Building a production-grade land information system for a state geographic information agency — every parcel, land file, owner, and document behind one map.
A state geographic information agency needed to move land administration off paper files and fragmented records. Answering a basic question — who holds this parcel, under what documents, with what history? — meant physically retrieving files.
Parcel maps, ownership records, and documents lived in separate silos, making transactions slow, disputes hard to resolve, and revenue leakage invisible.
The cadastral fabric published as live map services; clicking any parcel opens its complete record.
A one-to-one digital land file per parcel: current and historical ownership, deeds, certificates, and attached documents.
A PostGIS spatial database with dedicated schemas for cadastre, land files, documents, and workflow — built for scale.
A documented REST API over every entity, so payment systems, registries, and e-government services can integrate rather than re-digitize.
Multi-step cadastral processes — registration, transfer, subdivision — modeled in the system rather than around it.
