Mouseover streets in this D3.js-driven visualization that allows users to visualize the citywide extent of a given street. The City of Philadelphia Streets Department maintains and distributes geospatial data representing and describing the city's street network. The data along with more information is availabe at Open Data Philly. Street location and name data is stored in a CartoDB table. A merge by attribute operation, street name in this case, achieved improvements over the previous file size that approached 3MB.

Download size can be further reduced by using PostGIS functions ST_Simplify or ST_SimplifyPreserveTopology. Without loss of det

The map is created using Leaflet. The hexbin layer is a custom Leaflet layer which uses d3js to generate a svg hexbin overlay. The source for the custom leaflet layer is viewable here.

##What are we trying to do?

The City of Philadelphia (specifically, the Managing Director’s Office) is looking to engage with a local developer, entrepreneur or software firm to build a mobile application we're calling myPhillyRising.

The purpose of this application is to complement the work being done by the PhillyRising Collaborative in specific neighborhoods in the City of Philadelphia. It is meant to be offered for free use by residents in neighborhoods that are the focus of PhillyRising activities.

##Why are we trying to do this?

PhillyRising, an initiative of the City's Managing Director's office, is built on the idea of collaboration – government collaborating with citizens and community leaders to improve the quality of life in city neighborhoods. PhillyRising targets neighborhoods throughout Philadelphia that are plagued by chronic crime and quality of life concerns, and establishes partnerships with community members to help address these issues.
