1. Microwave and Optical Remote Sensing | Chalmers The division consists of three research groups with the goal to provide and interpret global datasets relevant to current and future environmental problems. Optical remote sensing in VISNIR and SWIR wavelengths is a good source of information for soil mapping and monitoring, ameliorating the cost and effort needed to have accurate and up-to-date soil maps at different spatial scales. Optical and Microwave Remote Sensing for Crop Monitoring in Mexico J. Soria-Ruiz. H. McNairn Agri-Food Canada Beyond Diagnostics: Insights and Recommendations from Remote Sensing Workshop CIMMyT.

As described in Chapter 2, the microwave portion of the spectrum covers the range from approximately 1cm to 1m in wavelength. In this study, optical and microwave remote sensing data were used in combination for crop growth monitoring. Characteristics of radar remote sensing Dr. A. Bhattacharya 6 Advantages compared to optical remote sensing All weather capability (small sensitivity of clouds, light rain) Day and night operation (independence of sun illumination) No effects of atmospheric constituents (multitemporal analysis) Sensitivity to dielectric properties (water content , biomass, ice) The most significant difference in characterizing remote sensing image … The continuous EM spectrum also includes the visible and IR energy that is the basis of Optical Remote Sensing. A simple reflectance model was used for estimating leaf area index (LAI) from optical data, and a simple backscatter model was used for estimating LAI from radar data. The optical remote sensing uses the visible spectrum wavelength range (~400–700nm) whereas microwave remote sensing uses the microwave wavelength range of the electro magnetic spectrum, which is further divided into three parts like near infrared, far infrared and middle IR. Microwave sensing encompasses both active and passive forms of remote sensing. Microwave energy is just one form of Electromagnetic (EM) radiation. Optical and Infrared Remote Sensing In Optical Remote Sensing, optical sensors detect solar radiation reflected or scattered from the earth, forming images resembling photographs taken by a camera high up in space. Y. Fernández-Ordóñez Colegio de Postgraduados. National Institute of Forestry Agriculture and Livestock Research. Imaging With Microwaves. This goal will be achieved using complex mathematical models of both the measurement techniques and the earth-atmosphere systems. 8.
