  • Remote sensing of soil degradation: Introduction

    In the 21st century, mapping and monitoring the occurrence of soil degradation will be an important component of successful land management. Remote sensing, with its unique ability to measure across space and time, will be an increasingly indispensible tool for assessing degradation. However, much of the recent experience and progress in using remote sensing and other geospatial technologies to ...

  • Coastline Change Detection Using Remote Sensing

    Coast is a unique environment in which atmosphere, hydrosphere and lithosphere contact each other. Coastline is one of the most important linear features on the earth’s surface, which display a dynamic nature. Coastal zone, and its environmental management requires the information about coastlines and their changes. This paper examines the current methods of coastline change detection using ...

  • Mangroves of Godavari – Analysis Through Remote Sensing Approach

    Abstract  The expansion of agriculture and aquaculture farms in the coastal areas has led to conversion of mangroves in the recent past. The extent of mangroves has also changed due to the erosion of mangroves along the coast and accretion near river mouths, leading to the formation of new mangrove areas. This study has been undertaken in the mangroves of the Godavari estuary, Andhra ...


  • Map Algal Blooms with Satellite Remote Sensing Technology

    The quality of water bodies is a key determinant in the usability of the resource for the purpose required. It is therefore of great importance to managers of hydrologic resources to be able to confidently tell the status of their water resource. One of the major problems in the quality of surface water bodies is the blooming of algae and blue green algae. Algal blooms can result in ecological, ...

  • Remote sensing of emissions: new technologies and recent work

    The Second International Workshop on Remote Sensing of Emissions: New Technologies and Recent Work was held April 1-3, 2008. The workshop was sponsored by the U.S. Environmental Protection Agency's (EPA) Office of Air Quality Planning and Standards at Research Triangle Park (RTP), Office of Research and Development (RTP), and Office of Solid Waste and Emergency Response (HQ). At the workshop, ...

  • Air temperature retrieval from remote sensing data based on thermodynamics

    A new approach to retrieving air temperature from land surface temperature is presented. The new method is based on thermodynamics. Two important parameters, namely crop water stress index and aerodynamic resistance, were used to build a quantitative relationship between the land surface temperature and the ambient air temperature. The method was applied using MODIS satellite data for a location ...

  • Why only few CDM projects? The case of reforestation projects and remote sensing

    CDM projects have large potentials but also face significant obstacles that have so far limited their applicability. Two serious problems that an effective contracting faces are the presence of private information and the lack of sufficiently precise output measures. In a principal–agent framework, where local landowners are the agents and have private information about their costs, we ...

  • Remote sensing and geographic information system for appraisal of salt-affected soils in India

    Received for publication January 23, 2009. Quantification of the nature, extent, and spatial distribution of salt-affected soils (SAS) for India and the world is essential for planning and implementing reclamation programs in a timely and cost-effective manner for sustained crop production. The national extent of SAS for India over the last four decades was assessed by conventional and remote ...

  • Spatial and temporal patterns of remotely-sensed and field-measured rainfall in southern California

    Quantification of spatial and temporal patterns of rainfall is an important step toward developing regional hydrological models. However, traditionally used rain gauge data are sparse and do not always provide adequate spatial representation of rainfall. In this study, we evaluated the daily 1-degree resolution remotely-sensed atmospheric precipitation data provided by Global Precipitation ...

  • Remote sensing of land degradation: experiences from Latin America and the Caribbean

    Received for publication April 6, 2009. Land degradation caused by deforestation, overgrazing, and inappropriate irrigation practices affects about 16% of Latin America and the Caribbean (LAC). This paper addresses issues related to the application of remote sensing technologies for the identification and mapping of land degradation features, with special attention to the LAC region. The ...

  • Radar remote sensing of wind-driven land degradation processes in northeastern Patagonia

    Received for publication February 27, 2009. Wind-driven land degradation negatively impacts on rangeland production and infrastructure in the Valdes Peninsula, northeastern Patagonia. The Valdes Peninsula has the most noticeable dunefields of the Patagonian drylands. Wind erosion has been assessed at different scales in this region, but often with limited data. In general, terrain features caused ...

  • Agricultural biomass monitoring on watersheds based on remotely sensed data

    There is a close quality relationship between the harmful levels of all three drought indicator groups (meteorological, hydrological and agricultural). However, the numerical scale of the relationships between them is unclear and the conversion of indicators is unsolved. Different areas or an area with different forms of drought cannot be compared. For example, from the evaluation of ...

  • Assessing and monitoring agroenvironmental determinants of recreational freshwater quality using remote sensing

    Diverse fecal and nonfecal bacterial contamination and nutrient sources (e.g. agriculture, human activities and wildlife) represent a considerable non-point source load entering natural recreational waters which may adversely affect water quality. Monitoring of natural recreational water microbial quality is most often based mainly on testing a set of microbiological indicators. The cost and ...

  • Classification of remote sensing images from urban areas based on fuzzy system

    The problem of classification of high-resolution remotely sensed images from urban areas is addressed. This work proposed a new method based on fuzzy system to recognise different areas in a remote sensing image. Previous studies have shown the interest of exploiting the local geometrical information of each pixel to improve the classification. This is performed using the Derivative ...
