In the retrospect of four months later, we can count the Conference as a great success. The theme – Research for Rural Development - attracted participation more than 200 researchers with very different backgrounds. There were 114 presentations from different universities of Lithuania, Estonia, Ukraine, South Africa and Latvia. Thank you for your participation! I’m sure that you have learned from the presentations and discussions during the conference and you can use the outcomes in the future. The cross disciplinary proceedings of the Annual 18th International Scientific Conference “Research for Rural Development 2012” is intended for academics, students and professionals researching in the area of crop production, animal breeding, agricultural engineering, agrarian and regional economics, food sciences, veterinary medicine, forestry, wood processing, water management, environmental engineering, landscape architecture, information and communication technologies. The proceedings will be useful for researchers in educational sciences, too. The papers are grouped according to the sessions in which they have been presented. Finally, I wish to thank Organizing and Scientific Committee and the sponsors for their great support to the conference and proceedings.

The objective of research was to explore remote sensing methods to determine individual tree position using LiDAR and digital aerial photography in Latvian forest conditions. The study site was a forest in the middle of Latvia – in Jelgava district (56º39’ N, 23º47’ E). Aerial photography camera (ADS 40) and laser scanner (ALS 50 II) were used to capture the data. LiDAR resolution was 9p m2 (500 m altitude).
