Nainstalovat mapnik
===================

+ apt-get install imagemagick

REnder
======

http://wiki.openstreetmap.org/wiki/Mapnik#Rendering_with_Mapnik


Můj generate_tiles.py pro čechy
    minZoom = 8
    maxZoom = 16
    bbox = (14.05,49.849, 14.815,50.325)
    render_tiles(bbox, mapfile, tile_dir, minZoom, maxZoom , "Praha")

 

WMS Server
==========
Zajímave: http://wiki.openstreetmap.org/wiki/WMS


Mapnik ho už obsahuje, stačí následovat:
http://code.google.com/p/mapnik-utils/wiki/WmsInstallGuide
a http://trac.mapnik.org/browser/trunk/docs/ogcserver/readme.txt


Má to dost závislostí:
* Stáhnout jonpy + python setup.py install
* apt-get install python-imaging python-lxml

>"importError: No module named ogcserver.cgiserver"
Spouštěl jsem "python" ve složce, kde byl i mapnik.py, takže to dalo přednost tomuto souboru před modulem.
