Land Survey Data Model
LSDM is an industry standard template for operators to maintain land survey data, mainly acquired for the oil and gas industry. It is currently available in version 1 released in December 2022.
The model enables the storage of key geospatial and non-geospatial descriptive and feature-specific elements of the following land-based survey activities:
- Design, engineering and construction surveys of infrastructure and facilities including proposed routes, as-found, as-left, as-installed, and as-built positions; depth of burial; general/detail layout surveys etc. – for company or third-party facilities which may overlap or impact on E&P infrastructure (e.g., those owned or operated by utility companies)
- Land and topographic surveys, including elevation (contours, spot heights, relief shading, terrain modelling, etc.), natural and man-made features, explosive remnants of war (ERW), archaeological sites, and underground services surveys etc.
- Geodetic and survey control network surveys, including coverage, line of sight, monumentation, etc.
- Land survey measurements, survey line plans, and similar documentation for UAV/LiDAR operations or similar (planned and as-executed)
- Vegetation and land use surveys
- Imagery: from satellite, UAV, and crewed survey flights (satellite imagery, LiDAR, aerial photography, etc.)
- Right of Way (ROW) surveys and surveillance (ROW anomalies and observations): pipeline route surveys, pipeline and facility UAV inspection, access road surveys, etc.
- Administrative boundaries and cultural information (roads, railways, rivers, habitation, etc.)
- Geophysical/seismic, exploration and reconnaissance, geohazard, shallow and intermediate geology surveys
- Geotechnical soil investigations
- Environmental baseline and monitoring surveys
- Infrastructure condition and subsidence monitoring surveys
