## What is Chronomap in Maritime?

This app allows you to record, search, and display information about where, when, and what happened in the ocean—from its birth to deep-sea exploration—in various formats. It shares a database with the integrated « Chronomap When-Where-What Database. » The "When-Where-What Database" is a project where users collaborate to build a comprehensive database that covers all historical events from the origin of the universe to the endless "now," regardless of the field. It aims to accurately display not only "when" but also "where" events occurred, emphasizing both temporal and spatial distances.
