Dynamic Visualization of Natural Area in Web Platform Case: Block 130 Pibeshk
Abstract
Management, utilization and protection of natural resources require accurate and timely data. 3D visualization of vegetation cover where implemented in web bed, in way to be displayed and have a dynamic movement in virtual environment, facilitates the access of relevant experts to the simulated forest environment. The study area is a vegetative part of tropical area of Oman Sea in deprived province of Sistan and Baluchistan. Due to the high dispersion of vegetation and the required precision, using aerial photos is considered as a useful tool for preparing the database in GIS environment. In the present study, the spatial and descriptive database including the information of degree of density, type of vegetation cover and area and three - dimensional models of forest species were used to visualize in Google Earth environment. The final results indicate that three-dimensional visualization of the data extracted from aerial photos had a high precision and can be implemented in Google Earth environment and the conformity of forest boundaries in aerial photos with their boundaries in Google Earth has a significant accuracy. In addition, sharing of natural resources data in the context of web will enhance and makes efficient the process of management and decision-making of the experts.
