From tax maps and property records to a working parcel database.

Tax declarations, parcel identifiers, old tax maps, cadastral sheets, and field notes often sit in different places. Before a map becomes useful, staff need to know which records refer to the same property and where the source is uncertain.

SPARTA is scoped around that work. An implementation may include scanning and digitizing source maps, populating a parcel database, matching records, mapping parcels, and flagging exceptions for review. The aim is an office that can use and update the information after the initial project.

Digitize the source, reconcile identifiers, map the parcel, validate uncertain cases, operate with the records, and maintain changes. The sequence is a working model, not a promise that every LGU begins at the same stage.

Parcel divisions, consolidations, corrections, and new assessments need a clear route through the office. Staff should be able to see the source of a geometry, who reviewed it, and what still needs field or document validation.

The Real Property Valuation and Assessment Reform Act encourages stronger property information and digital workflows. A usable map and reconciled parcel records can support preparation, but software alone does not establish compliance with valuation standards or implementing rules.

We start with the Assessor's Office process and the available records, then discuss what digitization, validation, and ongoing support the LGU actually needs.
