Land use and land cover (LULC) was mapped using historical aerial photos (1940) and contemporary QuickBird satellite imagery (2003) for a 100 km2 area covering portions of Erie Township, Michigan, and Toledo, Ohio on the western end of Lake Erie. This area serves as a microcosm of conditions elsewhere on the Great Lakes coast, containing a range of human-altered to natural landscapes. Geographi...

As the initial investigation on disaster occurrence, it is very important for reducing economical losses to obtain timely observation of damages especially in metropolis. In such situation, information on changed area obtained from aerial photo analysis is promising. In this study, we propose a change detection approach objected for metropolis right after the disaster with automatic image proce...

Abstract Plant growth and biomass assessments are required in production and research. Such assessments are followed by major decisions (e.g., harvest timing) that channel resources and influence outcomes. In research, resources required to assess crop status affect other aspects of experimentation and, therefore, discovery. Destructive harvests are important because they influence treatment s...

This paper deals with the various aspects of the Gorizia old downtown (Italy) 3D virtual model production obtained by a suitable integration of laser and imaging data, both acquired either by means of a helicopter and a terrestrial surveying. The virtual reconstruction can be compare with different perspective maps of the city to underline its transformation. An aerial high-density (15 points/m...

Recent development of the user-friendly software package “Co-registration of Optically Sensed Images and Correlation” (COSI-Corr), which allows for automatic and precise ortho-rectification, co-registration, and sub-pixel correlation of pushbroom satellite and aerial images, has enabled Earth’s surface dynamics to be accurately monitored using optical imagery [1]. This technique compares two im...

More than forty-five years after the assassination of U.S. President Kennedy theories continue to circulate suggesting that the accused assassin, Lee Harvey Oswald, acted as part of a larger conspiracy. It has been argued, for example, that incriminating photographs of Oswald were manipulated, and hence evidence of a broader plot. We describe a detailed 3-D analysis of the Oswald photos to dete...

Earthquakes are one major cause for the loss of many lives and properties in many regions around the world. In this project we develop algorithms based on aerial images and neural networks to better assess the risk of earthquakes for buildings. The algorithm consists of two major parts: extraction of buildings footprints from aerial photos and classification of structure type with neural networ...

A B S T R A C TIntroduction: Craving to methamphetamine is a significant health concern and exposure to methamphetamine cues in laboratory can induce craving. In this study, a task designing procedure for evaluating methamphetamine cue-induced craving in laboratory conditions is examined. Methods: First a series of visual cues which could induce craving was identified by 5 discussion sessions b...

0099-1112/08/7411–1325/$3.00/0 © 2008 American Society for Photogrammetry and Remote Sensing Abstract Due to the significant time and cost requirements of traditional mapping techniques, accurate and detailed habitat maps for large areas are uncommon. This study investigates the application of Ikonos Very High Resolution (VHR) images to habitat mapping in the rugged terrain of Hong Kong’s count...
