TitleDateViewsBrief Description
Air-Stream Temperature Correlation In Forested And Urban Headwater Streams In The Southern Appalachians 2014 957 Air temperature can be an effective predictor of stream temperature. However, little work has been done in studying urbanimpacts on air-stream relationships in groundwater-fed headwater streams in mountainous watersheds. We applied waveletcoherence a...
Anisotropic Reflectance Correction Of SPOT-3 HRV 2002 121 The problem of anisotropic reflectance in mountainous terrain is well known. It was required to determine the efficacy of anisotropic reflectance correction (ARC) of imagery acquired over the western Himalaya. The Minnaert correction procedure was ev...
An Efficient Method For Mapping Flood Extent In A Coastal Floodplain Using Landsat TM And DEM Data 2001 168 An efficient and economical method for mapping flooding extent in a coastal floodplain is described. This method was based on the reflectance features of water versus non-water targets on a pair of Landsat 7 Thematic Mapper (TM) images ( before and ...
Flood Modeling In The Coastal Plains And Mountains: Analysis Of Terrain Resolution 2010 608 The number of flood disasters has increased worldwide in recent decades. Identifying the optimal resolution or scale at which to represent digital terrain models (DTMs) is critical in order to improve our ability to accurately and efficiently model f...
Flood Modeling Using A Synthesis Of Multi-Platform LiDAR Data 2013 143 This study examined the utility of a high resolution ground-based (mobile and terrestrial) Light Detection and Ranging (LiDAR) dataset (0.2 m point-spacing) supplemented with a coarser resolution airborne LiDAR dataset (5 m point-spacing) for use in ...
Land Cover Classification Using Landsat TM Imagery In The Tropical Highlands: The Influence Of Anisotropic Reflectance 1998 641 Despite the tremendous attention given to conservation projects in the Neotropics, few published studies have documented remote sensing studies in tropical highland areas. Even fewer publications have addressed the use of topographic normalization me...
Modeling Flooding Extent Due To Hurricane Floyd In The Coastal Plains Of North Carolina 2000 70 In this article two modeling approaches were developed based on the use of US Geological Survey digital elevation model (DEM) data. These models were utilized to delineate the extent of flooding induced by precipitation from Hurricane Floyd in a port...
Remote Sensing And Geomorphometry For Studying Relief Production In High Mountains 2003 718 Mountain topography is the result of highly scale-dependent interactions involving climatic, tectonic, and surface processes. No complete understanding of the geodynamics of mountain building and topographic evolution yet exists, although numerous co...
Spatial Characterization, Resolution, And Volumetric Change Of Coastal Dunes Using Airborne LIDAR: Cape Hatteras, North Carolina 2002 781 The technological advancement in topographic mapping known as airborne Light Detection and Ranging (LIDAR) allows researchers to gather highly accurate and densely sampled coastal elevation data at a rapid rate. The problem is to determine the optima...
Techniques For GIS Modeling Of Coastal Dunes 2002 918 Coastal dunes present a unique problem to coastal scientists because of the dynamic nature of most coastal dune systems. Coastal dunes can change shape quickly and frequently due to storm-generated winds and waves. Prevailing winds can transport sign...
