API for OpenAQ LCS

Space has a hostile radiation environment that increases the risk of cancers in humans and malfunctions in spacecraft electronics. The types of space radiation of primary concern are:
Galactic Cosmic Rays from outside our solar system generated by
supernovae and other phenomena;
Solar Energetic Particles produced by the Sun during intense and
sporadic bursts of activity; and
Trapped Radiation: energetic particles confined by Earth's magnetic
field, usually comprising an inner belt of mostly high energy protons
and an outer belt dominated by lower energy electrons and plasma.
Understanding the space radiation environment for a particular mission profile is becoming increasingly important. Commercial off-the-shelf electronic components that aren't resilient to space radiation are now prevalent. Longer duration missions to cislunar space, Mars, and beyond are placing astronauts at greater risk of radiation exposure.

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.

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.
Breaking changes from v1:
JSON fields
altaccuracy, baselat, baselng, cellparams, pilotpower, pnoffset, powrx, rxlevel,
have been deprecated and replaced with
altAccuracy, baseLat, baseLng, cellParams, pilotPower, pnOffset, rss, rxLevel
respectively.
Dependent parameters combined as a subobject.
CDMA, GSM, WCDMA, TD-SCDMA and LTE local identification parameters for serving cell moved under localId property.
GSM neighbor global ID: lac and cid for neighbor cell moved under globalIdentity property.

API de Dados Abertos com dados processados pelo grupo de monitoramento de Queimadas do INPE.

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

Background
This RESTful API provides information about physical VA facilities. Information available includes
geographic location, address, phone, hours of operation, and available services.
VA operates several different types of facilities, the types represented in this API include:
Health Facilities (vha)
Benefits Facilities (vba)
Cemeteries (nca)
Vet Centers (vc)
To read an FAQ on how wait times are calculated, click the "For more information" link on this page.
Getting Started
Base URLs
The base URLs for the VA Facilities API in the various environments are:
Sandbox: https://sandbox-api.va.gov/services/va_facilities/v0
Production: https://api.va.gov/services/va_facilities/v0
Authorization
API requests are authorized through a symmetric API token, provided in an HTTP header with name apikey.
Response Formats
Clients may request several response formats by setting the Accept header.
application/json - The default JSON response format complies with JSON API. This media type is not available for bulk requests using the /facilities/all endpoint. It will return 406 Not Acceptable.
application/geo+json - GeoJSON-compliant format, representing each facility as a feature with a point geometry.
application/vnd.geo+json - Deprecated. Prefer application/geo+json.
text/csv - Available for the bulk download operation only. Some structured fields are omitted from the CSV response.
Response Elements
Some data elements within the response are only present for facilities of a given type:
The patient satisfaction scores contained in the satisfaction element are only applicable
to VA health facilities.
The patient wait time values contained in the wait_times element are only applicable to
VA health facilities.
The list of available services in the services element is only applicable to VA health and
benefits facilities.
The operational hours special instructions contained in the operationalhoursspecial_instructions element is only applicable to VA health and Vet Center facilities.
Facility ID Formats and Constraints
A facility ID has the format prefix_stationNumber. The prefix is one of nca, vc, vba, or vha. Cemeteries may be national (VA) or non-national; non-national cemeteries have the station number prefixed with an s. There are no other constraints on the format. Examples:
Health: vha_402GA
Benefits: vba_539GB
National cemetery: nca_063
Non-national cemetery: nca_s1082
Vet center: vc_0872MVC
Mobile Facilities
The mobile health facilities move regularly within a region. If a facility comes back from this API with "mobile": "true", the latitude/longitude and address could be inaccurate. To get the exact current location, please call the number listed.
Deprecations
activestatus field is deprecated and replaced with operatingstatus.
application/vnd.geo+json media type is deprecated and replaced by application/geo+json

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.
