CAMA Core: Maryland Property Appraisal Characteristics by Parcel

Yearly property assessment data from the State of Maryland Department of Assessments and Taxation.

Other CAMA themes for Building, Building Subareas, and Land can be joined to this core record.

Strengths

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
