JSONP API for Portland, OR civic data

PDXAPI is a GeoCouch instance populated with data from the City of Portland, Oregon through CivicApps. Out of the box CouchDB provides a RESTy JSON API to all of the data.

• Create an easily consumable data resource for developers interested in utilizing Portland civic data
• Modify and build upon the city’s publicly released data by allowing users to edit and contribute data, and even start whole new datasets
• Create automated processes for synchronizing with the original data sources (City of Portland, Metro, TriMet)
• Create tools and examples for developers to use as a jumping off point for creating ‘civic apps’
• Wiki-style revision history and conflict management/dispute resolution when users contribute to datasets

See pdxapi.com for more information and example usage.

The basic usage is to ask PDXAPI for all objects in a database contained within a particular bounding box. You can see an example of this on the PDXAPI.com homepage. You will receive a GeoJSON feature collection that contains any matching objects. Each object consists of some location data and an ID that you can use to look up metadata for the object by asking http://pdxapi.com/dataset/id

If you are interested in working with a local instance of PDXAPI, the included pdxapi_installer file demonstrates how to convert download Shapefiles from CivicApps and load them into GeoCouch. The old_scripts directory contains a bunch of geospatial related utilities developed for PDXAPI that are no longer in use, but may be useful as a reference.

• shp2geocouch is a rubygem that converts Shapefiles into GeoCouch databases.
• Food Cart Pages is an example web application that uses PDXAPI as it’s data store.
• Food Cart Finder Mobile is an example mobile application (native iPhone and Android) that uses PDXAPI as it’s data store.
