CONSENT INDIAN RIVER COUNTY, FLORIDA MEMORANDUM ? TO: Jason E. Brown, County Administrator THROUGH: Dori Roy, Assistant to County Administratda FROM: Will Rice, Manager, GIS Department �. DATE: November 7, 2016 SUBJECT: 2017.Oblique Aerial Imagery Acquisition Project DESCRIPTION AND CONDITIONS Aerial photographs are used by County staff on a daily basis to provide information on the presence or absence of natural and man-made features and the condition of these features. For the past decade, high resolution vertical orthoimagery has been used by staff in conjunction with Geographic Information Systems (GIS) software for both photo interpretive and planimetric mapping tasks. More recently, a newer type of aerial imagery, oblique aerial imagery, has proved valuable in providing additional information and detail not available in the traditional vertical aerial imagery. Oblique aerial imagery, aerial photographs taken with the camera axis at a side angle, provides side and profile views of features. These oblique or side views frequently provide the additional information needed to visually identify a feature. Also, objects that are not visible in vertical aerial imagery can often be detected and identified using oblique imagery. For example, houses or other structures that are obscured by heavy tree canopy in vertical imagery can often be detected and identified using oblique aerial images. Pictometry International Corporation is a firm that specializes in acquiring high resolution oblique aerial imagery. Pictometry oblique aerial imagery provides the "Birds Eye View" aerial imagery found on the Microsoft Bing website. The Counties in Florida Pictometry currently contracts with include Brevard, St. Lucie, Broward, Palm Beach, and Okeechobee County Property Appraisers. Indian River County has previously contracted with Pictometry in 2011, 2013, 2015, and 2016. Staff is proposing a three year, multi-year contract with Pictometry to .acquire new high resolution oblique and vertical aerial imagery during the three time periods of January 2017, January 2018, and January 2019. The area. of coverage for each aerial imagery flight is 285 square miles and the specific limits of the project are shown in Attachment 1. Each area in the project area would be imaged in 5 different directions, north, south, east, and west, and a vertical view at approximately a 3" ground resolution. Staff is proposing the three year, multi-year contract with Pictometry because of the 15% discount Pictometry is offering with the three year contract. The contract includes a "Non -Appropriation" clause which allows the contract to be suspended for subsequent projects if in subsequent years funding is not approved for the contract. Pagel of 2 169
