Maryland Historical Trust

Architectural Survey Data Analysis Project

The Architectural Survey Data Analysis Project is a multi-year effort by the Maryland Historical Trust (MHT) to review and analyze Maryland’s architectural survey data. This work helps: 

  • Identify gaps in survey coverage by county, theme, and building type.
  • Expand searchable fields in Medusa, the state’s cultural resource information system.
  • Support better research, planning, and preservation decisions across Maryland. 

About the project  

MHT’s team is: 

  1. Reviewing existing records: Examining Maryland Inventory of Historic Properties forms for standing structures (for example, historic buildings as well as historic structures such as bridges and lighthouses), National Register of Historic Places nominations, maps, and photographs. 

  2. Identifying gaps: Finding where certain building types, themes, or regions are under-surveyed and making recommendations for new survey work.
  3. Assessing data quality: Checking how complete each record is and whether new surveys are needed.
  4. Improving access to research data: Adding searchable fields in Medusa so users can locate and compare resources across the state more easily (for example, “all Greek Revival churches from the 1850s in a county”).    

As the project moves forward, MHT will continue to produce: 

  • Individual reports, organized by county, that show where survey and documentation gaps exist. These reports help local governments and planners make informed development and preservation decisions and are available by request. Completed reports include: Cecil, Charles, Frederick, Harford, Kent, Queen Anne’s, Somerset, Washington, Wicomico, and Worcester counties.
  • Statewide recommendations for future survey and research priorities to guide preservation professionals working on historic buildings and districts.
