บทคัดย่อ (EN): Light detection and ranging (LIDAR) technology was used as tool to measure the girth of 3,320 Hevea brasiliensis trees in the Malaysia Rubber Board (MRB) Experimental Station, Kota Tinggi Johor as a pilot project in January 2012. LIDAR is an optical remote sensing technology that can measure the distance to, or other properties of a target by illuminating the target with light or laser. This technology uses a 3D laser scan to measure the tree’s diameter at breast height (DBH). LIDAR was used along with conventional measuring tool to measure the DBH of rubber trees. The data from both measuring tools showed that the measuring accuracy were comparable with means of girth for LIDAR (0.3835m) and mean of girth for caliper (0.3434m), p-value =0.004 Even though the results show that measuring accuracy of both methods was comparable, the LIDAR technology was less labour intensive as it was able to measure DBH at a wider area in a short amount of time. Meanwhile the DBH of every single tree had to be measured when using the conventional measuring tool. LIDAR was also found to be cost effective in completing the field data collection as well as analysis of data. Unfortunately the accuracy of the LIDAR is dependent on the condition of the area to be measured.
