CONT

Poseidon : Brother of Zeus. Olympian god who spent much of his time in his own watery kingdom. God of the sea and easily identifiable by his trident and chariot which could be used to create massive shifts in the waters.

OBS

Poseidon : term used at Natural Resources Canada-Earth Sciences Sector.

  • Mythologie
CONT

Poséidon [...] est le dieu grec des mers et des océans, des gouffres et des séismes. Il est aussi le seigneur des chevaux. Son symbole est le trident, qu'il reçoit des Cyclopes pendant la Titanomachie. Il correspond au Neptune romain.

Record 4 2005-10-03

English

Subject field(s)
  • Remote Sensing
CONT

The TOPEX/Poseidon(T/P) altimetry data were obtained mountainous topography may lead the altimeter to lock off completely, requiring some time to lock on again, even over water and for narrow rivers, the instrument may deliver no reliable measurement at all. In other cases, the instrument could remain locked on water while the satellite is well ahead of the water body, since the reflected signal on water has more power than the reflected signal on land. This may cause a geometric error that could reach several meters for some regions. In order to minimise potential contamination of the T/P signal by land reflections, and at the same time to retain a sufficiently large number of altimeter measurements on water, we performed a geographical selection of the data.

OBS

geometric error: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Domaine(s)
  • Télédétection
CONT

Lors de l'interpolation, la couronne telle qu'elle sera interprétée par l'opérateur dans ArcMap aura la forme cerclée de rouge ce qui amènera à pointer un apex différent de l'apex réel. Cette erreur géométrique, qui ne peut guère excéder le mètre, se combine à l'erreur de pointé qui elle peut être de l'ordre de grandeur du mètre, pour donner un intervalle d'erreur d'un mètre pouvant lui-même se déplacer à l'intérieur d'une plage de 20 cm (probable ordre de grandeur de cette erreur géométrique).

OBS

[Il existe] 3 méthodes pour évaluer les erreurs : [1] [les] zones de test définies sur l'image elle-même [,] on ne peut pas exclure une certaine corrélation entre les zones d'entraînement et les zones de test, dues à la proximité spatiale [;] [2] les cartes ou images provenant d'autres sources [;] [3] les échantillons de terrain.

OBS

erreur géométrique : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

Improve the accuracy and resolution of the gravity field along repeat tracks of ERS-1/2, Geosat/ERM and Topex/Poseidon and test these results with precise shipboard gravity. This will involve incorporating the latest orbits and tide corrections into the raw satellite altimeter measurements as well as averaging profiles along repeat tracklines to improve accuracy and resolution.

The Ocean Topography Experiment(TOPEX/Poseidon) is an advanced satellite radar altimetry system which provides global sea level measurements with an unprecedented accuracy. The sea level data from TOPEX/Poseidon is used to determine global ocean circulation and to increase the knowledge of the interaction of the oceans and the atmosphere.
