A Modified Bare Soil Index to Identify Bare Land Features during Agricultural Fallow-Period in Southeast Asia Using Landsat 8

A New Bare-soil Index for Rapid Mapping Developing Areas Using Landsat 8 Data

One of the most basic classification tasks is to distinguish bare-soil areas from urban region. Bare-soil plays an important role in the ecosystem. It could be the reason of dust storms and the indicator of urban expansion. It is also important to monitor the bare-soil areas, but there was no good idea to automatically extraction bare-soil areas using existing method. In this work, a new barene...

Mapping soil salinity using Landsat 8 images for land evaluation: A Case Study of Saveh

Introduction: As a valuable asset that play a key role in the environment, natural resources, and the production of agricultural products, soil provided an appropriate ground for plant growth and vegetation development. Therefore, any disregard to the preservation of such a valuable capital may result in food shortages, soil erosion, and degradation of natural resources. From among different i...

Methyl Bromide Emissions from Agricultural Fields: Bare-Soil, Deep Injection

Use of TerraSAR-X data to retrieve soil moisture over bare soils agricultural fields

The retrieval of the bare soil moisture content from TerraSAR-X data is discussed using empirical approaches. Two cases were evaluated: (1) one image at low or high incidence angle, (2) two images, one at low incidence and one at high incidence. This study shows in using three databases collected between 2008 and 2010 over two study sites in France (Orgeval and Villamblain) that TerraSAR-X is a...

Retrieval Bare-soil Moisture Using L-band Sar

This paper reports a study of algorithm development and testing for soil moisture retrieval for bare fields using L-band SAR imagery. First-order surface scattering models predict that the co-polarization ratio is sensitive to soil moisture but not to surface roughness. Our previous study indicated that the measurement of (Jvv / (Jhh at L-band is proportional to soil moisture. In this study, th...
