| Abstract | Locust infestations of semiarid areas are preceded by well defined soil moisture conditions. Therefore the potential of outbreaks can be partially predicted by accurate mapping of soil moisture on the field-scale (/spl sim/100 m). In this manner, Radarsat International has run a successful locust outbreak prediction campaign in Kazakhstan (LIMIS). This was based on Radarsat-1 backscatter images combined with simultaneous soil moisture ground truth. Although, as shown by LIMIS, soil moisture maps can be successfully derived from RADARSAT-1 imagery using high quality ground measurements, this method has disadvantages. The main problem is the high cost and difficulty associated with collecting sufficient ground measurements. To overcome this problem, soil moisture maps can be derived without the use of ground measurements from multiple RADARSAT-1 images, each with a different incidence angle. This work presents encouraging research results towards an automated ground-measurement free system based on multi-angle SAR data inversion. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
