Instantly access empirical models of atmospheric density and composition that are recommended by the Committee on Space Research (COSPAR) for satellite drag calculations.

NRLMSISE-00 is recommended for composition calculations and was developed by the US Naval Research Laboratory.

JB2008 is a newer model and is recommended for density calculations at altitudes above 80 km. It was developed by Space Environment Technologies and the US Air Force Space Command.

The Atmosphere API wraps the original source code for both. It is free for research and development purposes and rate-limited to 1000 calls per day.

High energy galactic cosmic rays and bursts of solar energetic particles collide with nuclei of gases in the atmosphere, leading to a cascade of nuclear and electromagnetic reactions. The result is a complex mix of directly and indirectly ionising radiation, the intensity and composition of which varies spatially and temporally. Understanding this mix is important for a variety of applications, including estimating the exposures of aircrew, pilots, and frequent flyers during air travel.

The PARMA model, developed by the Japan Atomic Energy Agency (JAEA), can instantaneously estimate cosmic ray fluxes of neutrons, protons, ions, muons, electrons, positrons, and photons for a given date, latitude, longitude, and altitude. A comprehensive description of PARMA can be found in the publications here and here

The Terms and Conditions of PARMA are described here. Use of the API acknowledges you have read and agreed to those Terms and Conditions.

We provide an open RESTful API to the model and added functionality to calculate Effective Dose and Ambient Dose Equivalent using conversion coefficients. The API is free but usage is limited to 1000 API calls per day.

Amentum Pty Ltd is not responsible nor liable for any loss or damage of any sort incurred as the result of the use of the API.

The World Magnetic Model calculates the intensity and direction of the Earth's magnetic field on a specific date-time, geodetic altitude, latitude, and longitude. It is relied upon throughout the world for navigation, mineral exploration, atmospheric and space science, and is installed on billions of devices.

A comprehensive description of the World Magnetic Model, including its limitations, can be found here.

We provide a RESTful API for free access to the out-of-cycle Wolrd Magnetic Model (WMM2015v2) valid for years 2015.0 - 2020.0.

The Global Magnet API wraps the original WMM code which is available here.

Furkot provides Rest API to access user trip data. Using Furkot API an application can list user trips and display stops for a specific trip. Furkot API uses OAuth2 protocol to authorize applications to access data on behalf of users.

GeoDataSourceā„¢ 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.

Convert an OSGB36 easting and northing (British National Grid) to WGS84 latitude and longitude.

Since 2006, [Gisgraphy](http://www.gisgraphy.com) 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](http://www.openstreetmap.org/), [Geonames](http://www.geonames.org/) and [Quattroshapes](http://www.quattroshapes.com/): 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](http://www.gisgraphy.com) if you use the premium servers, you can use the api key to test the webservices

Publishes 360 photos to Google Maps, along with position, orientation, and connectivity metadata. Apps can offer an interface for positioning, connecting, and uploading user-generated Street View images.

Our Route Optimization API solves the so called vehicle routing problem fast. It calculates an optimal tour for a set of vehicles, services and constraints

Positioning API for making location requests.

HERE Tracking is a cloud product designed to address location tracking problems for a wide range of Location IoT industry verticals. HERE Tracking exposes a set of REST APIs and client libraries to enable location tracking and geo-fencing for a variety of device form-factors including small-footprint (small memory and processing power) devices. HERE Tracking also includes end-user applications on mobile and web to be used as reference apps to demonstrate the product capabilities.

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, and usage type. 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.

IP2Proxy allows instant detection of anonymous proxy, VPN and TOR exit nodes and search engine robots (SES) by IP address. Visit https://www.ip2location.com/web-service/ip2proxy for further information.

The API returns the location of an IP address (country, region, city, zipcode, latitude, longitude) and the associated timezone in XML, JSON or plain text format.

Access the most exhaustive, accurate and up-to-date collection of global and hyper-local geocoded events and activities across a wide range of categories and genres

The GeoDB API focuses on getting global city and region data. Easily obtain country, region, and city data for use in your apps!

  • Filter cities by name prefix, country, location, time-zone, and even minimum population.
  • Sort cities by name, country code, elevation, and population - or any combination of these.
  • Get all country regions.
  • Get all cities in a given region.
  • Display results in multiple languages.
  • RESTful API adheres to industry best-practices, including HATEOAS-style links to facilitate paging results.
  • Backed by cloud-based load-balanced infrastructure for resiliency and performance!
  • Data is periodically refreshed from GeoNames and WikiData.


  • Since the database is periodically updated, this may very rarely result in certain cities being marked deleted (e.g., duplicates removed). By default, endpoints returning city data will exclude cities marked deleted. However, in the unlikely event that this occurs while your app is paging through a set of affected results - and you care about the paged results suddenly changing underneath - specify includeDeleted=SINCE_YESTERDAY (or SINCE_LAST_WEEK if you're really paranoid!).

Useful Resources

The Miataru API is very simple and straight forward. Generally you're posting (HTTP POST) a JSON formatted request to a service method locations and you get back a JSON formatted answer. Please take into consideration that this has the request-for-comment status and that it can change while there's work done on client and server applications. Versioning therefore is done by prepending the version number - /v1/ for version 1 - to the method call.

Worldwide forward and reverse geocoding

Welcome to the Daymet Single Pixel Extraction Tool API. You can use this API to download daily surface data within the Daymet database in a `csv` or `json` format for a single point. This API allows users to query a single geographic point by latitude and longitude in decimal degrees. A routine is executed that translates the (lon, lat) coordinates into projected Daymet (x,y) Lambert Conformal Coordinates. These coordinates are used to access the Daymet database of daily interpolated surface weather variables. Daily data from the nearest 1 km x 1 km Daymet grid cell are extracted from the database. If you would like to learn how to automate the download of multiple locations for the Daymet Single Pixel Extraction Tool, click [here](https://github.com/ornldaac/daymet-single-pixel-batch).
