hammap — ham radio map for POTA, SOTA and repeaters
hammap is a free interactive map for radio amateurs. It shows POTA park boundaries as real areas rather than single points, together with SOTA summits, repeaters, activation spots shared by other operators, the Maidenhead grid locator overlay, DXCC entities, CQ and ITU zones and administrative boundaries — on one map.
Because the park areas are real geometry, hammap works out which parks overlap for an n-fer activation and which summits fall inside a park boundary. Every object has a stable address, so a link points at exactly the place you meant.
The map is open to everyone. An account adds photos, comments, activation spots and the full range of layer controls.
