Journal of Coastal Research, 00(0), 000–000. Coconut Creek (Florida), ISSN 07490208. Accurate elevation information is a necessity for conservation and management of tidal salt marshes where elevation differences can be as little as 2 m and ...

Digital Terrain Model (Digital Terrain Model acronym DTM) is arbitrary use of a large number of coordinates in three-dimensional x, y, z coordinates of the point on the ground for a form of Statistics said that the terrain surface morphology is the number of attribute information is a space location characteristics and attributes of the terrain described the figures, initially for the automatic...

This paper proposes the localization algorithm that estimates translation parameters of an aircraft by comparing the sampled elevation map recovered from aerial sequence images, and the digital elevation model (DEM) with the given orientation and altitude parameters obtained from a gyroscope. It consists of two stages: recovering the sampled elevation map from multiple aerial image pairs and ma...

This paper describes the implementation of three methods for fitting surfaces: linear, quintic and stochastic. It uses qualitative (visual) and quantitative (statistical) criteria to compare the three approaches. The digital terrain model is based on a triangular irregular network (TIN) structure and the comparison is performed using a mathematically defined function and real data obtained from...

With the rapid development of Earth observation technologies, raster data has become the main Geographic Information System (GIS) data source. GIS should be able to manage and process huge raster data sets. In this paper, the problem of 3-dimensional visualization of huge DEM data sets and its corresponding image data sets in GIS was addressed. A real-time delamination method based on raster ch...

SAR Interferometry (InSAR) provides data that contain information relating to the phase and coherence components of the backscattered radar signals. Phase information is used to derive Digital Elevation Models (DEM). This paper presents the results of an analysis of the accuracy of InSAR DEM derived from ESAR L-band airborne repeat-pass fully polarimetric InSAR data, which were acquired over Th...

Digital elevation model (DEM) generation from stereo images is an effective and economical method in topography mapping. This paper used the stereo pair methodology to generate the digital elevation model (DEM) from PRISM (Panchromatic Remote-Sensing Instrument Satellite) sensor which is onboard of ALOS (Advanced Land Observing Satellite). The pair of forward-backward is used as stereoscopic im...

Information about the shape of the Earth’s surface is important in many applications as it helps users to visualize and analyze geographic problems accurately in 3D. This paper focuses on the InSAR technique of generating Digital Elevation Models (DEM) by using InSAR data acquired from an airborne platform. The data cover a study area of 4 km x 3 km located in Thetford Forest, East Anglia, Unit...
