Seattle Atlas

Provides convenient method to download Seattle related shapefiles and convert some of them to TopoJSON format.

Inspired by Bostock's world-atlas.

Idea copied from and based on Justin Palmer's portland-atlas.

Prerequisites

Before you can run make, you’ll need to install Node and ogr2ogr and some other prereqs. If you are on Mac OS X, and using Homebrew then just run:

brew install node
brew install gdal
brew install cairo

And then, from this repository’s root directory, install the dependencies:

npm install

If you run into problems with installing node-canvas, you might need to setup your PKG_CONFIG_PATH like so:

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/opt/X11/lib/pkgconfig

This comes from the node-canvas OSX install page.

Make Targets

...	...	...
Neighborhoods	Building Footprints	Streets
Parks	Zoning	Trees
Shorelines	Streams	Addresses
Census Tracts	School Districts	Block Groups
Beach Access	Geo Names	Tribal Lands

All Make Targets can be run using make. Example:

make shp/buildings.shp

Shapefiles

shp/osm.shp

Shapefiles from Metro Extracts.

shp/buildings.shp

2009 building footprints from Data Portal

shp/neighborhoods.shp

Neighborhood outlines from Data Portal

shp/streets.shp

Street Network data from Data Portal

shp/parks.shp

Parks from Data Portal

shp/zoning.shp

shp/shorelines.shp

Shoreline data from Data Portal

shp/streams.shp

shp/tracts.shp

shp/beach-access.shp

Beach Access Sites from WA Ecology Dept

shp/geo-names.shp

geoJSON

GeoJSON conversion should work for any of the above shapefiles. The make command uses geo as the sub-directory. So, for example, to make a geoJSON file for neighborhoods, it would look something like:

geo/neighborhoods.json

Note the geo prefix and the .json extension.

There are also a few geoJSON specific files:

geo/starbucks.json - location of all starbucks

TopoJSON

topo/neighborhoods.json

topo/parks.json
