# Rivermap > https://rivermap.online An interactive global river map and database that visualizes world rivers, streams, and artificial waterways (canals). It provides detailed geographic insights into hydrological networks, river lengths, and containment hierarchies. All rivers are hand-drawn and precisely checked by the owner. ## Core Features - **Interactive Map:** Global visualization of rivers and canals using custom path renderings and Google Maps. - **Visual Classification:** Rivers are color-coded based on their containment hierarchy and discharge paths (e.g., flowing directly into the sea vs. flowing into other rivers). - **River Database:** Searchable index of unique river records, localized in German and English, with verified coordinates and lengths. - **Embedded Maps:** Ability to configure and embed specific map sections onto third-party websites. ## URL Structure & API Routing All detail pages support clean URL routing for both German (default) and English languages. Detail pages contain unique descriptions (native to Rivermap) or syndicated Wikipedia content in multiple languages. - **German Detail Page (with tributaries):** `/river/{RiverID}` - **English Detail Page (with tributaries):** `/en/river/{RiverID}` - **German Direct Map Link:** `/d/{RiverID}` - **English Direct Map Link:** `/en/d/{RiverID}` - **Embed Interface:** `/embed` or `/embedded` ## Data Hierarchy & Classifications Rivers are categorized from 1 to 6 based on their hydrological connection: - **Category 1:** Flows directly into the sea / ocean. - **Category 2:** Flows into a Category 1 river. - **Category 3-5:** Successive inflowing river hierarchies. - **Category 6 (Canal):** Artificial waterways.
