A technology for reindeer pastures inventory on-line construction from optical remote sensing data was developed and verified for reindeer husbandry areas in northeastern European Russia. The obtained results are represented by a GIS-system incorporating attributive tables of land-using orientation. The inventory results take into account the seasonal and interannual variability of pastures conditions. The primary results of processing are geobotanical maps and quantitative characteristics of individual stock fodder units (lichen and green (shrub, herb) phytomass). Quantitative characteristics of vegetation cover were calculated using the principles of spectral decomposition of mixtures (Spectral Mixed Analysis). The materials obtained constitute a spatially organized database including polygonal objects (vector layers of reindeer husbandry units) and attribute data related via personal identifiers. The results are used to make economic estimates (reindeer capacity, number of pasture days, etc.) based on previously established and regionally adapted coefficients. The advantages of the suggested technology (low subjectivity, costs, accuracy) over traditional systems are discussed.
Keywords: reindeer pastures, spectrazonal satellite data, inventory of vegetation resources
