Geographic Information System (GIS) - (1) A system or process that electronically captures, stores, analyzes, manages, and presents data linked to location, primarily in map form. Layers of illustrative information can be selected and displayed such as aerial photography, topographic maps, flood maps, streets and roads, earthquake information, zoning overlays, political boundaries, and other forms of geographically referenced data. (2) A collection of computer hardware, software, and geographic data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. GIS technology integrates common database operations such as query and statistical analysis with the unique visualization and geographical analysis benefits offered by maps. (ESRI) (3) A computer system capable of assembling, storing, manipulating, and displaying geographically referenced information, i.e., data identified according to their locations. Practitioners also regard the total GIS as including operating personnel and the data that go into the system. (USGS) (4) An integrated system of computer hardware, software, and trained personnel linking topographic, demographic, utility, facility, image, and other resource data that is geographically referenced.

May have cabinets or storage shelves, and electric garage door opener.

Gross Area Square Feet - The sum square feet of the BAS (base) square feet plus each sub-area square footage.

An area which is of lower quality than GRF, e.g., unfinished ceiling (beams or rafters exposed), minimal or no electrical outlets, concrete or other hard packed parking pad or floor, typically will not have insulation. Typically, walls are open stud or unfinished block.
