| Abstract | Laser altimeter systems provide an accurate measurement of canopy height, the vertical structure of vegetation and the aboveground biomass (AGB). Airborne discrete return LiDAR (Light Detection and Ranging) was used operationally in many cases and some regions; spaceborne large footprint LiDAR (ICESat GLAS) has acquired over 250 million LiDAR observations over forest regions globally. The ICESat GLAS data have been used successfully for forest height and biomass in various sites. To estimate aboveground forest biomass in the Southwest of China, products from EOS MODIS and ENVISAT MERIS were used to expand the estimation from GLAS data. Airborne LiDAR data were collected along GLAS orbit to estimate forest height and biomass for each GLAS footprint after training with 81 field measured plots. The $R^{2}$ are 0.68 and 0.91 for field measured biomass and mean height estimation using airborne LiDAR data. Then the aboveground biomass was estimated from ICESat GLAS data using the equation trained by field data $(R^{2}$ = 0.47, n=185). EOS MODIS Vegetation Continuous Fields (VCF) product, enhanced vegetation index (EVI) product and ENVISAT MERIS Regional Land Cover product were used to generate 175 forest classes, which included five forest canopy density classes, five vegetation index classes, and seven forest cover types. Then we combined forest aboveground biomass derived from GLAS pulses footprint with 175 forest classes to generate a continuous aboveground forest biomass map of study area. Forest aboveground biomass was minimal at 43 Mg/ha, maximal at 133 Mg/ha, averaged at 78.9 Mg/ha in the study area. The results of predicted aboveground biomass were in agreement on the amount and distribution after comparison with reference data, which showed that the predict model for GLAS successfully captured the distribution of aboveground biomass. |

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.
