Simulation technology of damage effects of airport

ZHANG Peng; FAN Qiao-Yun

A method of getting tile image groups of airport before damage from Microsoft Virtual Earth image database was proposed. The storage structure of these images in remote database was analyzed 半by using quadtree data structure. High-resolution image of airport before damage was developed by organizing these images together. After this, image projection method, especially the method of longitude and latitude registration was studied under WEB mercator projection. So geographical coordinate can be projected to local image pixel coordinate. The depth and visible diameter of craters caused by kinetic projectile on concrete runway were simulated with classical Bernards Formulas on Depth of Projectile Penetration in Rock. Finally the simulation software was designed with 2D image generated technology. With position and other property of the crater, the virtual damaged airport image was derived by superposing the simulated crater images on the image of airport before damage.
