# Hurricane Sandy

Visualizing Hurricane Sandy with NHC data.

- [Blog post](http://mapbox.com/blog/mapping-sandy)

This repository contains two demos for working with NHC data:

- A tile maps using TileMill (View demo: [http://mapbox.com/sandy/tiles](http://mapbox.com/sandy/tiles))
- A vector map using ogr2ogr and Polymap (View demo: [http://mapbox.com/sandy/vector](http://mapbox.com/sandy/vector))

## Tile Map

- Use [TileMill](http://mapbox.com/tilemill/) to render NHC shapefiles
- Use [mapbox.js](http://mapbox.com/mapbox.js/api/v0.6.6/) to display tile layer together with [MapBox Streets](https://tiles.mapbox.com/mapbox/map/mapbox-streets).
- TileMill project in `tiles/tilemill/sandy`
- See map embedding with mapbox.js in `tiles/site.js`

## Vector Map

- Convert shapefiles to geojson with [GDAL's ogr2ogr](http://www.gdal.org/)
- Use Polymaps to render geojson on top of [MapBox Streets](https://tiles.mapbox.com/mapbox/map/mapbox-streets).
- See ogr2ogr conversion in `vector/data/shp2geojson`
- See polymaps usage in `vector/site.js`

## Data

Weather data is from the National Hurricane Center (NHC). Map data is from [OpenStreetMap](http://www.openstreetmap.org/).
