Abstract

Maritime Infrastructure: Boundary and Cadastre Development Utilizing GIS
Track: Charting and Data Collecting
Authors: Douglas Vandegraft, Jamieson Murphy

Developing a marine cadastre can be a daunting exercise. This presentation will focus on a GIS vision for supporting the complexities of establishing and managing offshore boundaries and lease areas. The Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) is responsible for managing the offshore leasing program for the Federal Government, and has contracted with ESRI, Inc. for development of a special suite of geospatial tools. Topics of discussion include building a survey-aware cadastral network, fixed and ambulatory boundaries, building reproducible solutions and supporting planar, geodesic and loxodrome calculations. Applications range from the creation and management of Official Protraction Diagrams, lease blocks, block sub-areas, baselines and boundaries with the goal of expediting workflows, improving knowledge transfer, and addressing new renewable energy initiatives by the Federal Government.
