  • Completeness in land registration and efficiency in land-information services have emerged as global prerequisites to achieve sustainable development goals (SDG) and ease of doing business (EoDB). Land registration is a national priority for Indonesia, which aims to complete the process for all unregistered land parcels in the country and validate the quality of previously registered and certified land parcels before 2025. Efforts on this front uncovered the need for adopting mobile technology, including various data collection tools for surveyors and project contractors. Unfortunately, these tools present data standardization and data usability challenges, hindering efficient first titling and forensic titling, or title validation for imposing quality improvements. Data collection could be executed quickly and efficiently by aligning to Land Administration Domain Model (LADM) standards. This paper presents the design for and the test results of an LADM-compliant field data collector to help surveyors support first-titling and forensic-titling survey scenarios. The mobile application utilizes Open Geospatial Consortium (OGC) GeoPackage to access and locally store spatial and textual data retrieved from national cadastral databases. The mobile app allows surveyors to connect with external sensors including the Global Navigation Satellite System (GNSS) to accurately survey land. It employs a fingerprint reader for validating personal information via Bluetooth. Surveyors can map and edit data by applying drawing tools like snapping, splitting, and merging parcels. In addition to spatial data creation, this tool captures physical documents and records boundary validation digitally. This paper presents a field test for real field activities to validate old land titles.
