Abstract The acquisition of bathymetric data in shallower waters is difficult to attain using traditional survey methods because the areas investigate may not be accessible hydrographic vessels, due risk grounding. For this reason, use satellite detection depth (satellite-derived bathymetry, SDB) constitutes a particularly useful and also economically advantageous alternative. In fact, approach...

This research study addressed and compared 3D physical and empirical models for stereo-processing and the generation of digital surface models (DSMs) from different stereo highresolution (HR) sensors (Ikonos and QuickBird). The 3D physical model is Toutin’s Model (TM) developed at the Canada Centre for Remote Sensing, and the empirical model is the rational function model (RFM). The study also ...

The Ikonos one-metre earth observation satellite system offers the photogrammetric and remote sensing communities a significant new means for geospatial information collection, with the potential of pixel-level geopositioning precision. This paper addresses the subject of the metric accuracy potential of Ikonos Geo imagery for both 2D and 3D geopositioning. Photogrammetric approaches to metric ...

The most extensive use of Remote Sensing data is in land cover/land use (LCLU) studies by means of automated image classification. The general objective of this research is to develop an automatic pixel-based classification methodology with the aim to produce a Regional land use map congruent with the CORINE Land Cover legend. Starting point are detailed ground data, already gathered fostering ...

Ice storms are a recurring landscape-scale disturbance in the eastern U.S. where they may cause varying levels of damage to upland hardwood forests. High-resolution Ikonos imagery and semiautomated detection of ice storm damage may be an alternative to manually interpreted aerial photography. We evaluated Ikonos multispectral, winter and summer imagery as a tool for detecting forest canopy dama...
