CitySDK-ArcGIS is a simple JavaScript library for connecting to the GeoServices API powered by ArcGIS. These services are available from local cities and governments around the world. CitySDK is developed by the US Census for web developers to quickly connect to the rich sets of national data that provide context for local communities.
CitySDK provides easy access to the full suite of Census API and data. Through a simple JavaScript interface developers can request population, income, commutes and more by tract, block, county, or state.
GeoServices are an open, RESTful API for accessing data. The API provides direct access to authoritative data with SQL-like query, location and time filtering, statistical aggregation, and analysis processing.
They power over 23,000 government agencies, all with a common API - whether it's Schools in DC or Health in Colorado - discover local data from ArcGIS Open Data community and US Data.gov.
Governments are making their data available for innovative citizens to create new insights for business opportunities, local community and government efficiency. Combining national Census data with local city data provides everyone with the opportunity to discover and share new ideas.
