Building Interior Space Data Model Group
The Building Interior Space Data Model Group (BISDM) Group is an independent committee, with members from both the private and public sectors, that shares information, ideas, and experiences about enhancing facilities management with GIS.
As a member, you'll be involved in the collaboration on the BISDM—a model you can use for representing and modeling facility interiors using ArcGIS.
The BISDM Group, together with Esri, built the Building Interior Space Data Model, which includes a logical and physical UML diagram that you can directly import to ArcGIS.
