Tiivistelmä

Kite aerial photography (KAP) involves the use of large kites to lift camera rigs 50–150 m above the ground. Various types of radio-controlled, single- and dual-camera systems may be employed to acquire images in visible and near-infrared portions of the spectrum. KAP has many advantages for peatland research, including: high portability, rapid setup and operation, small crew, range of suitable weather and site conditions, high-resolution images, and low cost of equipment and operation. On this basis, KAP could be utilized for multitemporal imagery throughout the growing season and from year to year to document study sites. Kite aerial photography at Endla Nature Reserve in Estonia demonstrates the potential of this method for acquiring useful images in vertical and oblique orientations. Sun glint in oblique views (toward the sun) can highlight the presence of water bodies regardless of water depth or turbidity. Color-infrared KAP would be especially useful for separating different types of vegetation cover and water bodies in peat bogs. Kite aerial photography could represent one level of observation in a multistage and multitemporal approach that involves ground study, conventional aerial photographs, and satellite imagery.
