| Abstract | Crop physiology analysis and growth monitoring are of great importance for precision agriculture. Remote sensing technology supplies us with more selections and available spaces in this dynamic change study by producing images of different spatial, different spectral and different temporal resolutions. Especially, the remote sensing data of high spectral and high temporal resolution will play a key role in land cover studies at national, regional and global scales. In this paper, a new effective data structure conception, temporal index image cube (MIIC) is proposed in aid of the parameterization of the multi-dimension spectral curve. MIIC is proved very useful for the dynamic analysis of vegetation. Based on multi-temporal meteorological satellite data and multi-temporal ground spectral measurements, the temporal characteristics of different vegetation physiological parameters are contrasted and analyzed from the temporal index image cube. It turned out, each crop has its differentiated temporal index curve. Based on this multi-temporal index image cube, the classification and identification on various crops is very practicable. Some spectral indices perform fairly well on monitoring the growth situation of crops. But more efforts still should be made to develop new effective and general spectral indices, which will be more sensible to land cover types and the growth situation, moreover, it will screen the effects of atmosphere and background to a large extent. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
