The Local Government Information Model incorporates five key elements from the Building Interior Space Data Model (BISDM) to help you organize these building features on a campus.

• Building (the building footprint polygon)
• BuildingFloor (a polygon for each floor in a building)
• BuildingFloorplanLine (a line feature representing walls, stairs, columns, and so on)
• BuildingFloorSection (also called wings or subdivisions of a BuildingFloor)
• BuildingInteriorSpace (offices, restrooms, and so on)

This workflow will outline the necessary steps to create building features manually by georeferencing your scanned building floor plan; sketching in lines to represent walls, doors, and windows; and creating your interior space polygons from these lines.

To add interior features manually, complete the following steps:

1. Georeference the raster floor plan image. The Campus Editing map document contains a georeferenced floor plan image for a small building as an example.
2. Start an edit session.
3. For each floor in your building, create the BuildingFloor polygon and provide the appropriate attributes (FLOORID, BUILDINGKEY, FLOOR, BASEELEV, and so on).
4. Use the georeferenced image to trace BuildingFloorplanLine features such as the following:
   • Exterior walls
   • Interior walls
   • Doors
   • Windows
5. Save your edits.
6. Open the Feature To Polygon tool from the Features toolset in the Data Management toolbox, and add your building floor plan lines.
7. In the Catalog window, use the Simple Data Loader to load these polygons into the MapsandGeodatabase\LocalGovernment.gdb\FacilitiesStreets\BuildingInteriorSpace feature class.
8. Add the features from the MapsandGeodatabase\LocalGovernment.gdb\FacilitiesStreets\BuildingInteriorSpace feature class.
9. Use definition queries to help populate the attributes for your spaces, primarily the (unique) SPACEID and SPACETYPE values.
10. Define the building footprint by creating a Building polygon with the appropriate attributes.
11. Optionally, update the building footprints in your cached campus basemap.
