Implementing LADM Using the Parcel Fabric as a Well Architected System

Resumo

The Parcel Fabric represents a conformant implementation of the Land Administration Domain Model (LADM), as defined by ISO 19152:2012. Since its release in 2019, it has been adopted by hundreds of organizations globally, supporting a range of deployment models including single-user file geodatabases, enterprise environments with concurrent editing, and an upcoming Software as a Service (SaaS) offering via ArcGIS Online. This paper introduces the concept of a "well-architected system" in the context of cadastral implementations, structured around six foundational pillars: automation, integration, observability, performance and scalability, reliability, and security. These pillars are essential for the successful operationalization of LADM in production environments. Additionally, the paper explores how the Parcel Fabric information model extends beyond the core LADM specification to incorporate advanced capabilities such as parcel lineage, historic parcels, editor tracking, built-in configurable quality rules, and support for repeatable workflows using tasks.
