Coordinates are required for every repeater entry. They are critical for enabling proximity-based features such as “near me” searches, mapping, and app functionalities. These tools are most effective when the coordinates reflect the actual location of the repeater.

• Coordinates must be provided in decimal format and should consist only of numeric values (e.g., `-122.4194`, `37.7749`).
• Cardinal directions (e.g., N, S, E, W) should not be included.
• Proper use of the negative sign is necessary for western and southern hemispheres.
• Coordinate converters are available whenever coordinates are requested to assist with formatting.

For repeater owners or trustees concerned about security, alternative or truncated coordinates can be used to protect the exact location of the repeater. - In such cases, RepeaterBook often centers the coordinates on the nearest city or a general area. - This ensures functionality for mapping and searches while preserving location privacy.

• If the exact coordinates of a repeater are known, this is indicated with an “exact coordinates are known” notation on the repeater's details page.
• A similar flag is included in the RepeaterBook API for developers.

It’s important to note that the exact location of many repeaters may not be known or displayed in RepeaterBook. While alternative coordinates maintain privacy, they may not accurately reflect the repeater's true placement.

By understanding the role and handling of coordinates, users can better utilize RepeaterBook’s tools and data for their needs.
