Sažetak
The forest stand volume assessment is one of the most important tasks in the forest inventory and on of the most valuable information in forest management planning.Tradional approach in Croatia, even in forestry legislature prefers terrestial measurement using sampling methods and volume tables.In a lot of cases the foresters measure all trees within the forest stands. It is time and labour consuming and very expensive job. In Croatia, where about 15% of forest area is still mined it is also very dangerous job.Remote sensing methods for the stand volume assessment become acceptable in a lot of countries.Lot of investigation have been done to evaluate these methods for practical application.All these facts help that the interest for the remote sensing methods for the stand volume assessment among foresters working in forest inventory raises ina a last five years.Many of them have prepared their master thesis about possibilities of remote sensing in a stand volume assessment.The idea of all these investigations was to find out method that is simple and accurate enough to be applied for the stand volume assessment.Several approach have been investgated:visual interpretation of aerial and satellite images, the use of regression models based on satellite images and multivariate analysis.Results of all these investigations show that stand volume can be assessed with the diverse accuracy, from +/-1% to+/-15%.The cost benefit analysis shows that the remote sensing methods are about 35% chipper than terrestrial methods.In this paper the evoluation of the results are given.
