  • 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 ...

  • Optical Remote Sensing in the United States

    Recent studies that involve the use of optical remote sensing (ORS) techniques to measure gaseous and particulate pollutants have rekindled interest among environmental researchers and regulators in this decades-old technology. This article describes some of the key research and development projects that are helping restore ORS-based methods to the list of currently available emissions ...

  • Salinity monitoring in western Australia using remotely sensed and other spatial data

    Received for publication January 27, 2009. The southwest of Western Australia is affected by dryland salinity that results in the loss of previously productive agricultural land, damage to buildings, roads, and other infrastructure, decline in pockets of remnant vegetation and biodiversity, and reduction in water quality. Accurate information on the location and rate of change of the extent of ...

  • 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 ...

  • 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 ...

  • 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, ...

  • Predictions in a data-sparse region using a regionalized grid-based hydrologic model driven by remotely sensed data

    The goal of this study was to assess the feasibility of using Tropical Rainfall Measuring Mission (TRMM) and Moderate Resolution Imaging Spectroradiometer (MODIS) products to drive a mesoscale hydrologic model (mHM) in a poorly gauged basin. Other remotely sensed products such as LandSat and Shuttle Radar Topography Mission (SRTM) were also used to complement the local geoinformation. For this ...

  • Evaluation of remotely sensed snow cover product in Central Asia

    Central Asian countries depend highly on water resources from snow and glacier melt, which has to be studied thoroughly to estimate water availability. However, the observation network in Central Asia is poor to carry out such studies in detail. Observations from space using remote sensing techniques might fill this observation gap, which needs to be validated. Therefore, this study evaluates ...

  • Remote sensing models using Landsat satellite data to monitor algal blooms in Lake Champlain

    Lake Champlain is significantly impaired by excess phosphorus loading, requiring frequent lake-wide monitoring for eutrophic conditions and algal blooms. Satellite remote sensing provides regular, synoptic coverage of algal production over large areas with better spatial and temporal resolution compared with in situ monitoring. This study developed two algal production models using Landsat ...

  • Digital soil-class mapping from proximal and remotely sensed data at the field level

    Effective agronomic management at the field level requires an understanding of the spatial distribution of soil because edaphological processes are a function of interrelationships among the physical and chemical properties. In precision agriculture, these interrelationships need to be considered to create soil management classes. In order to identify management classes, the age-old questions ...

  • 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 ...

  • Portable Remotely Operated Drill (PROD): Hydrocarbon Sensing System

    Proven Technology Benthic’s prototype Hydrocarbon Sensing System (HSS) analyses drill returns for the presence of hydrocarbons as they pass through PROD before being vented on the seafloor. The System, in its present form, includes two hydrocarbon sensors in line with the drill returns path. Drill returns, composed of seawater drawn from above PROD and pumped down the drill ...

  • 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 ...

  • How Remote Sensing Can Save Time & Money - Roads & Bridges

    A 2014, Department of Transportation report finds that to maintain the condition of U.S. highways and bridges at 2010 levels through the year 2030, between $65.3 billion and $86.3 billion per year would be required. A suburb in the greater St. Louis area has recently been ...

  • Application of thermal remote sensing to delineate groundwater discharge zones

    The paper explores whether thermal anomalies at the surface identified by remote sensing allow for the delineation of groundwater discharge zones. The methodology is based on the principle that in shallow groundwater systems, upward fluxes of deep groundwater discharge reduces seasonal temperature variation in layers close to and at the surface. Thermal anomalies were identified by Landsat data ...

  • Digital Change Detection Using Remotely Sensed Data for Monitoring Green Space Destruction in Tabriz

    Being very dynamic, natural and artificial land features are changing somewhat rapidly in over lifetime. It is important that such changes be inventoried accurately so that the physical and human processes at work can be more fully understood. Change detection is a technique used in remote sensing to determine the changes in a particular object of study between two or more time ...
