Topographic Surveying Services. The Consultant will prepare a suitable base drawing in CAD format from existing airport documentation and the following topographic survey services: • Obtain any records from the city or County of Riverside that pertain to the establishment of horizontal and vertical control for aerial topographic mapping derived from photogrammetric methods. • Conventional methods will be employed for the field work required to establish horizontal and vertical control and the setting of aerial control targets. Five (5) aerial targets will be required for this effort. • After completion of the manuscript copy of the photogrammetric map, Consultant will visit the airport to make sure all topographic features and physical culture have been adequately and accurately shown on the manuscript. • The final topographic map will span a width of approximately 1,600 feet (centered on the runway) by a length of approximately 6,000 feet.
