Topographic and other features mapped during land surveys in oil and gas exploration and production are currently collected in a variety of CAD, GIS, ASCII and other file types and formats. This leads to difficulties in the management of the survey data, including integration of such data within corporate databases and data management systems, and in the external exchange and sharing of the data with partners, regulators, and other parties.

It provides a consistent approach for spatial visualization, data sharing and integration, through predefined entities and attributes. LSDM is intended to complement the existing IOGP Seabed Survey Data Model (SSDM).
Version 1 of the LSDM package will unpack itself into the following structure:
