摘要：The Turkey's general cadastre works have not been completed as yet. Even some of the areas where cadastre has been finalised, forest properties are still under social pressure and as such these areas are in conflict with residential uses calling upon courts to resolve the problem. In order to determine precisely the right historical land cover status of the areas under dispute, it is possible to benchmark the new and old aerial images of the same area except in case where legal documents are present. Any changes occurred in forest cover types over half a century could only be detected and monitored with this approach. 1/25000 scale standard topographic maps, historically taken aerial images and forest management plans are used as evidence documents for lots under dispute and in the court. The classic evaluation methods such as visual inspection are seen inadequate and inaccurate in resolving forest property problems. Creating digital maps from aerial images using the digital photogrammetric method has proven possibilities with desired accuracy. Such approach is more reliable and faster than the classical methods. Using the digital photogrammetric method, more accurate data can be gathered and used to solve the problems in forest properties. Then courts will make right, fast and reliable decisions about the problems. In this study, a district whose property cadastre works was completed in 1985 and with many lots in dispute is selected as a pilot area for a case study. Panchromatic aerial images covering the case study area were taken in 1955 and 1982 in the scales of 1/35000 and 1/23000 respectively, and scanned with 21 micron geometric precisions. Adequate number of control points for digital photogrammetric evaluation are established in the pilot region. These control points are surveyed with the nation-wide coordinate system using GPS technology. As a result of digital photogrammetric evaluation, the forest property's boundaries are determined with ±1-1.5m accuracy using these aerial images. With this approach, creating digital maps based on forest cadastre maps and forest management plans will be formed. The approach provides important contribution to the forest cadastre works that have been major bottleneck in Turkey. Furthermore the forest property problems will be solved easily and the objections will decrease in forest property boundaries
