Started in 1991 as a small firm, DSM has grown to be a global organization with over 1000 employees. Over the years, the group has grown consistently and carved a niche for itself to be one of the high quality, most cost effective service providers in the Geo-spatial Data Services and Engineering Data Services domain.

Since 1991, DSM has been focusing on delivering high quality services at affordable cost. This earned the group a high reputation among the clients not just in India, but also across the globe.

DSM has development centers in Chennai & Tiruchirapalli in India and offices in Chennai and Scotland. Backed by professional management, an efficient team of specialists, best business and HR practices, DSM has a solid track record of delivering value added services to the clients.

DSM's growth curve has been steep and the credentials high. The group's incredible performance can be illustrated by the fact that DSM went on to acquire the mapping business of Survey & Development Services Ltd (SDS), Scotland's first surveying and mapping company and one of the UK's foremost companies in the field of Geo-Spatial Data Services, working internationally for major clients such as National and local government, public utilities, international project management consultants, consulting engineers, architects, construction contractors and others.

The acquisition has given DSM the global reach and a formidable combination of European expertise and Indian costing. Today, DSM is a prominent player in Geospatial Engineering services.
