Relief Mapper — Sector mapping, simplified

Free · In the browser · No install

Flight sectors in exact hectares — no paid platforms, no complex software.

Draw or import your operations area; ReliefMapper splits it into sectors of the size you set, shares it among pilots in equal zones and exports one KML per flight.

Using it is free. To save and share projects, a free Microsoft or Google account is required — your files live in your own OneDrive or Google Drive, not on our servers.
