infras: http://svevang.github.io/infras/

The goal of Infras (short for Infrastructura) is to explore the industrial systems in Puerto Rico.

Puerto Rico is an island with incredible bio-diversity and natural beauty. It is also dependent on energy production and large scale industrial systems. Infras is a map of those systems.

Quickstart

Make sure you have deps installed:

Osmosis (java): brew install osmosis
Postgresql and PostGIS

then, freshen up the git sub modules:

$ git submodule init && git submodule update

Lastly, extract and create the DB:

$ cd lib && ./create_puerto_rico_db.sh

At this point there should be a postgis enabled database. Next, build a copy of OSM-Bright:

$ cd lib && make osm-bright

Now you can fire up your copy of TileMill to start generating tiles.

Background

Slippy Map

I wanted to keep the underlying map as general as possible, so I generated the tiles for this map using TileMill. MapBox is no longet maintaining TileMill as an OSS project and has given the reins back to the open mapping community. However, the quality of the project is still very high and I was quickly able to set up a system to

Extract Open Street Map data of Puerto Rico
Load that data into a PostGis enabled database
Configure an instance of the OSM-Bright TileMill project to use that data

Next, export mbtiles for Puerto Rico using TileMill. Mbtiles are a special format that can be converted into a more traditional folder structure using the excellent mb-util tool.

The result can be seen over in svevang/puerto-rico-map-tiles

GIS Data

The GIS data is from the Gobierno de Puerto Rico. I downloaded a shape file and converted it to geojson. Something like:

ogr2ogr -f GeoJSON -t_srs crs:84 <output.json> <input.shp>

Pixel Art

This is my first attempt at pixel art!
