- One of the earliest known geological maps is a geologic map of England constructed by William Smith in 1815. Topographic and geologic maps are basic tools used for the management and development of the earth's resources. Topographic maps represent on paper the earth's surface and its various landforms. Geologic maps show the distribution of the rocks that underlie the landforms and provide a view of the earth's surface to a depth of several thousand feet.
