ANALYSIS OF MULTITEMPORAL AERIAL IMAGES FOR FENYŐFŐ FOREST CHANGE DETECTION
This study evaluated the use of 40 cm spatial resolution aerial images for individual tree crown delineation, forest type classification, health estimation and clear-cut area detection in Fenyőfő forest reserves in 2012 and 2015 years.

| description | This study evaluated the use of 40 cm spatial resolution aerial images for individual tree crown delineation, forest type classification, health estimation and clear-cut area detection in Fenyőfő forest reserves
in 2012 and 2015 years. Region growing algorithm was used for segmentation of individual tree crowns.
Forest type (coniferous/deciduous trees) were distinguished based on the orthomosaic images and segments. Research also investigated the height of individual trees, clear-cut areas and cut crowns between
2012 and 2015 years using Canopy Height Models. Results of the research were examined based on the
field measurement data. According to our results, we achieved 75.2% accuracy in individual tree crown
delineation. Heights of tree crowns have been calculated with 88.5% accuracy. This study had promising
result in clear cut area and individual cut crown detection. Overall accuracy of classification was 77.2%,
analysis showed that coniferous tree type classification was very accurate, but deciduous tree classification had a lot of omission errors. Based on the results and analysis, general information about forest
health conditions has been presented. Finally, strengths and limitations of the research were discussed
and recommendations were given for further research. |
