What is mapmania?

It simply is a database for the map obssessed. It is a side project born out of curiosity.

Can I use the data?

As long as you respect the original copyright of maps absolutely! These maps are sourced from various sources (from reddit and Wikipedia as of this writing) and each map is referenced back to its submitter and source. Please respect those.

Is there a copyright violation?

Hopefully not. None of these maps have originated on this site. They are sourced from other sites that have already published them. But copyrights are complex and difficult to get right, so if there are any issues for concern on any of the maps, please do reach out with details. Contact details are below.

What are scores?

We wanted to get some sense of popularity for each map. It is important to note that this is not quality, quality is a different metric than popularity. Since we could not devise a mechanism to measure quality by solely using algorithms, we went for popularity instead.

All scores are between 0 and 100 and they are logarithmic. Meaning it is exponentially more difficult for maps to have higher scores, there are practically only two maps that have a score of 100, one from each of the sources.

For maps sourced from reddit, score is based on the number of votes that a map received from reddit community in the corresponding subreddit. It is calculated by the following formula: 10 x log(1 + 1023 x (votes_for_the_map_in_question / max_votes_for_any_map), 2).

For maps sourced from Wikipedia, score is based on the number of English language Wikipedia pages that make a reference to the map in question. It is calculated by the following formula: 10 x log(1 + 1023 x (number_of_english_pages_linking_to_the_map / max_number_of_pages_linking_to_any_map), 2).

Each of these formulas will always give a score between 0-100.

Giving back

Mapmania currently runs on two dedicated servers, powered by energy from hydropower. Idle time on these servers is donated to World Community Grid to support research into important global humanitarian causes. By using mapmania, you are also supporting humanitarian research.

Who is the team?

Mapmania is the brainchild of Ilker Temir, a maker, entrepreneur, product manager and engineer. Sailing, history (as a result, marimetime history) and technology are my passions. You can contact me at ilkerilkertemir.com.

Although not part of the team officially, Alex Levin also played an influential role with his passion about history, addiction to reddit, endless set of ideas and most importantly with his TimeDB project.
