ovrdc-tileserver
==============

THIS PROJECT IS NO LONGER ACTIVE. BELOW IS THE FINAL STATS SCREENSHOT.
--------

This is fork of Tobin Bradley's mbtiles-server which is a fork of Christopher Helm's [mbtiles-server](https://github.com/chelm/mbtiles-server) - see below for Tobin Bradley's description. This server adds a tile preview page and server stats.

These results using ```loadtest``` are from the second smallest Digital Ocean droplet requesting one pbf file from an mbtiles file, proxied with NGINX. An average map takes around 30-70 requests to render. Is this good? Seems like it, especially for smaller municipal government apps, which is our domain.

This fork also uses some code from tilehut, another great implementation of an mbtiles server.

Add mbtiles to the ```tiles``` folder then start the server. All mbtiles will be served. It works with raster and vector tiles.

``` bash
npm install
node tileserver.js
```

Requests look like this:
