ID

Unique identifier for each footprint polygon.

No description available for this field.

Name (identifier)	id
Type	integer
Sample

ORIENT8

Angle of footprint polygon in degrees. For example, a footprint with an ORIENT8 value of 0.2 will be .2 degrees from North.

No description available for this field.

Name (identifier)	orient8
Type	decimal
Sample

BLDGID

A value shared by all polygons that make up an individual building. For example, an apartment building could be composed of a polygon for its podium, another for the tower, and one for the mechanical penthouse. Each of these polygons will have a unique ID, but will share a common BLDGID attribute such as “58832”.

No description available for this field.

Name (identifier)	bldgid
Type	integer
Sample

TOPELEV_M
