Mapzen
Mapzen, founded in 2013 and headquartered in New York City, was an open source mapping platform company focused on the core components of geo platforms, including search (geocoding), rendering ( vector tiles), navigation/ routing, and data. Mapzen's components are used by OpenStreetMap, CartoDB, and Remix, amongst others. The components, hosted on GitHub, are written in JavaScript, Ruby, Java, and Python. Mapzen's CEO, Randy Meech, was previously SVP of engineering for MapQuest. Mapzen was supported by Samsung Research America and was known to have hired mapping specialists from Apple. Mapzen shut down operations in late January, 2018. On the 28th of January 2019 The Linux Foundation announced Mapzen would become a Linux Foundation Project. Projects Mapzen's hosted products were powered by open-source components, including: Pelias- a geocoder/search engine Tangram- a set of cross-platform 3D map rendering libraries Tilezen- vector map tiles based on OpenStreetMap data V ...

GTFS
GTFS, which stands for General Transit Feed Specification or (originally) Google Transit Feed Specification, defines a common format for public transportation schedules and associated geographic information. GTFS contains only static or scheduled information about public transport services, and is sometimes known as GTFS Static to distinguish it from the GTFS Realtime extension, which defines how information on the realtime status of services can be shared. History What was to become GTFS started out as a side project of Google employee Chris Harrelson in 2005, who “monkeyed around with ways to incorporate transit data into Google Maps when he heard from Tim and Bibiana McHugh, married IT managers at TriMet, the transit agency for Portland, Oregon”. McHugh is cited with being frustrated about finding transit directions in unfamiliar cities, while popular mapping services were already offering easy-to-use driving directions at the time. Bibiana and Tim McHugh eventually go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenStreetMap
OpenStreetMap (OSM) is a free, open geographic database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial imagery and also import from other freely licensed geodata sources. OpenStreetMap is freely licensed under the Open Database License and as a result commonly used to make electronic maps, inform turn-by-turn navigation, assist in humanitarian aid and data visualisation. OpenStreetMap uses its own topology to store geographical features which can then be exported into other GIS file formats. The OpenStreetMap website itself is an online map, geodata search engine and editor. In 2004, OpenStreetMap was created by Steve Coast in response to the Ordnance Survey, the United Kingdom's national mapping agency, failing to release its data to the public and under free licences. Initially, maps were created only via GPS traces, but it was quickly populated by importing public domain geographi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java (programming Language)
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers ''write once, run anywhere'' ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. , Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers. Java was originally develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gazetteer
A gazetteer is a geographical index or directory used in conjunction with a map or atlas.Aurousseau, 61. It typically contains information concerning the geographical makeup, social statistics and physical features of a country, region, or continent. Content of a gazetteer can include a subject's location, dimensions of peaks and waterways, population, gross domestic product and literacy rate. This information is generally divided into topics with entries listed in alphabetical order. Ancient Greek gazetteers are known to have existed since the Hellenistic era. The first known Chinese gazetteer was released by the first century, and with the age of print media in China by the ninth century, the Chinese gentry became invested in producing gazetteers for their local areas as a source of information as well as local pride. The geographer Stephanus of Byzantium wrote a geographical dictionary (which currently has missing parts) in the sixth century which influenced later European ...

Routing Engine
Routing is the process of selecting a path for traffic in a network or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. In packet switching networks, routing is the higher-level decision making that directs network packets from their source toward their destination through intermediate network nodes by specific packet forwarding mechanisms. Packet forwarding is the transit of network packets from one network interface to another. Intermediate nodes are typically network hardware devices such as routers, gateways, firewalls, or switches. General-purpose computers also forward packets and perform routing, although they have no specially optimized hardware for the task. The routing process usually directs forwarding on the basis of routing tables. Routing tables maintain a record of the routes ...

Geocoder
Address geocoding, or simply geocoding, is the process of taking a text-based description of a location, such as an address or the name of a place, and returning geographic coordinates, frequently latitude/longitude pair, to identify a location on the Earth's surface. Reverse geocoding, on the other hand, converts geographic coordinates to a description of a location, usually the name of a place or an addressable location. Geocoding relies on a computer representation of address points, the street / road network, together with postal and administrative boundaries. * Geocode (''verb''): provide geographical coordinates corresponding to (a location). * Geocode (''noun''): is a code that represents a geographic entity (location or object).Sometimes the term can be used in a broader sense: the characterization of a neighborhood, locality, etc., according to such demographic features as ethnic composition or the average income or educational level of its inhabitants, especially a ...

Apple Maps
Apple Maps is a web mapping service developed by Apple Inc. The default map system of iOS, iPadOS, macOS, and watchOS, it provides directions and estimated times of arrival for driving, walking, cycling, and public transportation navigation. A "Flyover" mode shows certain densely populated urban centers and other places of interest in a 3D landscape composed of models of buildings and structures. First released in 2012, Apple Maps replaced Google Maps as the default map system on Apple devices. At launch, it drew criticism from users and reviewers for incorrect directions, sparse data about public transportation, and various other bugs and errors. Apple has since further developed the software addressing criticisms. Exclusive to Apple devices, it can be accessed on non-Apple devices in map-related search results on DuckDuckGo. History Initial release Apple revealed that the application would replace Google Maps as the default web mapping service for iOS. Apple a ...

MapQuest
MapQuest (stylized as mapquest) is an American free online web mapping service. It was launched in 1996 as the first commercial web mapping service. MapQuest vies for market share with competitors such as Google Maps and Here. History MapQuest's origins date to 1967 with the founding of Cartographic Services, a division of R.R. Donnelley & Sons in Chicago, Illinois, which moved to Lancaster, Pennsylvania, in 1969. In the mid-1980s, R.R. Donnelley & Sons began generating maps and routes for customers, with cooperation by Barry Glick, a University at Buffalo Ph.D. In 1994 it was spun off as GeoSystems Global Corporation. Much of the code was adapted for use on the Internet to create the MapQuest web service in 1996. MapQuest's original services were mapping (referred to as "Interactive Atlas") and driving directions (called "TripQuest"). Sensing the emerging demand for spatial applications on the Internet, and with crippling network latency in Lancaster, the executive team of Barr ...
