| Abstract | With the huge amounts of spatial data collected everyday, MapReduce frameworks, such as Hadoop, have become a common choice to analyze big spatial data for scientists and people from industry. Users prefer to use high level languages, such as Pig Latin, to deal with Hadoop for simplicity. Unfortunately, these languages are designed for primitive non-spatial data and have no support for spatial data types or functions. This demonstration presents Pigeon, a spatial extension to Pig which provides spatial functionality in Pig. Pigeon is implemented through user defined functions (UDFs) making it easy to use and compatible with all recent versions of Pig. This also allows it to integrate smoothly with existing non-spatial functions and operations such as Filter, Join and Group By. Pigeon is compatible with the Open Geospatial Consortium (OGC) standard which makes it easy to learn and use for users who are familiar with existing OGC-compliant tools such as PostGIS. This demonstrations shows to audience how to work with Pigeon through some interesting applications running on large scale real datasets extracted from OpenStreetMap. |

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.
