Taking the Quickbird optical satellite imagery of the small watershed of Beiyanzigou valley of Qixia city, Shandong province, as the study data, we proposed a new method by using a fused image of topography with remote sensing imagery (RSI) to achieve a high precision interpretation of gully edge lines. The technique first transformed remote sensing imagery into HSV color space from RGB color s...

Land use is an indispensable prerequisite for credible causes and consequences investigation of global environment changes. With the increasing availability of very high resolution remote sensing imagery, more accurate and effective analysis of land use is becoming possible. However, the traditional method of imagery interpretation is focused on pixel-based analysis, which has fundamental limit...

Satellite remote sensing has revolutionized modern oceanography, providing frequent synoptic-scale information that can be used to deduce ocean processes. However, it is often difficult to extract interpretable patterns from satellite images, as data sets are large and often non-linear. In this methodological paper, we describe the self-organizing map (SOM), a type of artificial neural network ...

We present an approach for tracking water courses in satellite images, a general strategy for tracking and recognising features in computer vision tasks on satellite images. Our approach is related to recent work in automatic image interpretation and urban scene analysis. We report a method for image recognition from multi-spectral SPOT satellite imagery, based on the different response of wate...

This paper discusses a planner-based approach to automating data production tasks, such as producing fire forecasts from satellite imagery and weather station data. Since the set of available data products is large, dynamic and mostly unknown, planning techniques developed for closed worlds are unsuitable. We discuss a number of techniques we have developed to cope with data production domains,...

Aeolian process and subsequently soil erosion are key factors in dryland environments. Such phenomena are related not only to geoecological factors (lithology, topography, and climatology) but also to land-use and plant cover changes. Formation of new sand dunes in Damghan explains the development of human activities over the past. The aim of this study is to explain the land use changes and th...

Determining the location and orientation of vehicles in satellite and airborne imagery is a challenging task given the density of cars and other vehicles as well as the complexity of the environment in urban regions around the world. We describe an accurate and flexible method for detecting vehicles using a template-based directional chamfer matching approach, and vehicle orientation estimation...

There is an emerging consensus that protected areas are key in reducing adverse land-cover change, but their efficacy remains difficult to quantify. Many previous assessments of protected area effectiveness have compared changes between sets of protected and unprotected sites that differ systematically in other potentially confounding respects (e.g. altitude, accessibility), have considered onl...

The proliferation of nuclear weapons poses great threat to international peace and security. How to strengthen the non-proliferation regime has become a central question. In May 1997, the IAEA Board of Governors adopted the Additional Safeguards Protocol to improve its ability to detect the undeclared production of fissile material. This new strengthened safeguards system has opened the door fo...

Using snakes to extract buildings from satellite imagery such as IKONOS and Quickbird is an active activity in remote sensing society. Building extraction from satellite imagery has more than 20 years of history but the automated extractions are still undergoing developmental stages due to increasing image variation, required level of details and higher resolution imagery are acquired. This pap...
