- 536 - of vegetation and other objects of nature, the number of orienting points reflected on the multispectral aerial photographs increases compared, with panchromatic aerial photographs by 2 times in forests that have been, in utilization, but by 3-4 times in a virgin forest. Among the total number of forest compartments detected on panchromatic aerial photographs, 50-75 per cent require precise placement of boundaries by visual examination, while with false color multispectral photographs only 10-20 percent need the verification of such kind. The degree of ease of detection of boundaries of forest compartments on false color multispectral aerial photographs is less dependent upon the scale compared to panchromatic photographs and thus permits the use of aerial photographs with smaller scales for accurate surveying work [6]. As well as the division of the forest stock into forest compartments, aerial photographs are used in forest inventory for direct forest estimation. It was based on the rational combination of interpretation of false color multispectral aerial photographs with the scale 1:15000 with ground forest estimation [ 4 ]. The interpretation based on the new technology is carried out by the method of analyses and measurements that provide the intensive investigation of the object, the development of measuring interpretation, and correlation between interpretation indices and estimation ones. The study and maintenance of mutual bounds between the interpretation indices, reflected on the aerial photos and estimation indices is carried out in the homogeneous woody vegetation type areas. For the purpose special test sites are used and data of selected measuring-innumerative estimation in the most typical forest compartments are made. Measuring data in the test sites and typical forest compartments provide the following relations: between diameters of crowns and diameters at breast height; between heights and diameters at breat height; between heights of trees and heights to the maximum breadth of their crowns; between heights and diameters of crowns, heights of trees and heights to the ends of crowns, between crown-density and crown stock; between the number of visible and invisible trees on aerial photos: and there also exist many inter relationships between diameters of crowns, age and the stock, height and overhead cover density. The stereoscopic analysis of aerial photos for the measurement of difference in absolute parallax and for some other measurements, various stereoscopes and other stereo instruments are used as well as a measuring lens and other devices. With the aid of the method of analysis and measuring (or just measuring) the composition, the density (crown density) is determined at the laboratory on the base of aerial photos. Due to the difference in absolute parallax, the height is determined; on the basis of correlations in the composition, density, height and diameter of crowns, the diameters of trees and the growing stock are calculated. The ecological conditions are determined on the basis of indirect indices: in accordance with certain forms of relief, tone and color of imagery, the structure of overhead cover and so on. Non-vegetated areas (deforestation, moors, fields) are interpreted on
