	Building Footprints - represents building "footprints" or outline of outermost perimeter of a contiguous building. This data set was developed by USI Hawaii using aerial photography captured in the spring and summer of 2005.

Metadata

ATTRIBUTES:

COLUMN NAME	DESCRIPTION	SAMPLE
bldg_name	the name of a building (USI Hawaii)
tmk	tax map key
height	building height in feet calculated from the 3D building model
yearblt	year building complete from facilities table
floors	number of floors above ground from facilities table
floorarea	floor area from facilities table
type	building type from facilities table

NOTES:

These building footprints were developed using hi resolution aerial photography and a software program called Nverse Photo. The Nverse Photo building compounds are exported into 2D and 3D shapes. Typically, unwanted features are included that appear fine in a 3D model but are not needed in the footprint. Visual checks are made of the data and the shapes to ensure that information is ported correctly. Per this document, the data structure is modified, tables are populated and indexed. The Shapes are then imported into a geo-database and integrated with multi-patch, 2D polygon and centroid feature classes. A relationship class is defined between the multi-patch and 2D polygon feature classes. A final visual check is made of both data and objects before transmittal to the City.
