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 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.
The IOGP Land Survey Data Model was established to define a standard GIS data model for land surveys, addressing the need for a common structure for storing, managing, and visualizing onshore survey data. 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).
