| 5. An inexpensive process for 350–1100 nm wavelength aerial photography for agro-environmental studies - Rafał Pudełko Abstract. The aim of this work was to present the possibilities of obtaining four-channels of aerial photographs (blue, green, red, infrared) and their use in agriculture research. Two synchronised and gyro-stabilised digital cameras FujiFilm IS-1 sets installed on a Cessna airplane were used. The digital cameras used in the study were factory set and adapted to perform photos in the 350–1100 nm wavelength. To separate the photographs content into spectral channels, selective fi lters were used and installed on the lens as well as photographs from two cameras were combined in a GIS computer program. High-resolution multispectral photographs were the source material for the spatial analyses. For example, the analysis can be used in fi eld monitoring – e.g. vegetation index (NDVI, VARI) map drawing. In this work, an evaluation of the cost involved in obtaining this type of data was presented. key words: remote sensing, image processing, computer vision, NDVI, VARI |
