(PWT), under contract with LPWCD, obtained aerial <br />photographs and generated color digital orthophotos and a digital terrain model for the LHR site. <br />PWT flew the LHR site was flovm on February 23, 2002. Color stereo pair photographs, <br />together with ground survey control points, were used to generate a topographic map of the site <br />with 2-foot contour intervals (see Figure 1). <br /> <br />PWT delivered electronic and mylar copies of the LHR topographic mapping, as well as color <br />digital orthophotos. This base mapping was used for various tasks for the LHR Phase I <br /> <br />991-077.115 <br />May 2004 <br /> <br />Wright Water Engineers, Inc. <br /> <br />Page 5 <br />
