problem rendering with mapnik on windows. I tried all the sources from web wikipedia, and some other blogs.
even i mailed my problem to mapnik directly.

I would appericiate if you please help me in rendering

the commands i used are following.

1. Downloaded and installed the SVN-client.
2. Exported the Mapnik stuff from the OSM subversion repository. using command prompt and command i used

svn export http://svn.openstreetmap.org/applications/rendering/mapnik

3.To generate my own XML-file with the connection to PostgreSQL / PostGIS used command prompt, navigated to the Mapnik-directory and executed the command

generate_xml.py osm.xml osm-local.xml --host localhost --user abc --dbname gis --symbols ./symbols/ --world_boundaries ./world_boundaries/ --port 5432 --password *

but here i am getting errors in command prompt

Trackback (most recent call last):
file "C:\mapnik\generate_xml.py", line 194, in
serialize(template_xml,options)
file "C:\mapnik\generate_xml.py", line 70, in serialize
mapnik.load_map(m,xml,true)
RuntimeError: c:/mapnik/worl_boundaries/builtup_area does not exist (encountered during parsing of layer 'builtup')

I am not getting how to remove these errors, than how to render with mapnik to visulize these tiles.

Look forward to your response.
