Credits & Data Sources
This page lists the main external data sources used by ISS-over.me and how they are credited.
Geographic data
City names, coordinates and population values are based on the GeoNames geographical database.
This work uses data from GeoNames.org, which is made available under the Creative Commons Attribution 4.0 International License (CC BY 4.0) .
The original data has been filtered, subsetted and reformatted for use on this site.
Weather data
Cloud cover forecasts are provided by The Norwegian Meteorological Institute (MET Norway), using the MET Weather API (Locationforecast/2.0).
This data is licensed under the Creative Commons Attribution 4.0 International License (CC BY 4.0) .
The original data is cached, subsetted (extracting only cloud cover metrics) and reformatted for display on this site. This service is not endorsed by or affiliated with MET Norway.
Meteor shower data (IAU MDC)
Meteor shower identifiers, radiants and related catalog fields are derived from the International Astronomical Union (IAU) Meteor Data Center (MDC) shower lists (established showers).
The meteor shower data on this site is subsetted, normalized and reformatted for display and for internal calculations. The IAU MDC is not affiliated with or endorsing this project.
Meteor shower activity windows (IMO-style calendar)
Peak dates, typical active windows and intensity estimates (e.g., ZHR) are based on publicly available meteor shower observing references in the style of the International Meteor Organization (IMO) annual meteor shower calendar.
Where used, this information is merged with IAU MDC identifiers to improve consistency. This project is not affiliated with or endorsed by the IMO.
Constellation guidance
Monthly “what to look for” constellation suggestions are generated from an internal reference dataset (north/south hemisphere, by month) to help users orient themselves in the night sky.
These are general orientation aids and do not represent official sky charts.
Orbital and astronomy data
International Space Station pass estimates are based on publicly available orbital information and standard astronomy calculations.
Additional astronomy data may use publicly available information from space agencies and scientific organisations where noted.
Project note
ISS-over.me is an independent project and is not affiliated with NASA, ESA, Roscosmos, JAXA, CSA, the IAU Meteor Data Center, the International Meteor Organization, or any other space/science organisation.
All timings are approximate. Local conditions such as weather, light pollution and obstructions will affect what is actually visible.
