INDIAN RIVER COUNTY, FLORIDA <br />MEMORANDUM <br />TO: Joseph A. Baird, County Administrator <br />THROUGH: Dori Roy, Assistant to County Administra <br />FROM: Will Rice, Manager, GIS Department <br />DATE: November 7, 2014 <br />SUBJECT: 2015 Oblique Aerial Imagery Acquisition Project <br />DESCRIPTION AND CONDITIONS <br />Aerial photographs are used by County staff on a daily basis to provide information on the <br />presence or absence of natural and man-made features and the condition of these features. For <br />the past decade, high resolution vertical orthoimagery has been used by staff in conjunction with <br />Computer Aided Design (CAD) and Geographic Information Systems (GIS) software for both <br />photo interpretive and planimetric mapping tasks. More recently, a newer type of aerial imagery, <br />oblique aerial imagery, has proved valuable in providing additional information and detail not <br />available in the traditional vertical aerial imagery. <br />Oblique aerial imagery, aerial photographs taken with the camera axis at an angle, provides side <br />and profile views of features that are more familiar to the user as compared to the vertical view <br />provided by vertical aerial imagery. Also, objects that are not visible in vertical aerial imagery <br />can often be detected and identified using oblique imagery. For example, houses or other <br />structures that are obscured by heavy tree canopy in vertical imagery can often be detected and <br />identified using oblique aerial images. <br />Pictometry International Corporation is a firm that specializes in acquiring oblique aerial <br />imagery. Pictometry oblique aerial imagery provides the "Birds Eye View" aerial photographs <br />found on the Microsoft Bing website. The Counties in Florida Pictometry currently contracts <br />with include Brevard, St. Lucie, Broward, Palm Beach, and Okeechobee County Property <br />Appraisers. Indian River County has previously contracted with Pictometry in 2011 and 2013. <br />Staff proposes contracting with Pictometry in 2014 to acquire new oblique and vertical aerial <br />imagery for the eastern half of Indian River County during the first quarter of 2015. The area of <br />coverage for the proposed project is 291 square miles and the specific limits of the project are <br />shown in Attachment 1. Each area in the project area would be imaged in 5 different directions, <br />north, south, east, and west, and a vertical view at approximately a 3" ground resolution. <br />The specific deliverables for the project are listed in Section A. Imagery deliverables for the <br />project include a digital image library containing the oblique aerial imagery and a single <br />seamless image mosaic created from the vertical imagery. Pictometry has specialized software <br />for viewing and working with the oblique and vertical imagery. Pictometry's software <br />applications include their Electric Field Study (EFS) desktop software, ConnectExplorer web <br />applications, Connect Mobile applications for tablets and smartphones, and Pictometry's <br />Page 1 of 2 <br />43 <br />
