In February 2006 the Director General of the State Forests appointed a task team for a test project to examine the use of satellite imagery. The commissioned task was to test the possibility of updating forest digital maps with the use of satellite images as well as to test the use of those images for other purposes. In the project, high resolution satellite images were used made by IKONOS satellite and the ortophotomap produced of those images. The test positively verified the possibility to use the ortophotomap for updating forest digital maps. In the next step it was decided to test, whether the ortophotomap could be the source data to verify the accuracy of the existing vector maps and to make new ones. To do that forest compartments of two forest districts picked by chance were digitalized and then the geometric shapes of objects created in this way were compared with the same objects on the existing maps. In conclusion of the test it was ascertained that the use of the ortophoto map made of high resolution satellite imagery from IKONOS satellite could improve accuracy but the imagery itself is not sufficient data source to produce all elements of the forest digital map.
