maps are detailed city plans, usually at scales of 50 or 100 feet
to an inch. They show individual building "footprints,"
complete with construction details, such as building material
(brick, adobe, frame, etc.), height (of larger buildings), number
of stories, location of doors, windows, chimneys and elevators,
use of structure (dwelling, outhouse, hotel, church, etc.), street
address, and occasionally the ethnicity of the occupants. Other
features shown include lot lines, street widths, water pipes,
hydrants and cisterns, and fire-fighting facilities.
