 | Building Footprints | Regional building footprints. Original buildings are constructed of multiple "polygons" representing the different building heights. All polygons making up a single building have the same "building ID" [Bldg_ID], which was used to dissolve the buildings into generalized building footprints. Attributes that apply to the entire building were retained. | Building | 04/22/19 03:39 PM |
 | Buildings | Regional buildings with building height and roof elevation information. Many buildings are constructed of multiple "polygons" representing the different building heights. All polygons making up a single building have the same "building ID" [Bldg_ID], which can be used to dissolve the buildings into generalized building footprints. | Building | 04/22/19 03:43 PM |
| | Demolition Permit Activity | Estimated Location of Demolition Permit Activity from the TRACS system. | Building | 11/25/15 09:38 AM |
 | Port of Portland Buildings | Polygons representing building footprints on or adjacent to Port of Portland property. Polygons were derived using a combination of hand digitizing based on 6" aerial photography or extracted from Port Engineering as-built drawings. Note that this dataset will be fully merged with City of Portland building data in 2014. | Building | 05/06/11 01:51 PM |
