The gravitational field of the earth is non-uniform. The geoid is the shape the
ocean surface would take if only gravity and the rotation of the Earth
were considered. The geoid is the surface that defines zero elevation.
The geoid height is the difference between an ideal reference ellipsoid and the geoid.
The gravity anomaly is the difference between the acceleration due to gravity on the Earth's surface and the value calculated assuming the reference ellipsoid.
The official Earth Gravitational Model EGM2008 was developed and released to the public by the National Geospatial-Intelligence Agency (NGA).
Our EGM2008 API provides on-demand access to the EGM2008 model, as implemented by the open-source GeographicLib Gravity library.

This is the documentation for the Weatherbit Weather API. The base URL for the API is http://api.weatherbit.io/v2.0/ or https://api.weatherbit.io/v2.0/. Below is the Swagger UI documentation for the API. All API requests require the key parameter. An Example for a 5 day forecast for London, UK would be http://api.weatherbit.io/v2.0/forecast/3hourly?city=London&country=UK. See our Weather API description page for additional documentation.

The Maps API web services suite offers the following APIs:
Raster
The Maps Raster API renders map data that is divided into gridded sections called tiles. Tiles are square images (png or jpg format) in various sizes which are available at 19 different zoom levels, ranging from 0 to 20. For zoom level 0, the entire earth is displayed on one single tile, while at zoom level 20, the world is divided into 2 40 tiles.
Vector
Similar to Maps Raster API, the Maps Vector API serves data on different zoom level ranging from 0 to 22. For zoom level 0, the entire earth is displayed on one single tile, while at zoom level 22, the world is divided into 2 44 tiles.
The Maps Vector Service delivers geographic map data packaged in a vector representation of squared sections called vector tiles. Each tile includes pre-defined collections of map features (points, lines, road shapes, water polygons, building footprints, ect.) delivered in one of the specified vector formats. Format of the tile is formally described using protobuf schema.

Since 2006, Gisgraphy is a free, open source framework that offers the possibility to do geolocalisation and geocoding via Java APIs or REST webservices. Because geocoding is nothing without data, it provides an easy to use importer that will automatically download and import the necessary (free) data to your local database (OpenStreetMap, Geonames and Quattroshapes: more than 100 million entries). You can also add your own data with the Web interface or the importer connectors provided. Gisgraphy is production ready, and has been designed to be scalable(load balanced), performant and used in other languages than just java : results can be output in XML, JSON, PHP, Python, Ruby, YAML, GeoRSS, and Atom. One of the most popular GPS tracking System (OpenGTS) also includes a Gisgraphy client...Gisgraphy is a framework. As a result it's flexible and powerful enough to be used in a lot of different use cases. read more
if you use the premium servers, you can use the api key to test the webservices

Our atmosphere protects us from a hostile space radiation environment comprising high energy particles of solar and intergalactic origin. Solar radiation is significant during unpredictable and short lived solar flares and coronal mass ejections (CMEs); however, galactic cosmic radiation (GCR) is omnipresent. The GCR intensity varies with latitude, longitude, and time due to effects of solar activity on the interplanetary magnetic field, as well as the Earth's magnetic field. Space radiation collides with gases in the atmosphere, leading to a complex shower of high energy radiation, the intensity and composition of which varies spatially and temporally. Excessive exposure to radiation can damage DNA and lead to long-term health effects such as an increased risk of cancer. Resulting radiation levels at commercial aircraft altitudes are greater than at sea level due. Aircrew are classified as radiation workers in some countries; however, planning to limit their exposure, and monitoring, is generally lacking. Both real-time measurements and predictive models of radiation in the atmosphere are important to mitigate the radiation risk crew.
We host a RESTful API to models of cosmic ray induced ionising radiation in the atmosphere. The PARMA or CARI7 endpoints can be used to calculate Effective Dose or Ambient Dose Equivalent at a point.
The Route Dose API calculates the same quantities along a great circle route between two airports using CARI7.

IP2Proxy allows instant detection of anonymous proxy, VPN, TOR exit nodes, search engine robots (SES), data center ranges (PX2-PX10), residential proxies (PX10) and VPN provider name (PX11) by IP address. It also returns the threat type of the proxy (PX9 or higher). Visit https://www.ip2location.com/web-service/ip2proxy for further information.

GeoDataSource™ Web Service is a REST API enable user to lookup for a city by using latitude and longitude coordinate. It will return the result in either JSON or XML containing the information of country, region, city, latitude and longitude. Visit https://www.geodatasource.com/web-service for further information.

IP2Location web service providing a service to do a reverse lookup of an IP address to an ISO3166 country code, region or state, city, latitude and longitude, ZIP/Postal code, time zone, Internet Service Provider (ISP) or company name, domain name, net speed, area code, weather station code, weather station name, mobile country code (MCC), mobile network code (MNC) and carrier brand, elevation, usage type, address type and IAB category. There are also 7 categories of additional add-on response fields supported such as metro, olson time zone, translations and more. Refer to https://www.ip2location.com/web-service/ip2location for further information.

API for OpenAQ LCS

Positioning API accepts requests with radio network measurements and replies with corresponding location estimate. For more details and examples, see Developer's Guide. Cellular measurements are given in terms defined in 3GPP and 3GGP2 specifications, see the corresponsing documentation at http://www.3gpp.org.
