A JavaScript library for visualizing 3D OSM building data on interactive maps
The whole library consists of client JavaScript files, a server side PHP script and a MySQL database. Everything should be handled as alpha state. All components are likely to change extensively.
Bottleneck is data availability. I can't process and host a whole OSM planet file. Actually I'm looking for a partner to provide a data service to you.
-
You will need MySQL as data storage. Version 5.0.16 or better has the required Spatial Extensions enabled. Everything can be done in different Geo enabled databases too. For now we just go MySQL.
-
You will need to import OSM building data from /server/buildings.sql.zip. Either upload this directly in PhpMyAdmin or unpack and import as you like.
-
Make sure PHP is running and create a /server/config.php file for your MySQL credentials. Or just adapt and rename /server/config.sample.php for your needs.
I assume, Leaflet is already integrated in your html page. If not, head over to its documentation.
Then in header section, add:
<head>
:
:
<script src="dist/buildings.js"></script>
</head>
after Leaflet initialization add:
var map = new L.Map('map');
:
:
// you may stay with any maptiles you are already using. these are just my favourites.
// remember to obtain an API key from <a href="http://mapbox.com">MapBox</a>.
// please keep the attribution part for proper copyright notice.
var mapboxTiles = new L.TileLayer(
"http://{s}.tiles.mapbox.com/v3/mapbox.mapbox-streets/{z}/{x}/{y}.png",
{

}
);
// there is just data for Berlin, Germany at the moment, lets start there
map.setView(new L.LatLng(52.52111, 13.40988), 17).addLayer(mapboxTiles);
// this applies the functionality to Leaflet
Buildings.setMap("leaflet", map);
// this finally starts loading data from your PHP/MySQL combo
// you will need to have this on the same server, otherwise there are cross origin issues
Buildings.load("server/?w={w}&n={n}&e={e}&s={s}&z={z}", {
strokeRoofs: false,
wallColor: "rgb(190,170,150)",
roofColor: "rgb(230,220,210)",
strokeColor: "rgb(145,140,135)"
});
done.
