Il rilevamento geodetico tridimensionale integrato

Abstract

RIASSUNTO Oggi sono disponibili strumenti che associano ad ogni stazione topografica di misura una posizione ottenuta con misura GPS. -Il rilevatore può disporre in tempo reale di coordinate prodotte dalle misure di entrambi i sensori in un sistema di riferimento globale, direttamente in campagna. Si pongono perciò tre problemi di cui il primo è di carattere generale: 1) compensare misure classiche e misure GPS derivate (in genere non basi ma coordinate) in maniera tridimensionale e rigorosa; 2) innovare gli schemi di rilevamento tradizionali, pensati per sole misure topografiche o GPS; 3) verificare la precisione di schemi di misura – specie altimetrici – per i quali si faceva l’ipotesi approssimativa che il geoide coincidesse con l’ellissoide locale. Il lavoro proposto prende in esame questi problemi con esempi per ciascun aspetto. ABSTRACT Today they are integrated survey stations that made be possible to associate to every station a GPS positioning. The surveyor use directly in the field coordinates produced by the measures of both the sensors in a global reference system. They grows therefore three kind of problems, the first one is more general: 1) to adjust classical measures joint with derived GPS coordinates (you don't generally have baselines) in 3D and rigorous way; 2) to innovate the traditional survey schemes; 3) to verify the precision of measure schemes, specially regard heights. In the past we did the approximate hypothesis that the geoid and the local ellipsoid are coincided. The job takes in examination these problems with examples for every aspect.
