###Download and install

easy_install tilestache

###Usage

Background:

TileStache URLs are based on a simplified TMS scheme:

/{layer name}/{zoom}/{column}/{row}.{extension}

To preview tiles:

Start the mini server and then view using the preview.html hook. Inside your project directory you'll setup a cgi and load the page in your web browser. Append

/layername/preview.html

Note, the hash bit after the .html tracks the zoom, lat and long so you can bookmark share the current view.

#12/37.8110/-122.2660

For example, let's find out the intranet IP of the machine:

ifconfig

gunicorn -b 192.168.1.5:4132 "TileStache:WSGITileServer('tilestache.cfg')"

Note: Choose a port number that is on the lower side. Ones in the 90000 range don't work.

The in your web browser:

http://192.168.1.5:4132/{layername}/preview.html

To cache tiles:

Tilestache-seed.py (doc) reads a configuration file, you specify which layer and a bounding box with zooms. Sometimes permissions can be an issue so these are run as a special user called www-data.

sudo -u www-data tilestache-seed.py -c tilestache.cfg -l hybrid -b -50 3 53.5 8 -x 7 8 9 10

sudo -u www-data tilestache-seed.py -c tilestache.cfg -l hybrid -b -52.27 4.71 52.47 5.06 -x 11 12
