A. The following requirements provide for digital stereo compilation of aerial photography and preparation of geographic base maps in accordance with these standards. Geographic base maps shall consist of either planimetric maps or topographic maps which are generally defined and described as follows:

1. planimetric maps depict only the horizontal positions for features represented, such as rivers, lakes, transportation routes, woodlands, farms, railroads, building outlines, and other photo identifiable features;

2. topographic maps depict both the horizontal and vertical positions of features represented, and are distinguished from planimetric maps by the addition of vertical relief data in measurable form such as contour lines, spot elevations, and related vertical information.

B. Geographic base maps conforming to either planimetric or topographic requirements, at the discretion of the responsible contracting authority, shall be prepared to cover the entire limits of the project area as depicted on the Project Contract Map. All required planimetric features and vertical features, if required, shall be included on the geographic base map. These features shall be digitized, coded, assembled and stored on acceptable computer transfer media from which this data can be retrieved, viewed and/or plotted on the Geographic Information System in use or selected by the responsible contracting authority and/or other participants and users.

AUTHORITY NOTE: Promulgated in accordance with R.S. 50:171.
