Cadastral mapping at Sidwell is performed through a comprehensive network of computer workstations, at which technicians perform map construction operations to create land information management systems.
Sidwell has mapped over 8 million parcels, and has 6 IAAO-Certified Cadastral Mapping Specialists on Staff
The cadastral or parcel mapping process begins with extensive research drawing on source documents, which might include tax records, legal descriptions, subdivision plats, surveys or deeds. Geographic information is compiled and reconciled against precision aerial photography, and parcel identification numbers applied. Quality control is stressed throughout the database development process.
Cadastral mapping can be overlaid on digital orthophotography or viewed in combination with topographic or planimetric mapping to provide further information in a geographic information system environment. Sidwell also offers cadastral map maintenance services to clients who find outsourcing their map maintenance to be a sensible alternative to maintaining their own map data.
