Real Estate Mapping and Cadastral Modernization Initiative, Phase I

The Navy expressed a concern in the lack of unified and standardized protocols for the management of its important cadastral records. Specifically, NAVFAC Southeast region was challenged with real estate maps that were inconsistent, inaccurate, not in a modern formats, and muniments were not accessible digitally. To remedy this, HDR began a pilot program for NAVFAC Southeast that developed into the Cadastral Modernization Initiative (CMI).

CMI is an overarching approach to the development, tracking, survey, mapping, integration, distribution and storage of authoritative and accurate real estate records using GIS to leverage technology geographically and provide system-wide accessibility in an on-demand web map viewer (GRX). The startup phase of the CMI audited and analyzed property muniment information for over 100 sites, tracked discrepancies geographically, spatially referenced CAD Real Estate Summary Maps (RESMs) with high-precision survey and rubbersheet techniques, and converted static CAD drawings and iNFADS data to SDSFIE-compliant geodatabase feature classes. Site summary packets were prepared for each site that include site survey notes/data, a discrepancy database and map layer, applicable photographs, and an overall site grade. These grades represent the degree of risk associated with the accuracy of the site records, allowing the Navy to prioritize its funding toward those sites with the greatest need for costly boundary surveys or other actions. Over half of the project effort involved signed/sealed land surveys.

Phase I, as the pilot was called, also included development of an interactive Standard Operating Procedure Guide that optimizes the process of handling real estate actions as they travel through the Asset Management Business Line, from property acquisition to disposal, and includes technical guidance for GIS conversion and creation of a GeoRESM. During this process, HDR developed a data dictionary that has since been considered the prime basis for the Navy adaptation to SDSFIE version 3.0. Phase II, currently underway under a separate task order, provides a Needs Assessment and future plan, additional sites, charrettes for sites completed in Phase I, and increased training and business process development.
