Digital Elevation Models (DEMS)
A digital elevation model (DEM) or sometimes referred to as a digital terrain model (DTM) is a quantitative representation of the topography of the Earth. DEMs are used as a source of elevation (and to create other digital terrain models) for many different purposes
Digital Terrain Modeling
Digital Terrain Modeling is the process of simulating or representing the relief and patterns of a surface with numerical and digital methods. It has always been an integral component to geology related fields such as geomorphology, hydrology, tectonics and oceanography but over the past decade has also become a major component to non geophysical applications such as GIS modeling, surveying and land use planning.
Terrain Models are derived from data represented by digital elevation models (DEMs) and can include shaded relief models, slope and aspect models, perspective scene generation, and drainage basin analysis (and other models).
Geologic Application of RadarSat S2 Mode Data in Northern Nova Scotia
Poster created for a paper and presentation on a project used RADARSAT S2 beam mode SAR imagery and ERDAS Imagine . The project used RADARSAT S2 beam mode SAR imagery and ERDAS Imagine together to provide 3D models representing various geological terrain features.
Geologic Application of RadarSat S2 Mode Data
RADARSAT images can provide geologists with an exceptional and correlative data source with respect to geological contacts, structures, and lineaments. This project is an attempt to provide some distinct examples of various geological structures in Nova Scotia that can easily be detected using RADARSAT imagery. Since Nova Scotia is a well-mapped and explored area, geological and geophysical data is easily accessible to accompany the radar data. RADARSAT imagery is especially …
Seamless Aerial Photograph Mosaic
Sample of an seamless 1:10000 scale color aerial photograph mosaic of Halifax, Nova Scotia that I generated using PCI OrthoEngine software to seamlessly combine seven individual ortho photos into 1 image.
Aerial Photograph
Aerial photography is the method of taking of photographs of the ground from an elevated position. The term usually refers to images in which the camera is not supported by a ground-based structure. Cameras may be hand held or mounted, and photographs may be taken …
Remote Sensing
Remote sensing involves the use of technical instruments or sensors to record reflected or emitted energy and then processing, analyzing, and applying that information to determine the spectral and spatial relations of distance objects and materials. …
