GeoAstro API: GeoAstroApi is an API for retrieving geographical and astronomical info. With the API users can get info such as the sunrise and sunset for a location, moonrise and moonset for a location, moon phases for a date, the fraction of the moon that is illuminated and also convert Julian/Gregorian dates. The API uses HTTP calls and responses are formatted in JSON.
GeoCommunicator API: This service from the U.S. Bureau of Land Management provides mapping services to support ArcIMS image applications, ArcGIS applications, and other local GIS functions. Separate data services provide lookup functions for public land descriptions, surveys, and range allotments, as well as BLM administrative areas and specific sites it manages (e.g., abandoned mines, campgrounds, buildings, etc.).
Methods support mapping rangelands, allotments and pastures, administrative boundaries, and facilities. Data methods retrieve a land description based on the location or determine a location based on the land description.
OremGeocoder API: The OremGeocoder API allows GIS applications to plot Orem, UT addresses even when street names are placed before house numbers, streets have more than one name, or address coordinates don't match any streets at all. A closely related API that consumes this one informs the user which polygon on the map contains a given address.
GovHG Data.One API: Data.One on Hong Kong's government website, GovHK, provides public sector information, currently for geo-referenced public facility data and real-time traffic data. The traffic data, in the form of traffic speed maps, journey time indicators, and special traffic news, is also available via an API returning responses in XML.
Open311 API: Note: This is an API standard used by many API providers. For all compatible APIs listed on ProgrammableWeb, use the [[http://www.programmableweb.com/apitag/open311 open311 tag]].
Open311 allows developers to create third-party apps for citizens to report neighborhood issues from, potholes to graffiti and more, to a city's 311 system.
Open311 provides an Inquiry API to retrieve information such as services, facilities, and a 311 event update. The GeoReport API is the reporting API used to submit issues to the 311 service. These APIs are RESTful.
Nos Données (Our Data) API: NosDonnées.fr (Our Data) opens government data to the public, encouraging citizens to find and reuse public data. Available datasets include: geographic data; health; export and imports; energy statistics; election results; tax rates; maps of amenities; and more.
