Real-Scale Island Area and Coastline Estimation using Only its Place Name or Coordinates

ArXi:2605.11267v1 Announce Type: new Accurate measurement of island area and coastline length is crucial for coastal zone monitoring and oceanographic analysis. However, traditional measurement and mapping methods usually rely heavily on orthophotos, expensive airborne depth sensors, or dense ground control points, which face serious limitations of high labor costs, time-consuming efforts, and low operational efficiency in vast and inaccessible open sea environments.
