SVG Tiles in Leaflet

Quickstart

git clone git@github.com:springmeyer/svg-tiles.git
cd svg-tiles
npm install
./server.js & open http://localhost:4000

Details

This demo shows the loading of a few pre-styled tiles in SVGZ format at z12 into Leaflet. This works in Chrome and Safari (at least) because the SVGZ tiles can be treated like images and loaded into a <img> element.

See the code comments in index.html for customizations to the demo like loading tiles into <svg> elements instead of <img> by @jfirebaugh and using overzooming via @nrenner.

See the code comments in server.js for enabling code to optimized and re-style the SVG before providing to the browser client via @ZJONSSON.

To view the underlying svg uncompressed you can do (with the server running - see below):

wget http://localhost:4000/tiles/12/1171/1566.svgz
mv 1566.svgz 1566.svg.gz
gzip -d 1566.svg.gz

Then open 1566.svg in your editor.

The tiles are styled by Mapnik using Mapnik's Cairo backend.

Depends

• Node.js v0.8.x or v0.10.x

Setup

After installing Node.js inside this directory run:

npm install

Which will install express and expat.

Using

Start the server:

node server.js

Then in a web browser go to http://localhost:4000 and you should be greeted with a few tiles of Washington DC at z12. Zooming or panning will not work since this demo only provides the tiles in the extent of the initial viewport.
