摘要
地理空间环境仿真中,为了实现模拟训练和仿真分析,需对不同区域内的地理数据进行迁移处理,以获得理想的地形模拟效果并降低对真实环境的依赖,从而支撑地形分析和路线规划等活动,以及在异域环境下完成方案评估与动态推演。地理数据迁移过程涉及位置变换、方向变换和大小变换,地理数据类型包括各种矢量格式或栅格格式的影像数据和高程数据等,故地理空间环境迁移时需综合考虑数据的转换率、准确度和完整性等。为满足地理空间转换场景需求,提出了一种高效的地理空间数据迁移方法。
In geospatial environment simulation,in order to achieve the simulation training and the simulation analysis,it is necessary to transfer geographical data in different regions to obtain the ideal terrain simulation effect and reduce the dependence on real environment.Thus,it can support activities such as the terrain analysis and the route planning,and then complete the program evaluation and dynamic deduction in exotic environments.The process of geographical data migration involves the position transformation,the direction transformation and the size transformation.The geographical data types include various image data and elevation data in vector or raster format.Therefore,the conversion rate,the accuracy,the integrity of data should be considered comprehensively during the migration of geospatial environment.In order to meet the requirement of geospatial transformation scenarios,an efficient geospatial data migration method is proposed.
