Application of satellite images for the estimation of forest inventory indices

Purpose.  Estimation of the state of forest stands using remote sensing data and statistical inventory data and the comparison of forest inventory indices with forest management materials. Methodology. Remote sensing data were used for the investigation of inventory indices. Inventory indices of forest stands of NNP “Skolivsky Beskydy” and ascertain edges of forest massif were done with Landsat ETM+ data (resolution 30 m) and Quick Bird data (resolution 0.6 m).

Terms qa decryption railway transport data using digital aerial photography

Objective. The aim of this study is a reasonable definition of the conditions which must be satisfied for digital aerial image for high-quality recognition objects of rail transport with the aim of creating a plan with scale of 1:500, and the experimental study of the quality of rail transport objects interpretation on digital aerial images. Method and results. For inventory of land and rail transport objects based on the use of digital aerial survey it is necessary to ensure receiving  of quantitative and qualitative characteristics of the objects that meet the requirements of the branch.
