Geographic Information Systems and Remote Sensing are important contributors to Sustainable<br/> Forestry Management Plans. Remote sensing techniques for image interpretation provides the<br/> means to extract valuable information that could be expensive and time-consuming to obtain<br/> through field observations (Franklin et al. 2001).<br/> Spatial Products derived from the interpretation of airborne and satellite borne images feed<br/> Geographic Information Systems to develop strategies and methodologies for resource<br/> management, harvest planning, fire management, map production, and model predictions.<br/> (Yusmah et al. 2015)<br/> This study has three important objectives: to test the feasibility of template matching for the<br/> identification of single pine tree crowns, to conduct a delineation of pine plantations using<br/> relational features and to evaluate how single tree crown size affects the accuracy of the<br/> proposed method.<br/> Templates of single trees were produced in the software eCognition Developer. The sampling<br/> process comprised the random selection of 3000 single pine trees in 7 different test sites (test sites were grouped in 3 categories according to the single tree sizes). A first rule set to detect<br/> single tree crowns was developed in eCognition Developer, using three different template groups (4, 8 and 16 templates). Through an analysis of variance, the number of single tree<br/> crowns detected was compared for the different template groups.<br/> Using a second rule set in eCognition, the template matching algorithm combined with<br/> relational, spectral and contextual information were applied to delineate pine plantation areas.<br/> An accuracy assessment was performed in the test sites for all thematic classes identified.<br/> Finally, an Analysis of Variance evaluated the influence of single tree crown size on the overall<br/> accuracy.<br/> Potential applications and improvements to the proposed methodology for single tree crown detection and plantation delineation are proposed at the end of the document.
