%X Rapid technological advances in the second part of the 20th century have brought about immense changes in data collection methods, especially in developed countries. In addition to standard terrestric data collection methods, forest data are increasingly being collected with remote sensing methods. The application of remote sensing reduces the amount of field work and offers the possibility of saving time and money.Satellite remote sensing is a very efficient method, while satellite images are a useful means for the surveillance and study of forest vegetation. Remote sensing is based on the prediction of the relationship between spectral reflectance and the observed variable. To interpret this kind of relationship, it is important to know the reflective characteristics of the target object (spectral features of vegetation, leaf, etc.), the size of area presentation (spatial resolution), and other factors such as topography, sun height, slope and orientation between the surveyed area and the survey sensor. A detailed and high quality analysis of satellite imagery, recognition and selection of certain data is highly dependent on image resolution, and especially on spatial resolution.Acquiring information on forests from satellite photographs of high spatial resolution has been the subject of a large number of research activities. One of the approaches involves classification based on pixel value, or regression analyses in which spectral records are used to predict classes or continuous variables of stand structure.The basic objective of this work is to explore the relationship between spectral reflectance recorded in the IKONOS satellite image of high spatial resolution and any individual stand parameter, as well as regression models for the evaluation of stand parameters.The main material for this work was provided by the IKONOS satellite image of high spatial resolution for the Spa va basin area. The survey was conducted on 18 October 2006. An IKONOS satellite image of the Spa va basin with an area of 132 km2 was delivered in 5 spectral channels: PAN (1x1m), and 4 MS Bundle. In the area of Vinkovci Forest Administration, within the management units encompassed by satellite surveying (MU Vrbanjske  ume, Kragujna, Slavir and Oto ke  ume), field measurements were conducted in management classes of pedunculate oak and narrow-leaved ash through all age classes (2nd to 7th age class), for the purpose of subsequent comparison of interpretations and assessments of structural elements. Based on field measurements and Management Plan data, a database with compartm
