With the emergence of technologies in mobile computing domain, people are able to access Internet and related services through small hand held devices such as mobile phones, smart phones and PDAs. Mobile devices are resource constraint as they have less memory and processing power. When such devices are used to make range queries on spatial database, the results retrieved by the query are huge number of tuples that can't be easily presented by hand held devices. This is because they have less communication bandwidth and energy. They can't show the results as it is. From this perspective, this paper presents a new way of representing a specified size of results that causes very less information loss.
