The RCAHMS collects, records and interprets information on the architectural, industrial, archaeological and maritime heritage of Scotland. A series of Guides for Researchers at the website explains the work of the commission and how to use the various services. For an overview of the collections see the section What We Hold.

The RCAHMS databases are the gateway into the online, searchable record of the collections and survey work, providing access to descriptions of drawings, photographs, negatives and manuscripts relating to Scotland's archaeology, buildings and maritime heritage. The databases comprise the following:

Canmore: Canmore provides searchable, map-based information on buildings, ancient monuments and archaeological sites throughout Scotland.
The National Collection of Aerial Photography: Aerial imagery collections.
Scran: Online image archive.
Scotlands Places: Information relating to places throughout Scotland including maps and plans of counties, cities, towns, villages, farms, roads, canals, harbours, churches, schools, public buildings, private houses, mines and quarries.
Buildings at Risk Register: The online register of Scottish buildings of architectural or historic merit considered to be at risk or under threat.
HLAmap: Provides map-based analysis of past and present-day land use throughout Scotland, creating a digital map of the historic landscape of Scotland.
PASTMAP: PASTMAP brings together information from RCAHMS, Historic Scotland and Local Authority Sites and Monuments Records into one searchable system.
