Abstract
Wetlands include myriad environmental types as defined by water, hydric soils, and specialized vegetation. Wetland environments are present in all climatic and topographic settings around the world. Much scientific research is directed toward wetlands, and small-format aerial photography has distinct advantages for certain types of wetland investigations, notably high spatial and temporal resolutions, relatively low cost, good logistics, and minimal environmental impacts. SFAP may be taken in all possible orientations and directions relative to the ground target and sun position, which provides for unique lighting conditions. SFAP spans the scale range 1:100 to 1:1000 and, thus, bridges the gap between ground surveys and traditional remote sensing for wetland research. Typical applications of SFAP are described for raised bogs in Estonia and prairie marshes in the Great Plains of Kansas as well as biocontrol of saltcedar (Tamarix sp.) in Colorado, United States.
