Thiessen polygon method

From Glossary of Meteorology

A method of assigning areal significance to point rainfall values.
Perpendicular bisectors are constructed to the lines joining each measuring station with those immediately surrounding it. These bisectors form a series of polygons, each polygon containing one station. The value of precipitation measured at a station is assigned to the whole area covered by the enclosing polygon.


método de los polígonos de Thiessen

Un método que asigna qué tan significativa es un área para los valores puntuales de precipitación.

Se construyen bisectrices perpendiculares a las líneas que unen cada estación de medición con las líneas que la rodean inmediatamente. Estas bisectrices forman una serie de polígonos, y cada polígono contiene una estación. El valor de precipitación medido en una estación se asigna a toda el área cubierta por el polígono circundante.
