  In this paper, we present a methodology to automatically derive the
generalised representations of buildings at scales 1:25K, 1:50K, and to
delineate the urban area for 1:250K scale representation. These generalised
representations are derived from 1:10K scale. The automatic generalisation
processes are realised using the specific algorithms and the generalisation
models available in the CartAGen (CARTographic Agent GENeralisation) platform.
The CartAGen is an open source map generalisation platform developed by IGN
France. The proposed methodology in this paper is evaluated using the data
products available from the Ordnance Survey, UK, and the Survey of India,
India. This study investigates the applicability of the CartAGen platform for
generalising the data products which have been excluded from the investigations
by IGN France. This paper discusses the modifications required for such data
products.
