Building Footprints

	CCH GIS Data Dictionary
	Building Footprints - represents building “footprints” or outermost perimeter of a contiguous building. This data set was developed by Hi-Tech Urban Solutions (was USI Hawaii) using aerial photography captured in the spring and summer of 2005.

Metadata

ATTRIBUTES:

COLUMN	DESCRIPTION
bldg_name	the name of a building
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.
