The across-shelf structures of the ocean circulation and the associated sea surface height (SSH) variability are examined on the west Florida shelf (WFS) for the 3-yr interval from September 1998 to December 2001. Five sets of characteristic circulation patterns are extracted from 2-day, low-pass-filtered data using the self-organizing map: extreme upwelling and downwelling structures with stro...
The Institute of Geomatics (IG) and the Instituto Geográfico Militar de Bolivia (IGM) are conducting an analysis on the feasibility of kinematic airborne gravimetry with strapdown inertial and satellite navigation technologies for geoid determination. This research is being conducted within the frame of the TERRA project which is funded with cooperation funds of the Spanish Ministry of Economy....
Operational multi-channel algorithms for deriving sea surface temperature (SST) from satellite data are derived using theoretical models of infrared radiation transfer through the atmosphere or by regression of satellite data with ground-based observations. In both cases the algorithm derivation implies a “first-guess” of the water vapour content along the atmospheric path between the satellite...
ZY-3 is the first civilian high resolution stereo mapping satellite, which has been launched on 9th, Jan, 2012. The aim of ZY-3 satellite is to obtain high resolution stereo images and support the 1:50000 scale national surveying and mapping. Although ZY-3 has very high accuracy for direct geo-locations without GCPs (Ground Control Points), use of some GCPs is still indispensible for high preci...
Gravity field recovery from satellite altimetry provides global marine coverage but lacks the accuracy and resolution needed for many exploration geophysics studies. The repeating ground tracks of the ERS-1/2, Geosat, and Topex/Poseidon altimeters offer the possibility of improving the accuracy and resolution of gravity anomalies along widely spaced (∼40-km spacing) tracks. However, complete oc...
