OFFICIAL DATA & DOCUMENTATION

Go to the source.

A curated starting point for orbital elements, Earth observation, geospatial standards and platform documentation. Access policies and service capabilities belong to each provider.

ORBITAL ELEMENTS

CelesTrak

Documentation for general perturbations data formats. Start here to understand the element records you are requesting before selecting a propagation workflow.

EARTH OBSERVATION

NASA Earthdata

A starting point for discovering NASA Earth science data, services and learning resources. Follow dataset-specific documentation for interpretation and access.

SEARCH & METADATA

NASA CMR

The Common Metadata Repository search API documentation explains how to find collections and granules using supported query parameters.

POSITIONING

GPS.gov

Official background on the Global Positioning System and its components. Use it to distinguish satellite signals from a device’s location interface.

CATALOG STANDARDS

STAC specification

The SpatioTemporal Asset Catalog specification describes common structures for geospatial assets and their metadata. Read the applicable core and extension documents together.

GEOMETRY FORMAT

GeoJSON / RFC 7946

The standard for GeoJSON defines its geographic object types and coordinate conventions. Useful when passing points, lines or polygons between systems.

REFERENCE FRAMES

NASA SPICE

The SPICE frame documentation provides deeper background on coordinate systems and frame relationships. A useful reference when simple globe labels are no longer enough.

WEB VISUALIZATION

Three.js

Official documentation and examples for browser graphics. Treat rendering as a layer around your data model, with explicit transforms between the two.

iOS LOCATION

Apple Developer

Guidance on choosing a location authorization request. Match the request to the feature the user is trying to use, then verify current platform requirements.

ANDROID LOCATION

Android Developers

Official location permission guidance for Android applications. Check the behavior required by your target platform and the scope of the feature.

CSS VISUAL LAYERS

W3C CSS transforms

The CSS transforms specification is a primary reference for the behavior behind transformed interfaces. The globe guides explain its practical role in this site.

CONTENT SYNDICATION

Atom / RFC 4287

The Atom syndication specification defines the feed format used by this site’s complete-content feed and news-only feed.
