The EAO <br /> is conducted by photographing selected areas with aerial cameras. These cameras are <br /> able to detect conditions that are visible and invisible to the human eye. <br /> All conditions that fit pre-specified environmental criteria are photographed with a <br /> variety camera systems which include; visible range film, infrared 35mm slide film, and <br /> several hyperspectral bands such as chlorophyll a, carotene, water penetrating, and <br /> thermal, depending on the target. The collected data images are then analyzed to confirm <br /> and further investigate the observations made during the flight. A report is prepared <br /> presenting the findings of the EAO to the client. The report contains maps of each <br /> location recorded, a written documentation of the findings, and the image data. <br /> The benefit of the EAO is that a large area can be surveyed and data collected, <br /> quickly and inexpensively. <br /> EURASIAN WATER MILFOIL IDENTIFICATION <br /> Eurasian Water Milfoil and other types of vegetation can be <br /> mapped by an EAO using visible range film and hyperspectral <br /> cameras. The image on the left shows a lake that has <br /> Eurasian Water Milfoil. Other applications include wetland <br /> inventory and mapping, delineated and identified by type. <br /> VIOLATION/COMPLIANCE OVERFLIGHTS <br /> An EAO is an ideal tool to assist policy makers in checking <br /> for ordinance violations/compliance or best management <br /> practices associated with buildings, feedlots, building <br /> setbacks, gravel pits, conditional use permits, fill in wetlands <br /> and lakebed, hazardous waste areas, dumps, etc. A large area <br /> NOWLk.BW can be investigated in a short time, often revealing evidence <br /> unable to be seen at ground level. <br /> FEEDLOT AND OTHER INVENTORIES <br /> Farming operations can be quickly inventoried through the <br /> EAO providing information on location (GPS Coordinates <br /> and legal description), farming type (cattle, hay, row crops, <br /> etc.), and potential violations or environmental problems <br /> associated with current practices. <br /> Ae W.
