It is the intent of the legislature to establish a coordinated system of state base maps to assist all levels of government to more effectively provide the information to meet their responsibilities for resource planning and management.

It is further the legislature's intent to eliminate duplication, to insure compatibility, and to create coordination through a uniform base which all agencies will use.

It is in the interest of all citizens in the state of Washington that a state base mapping system be established to make essential base maps available at cost to all users, both public and private.

The department of natural resources shall establish and maintain a state base mapping system. The standards for the state base mapping system shall be:

All features and symbols added to the quadrangle separates shall meet as nearly as is practical national map accuracy standards and specifications as defined by the United States geological survey for their fifteen minute and seven and one-half minute quadrangle map separates.

Each quadrangle shall be revised by the department of natural resources as necessary to reflect current conditions.

Any state agency purchasing or acquiring United States geological survey quadrangle map separates shall do so through the department of natural resources.
