摘要
本文在研究信息化技术条件下嵌入式设备的成本、环境因素、数据特性和应用特性的基础上,探讨了嵌入式环境下地理空间数据在组织和处理等方面所面临的主要问题,针对地理空间数据在嵌入式环境下的表示模型、显示数据集合和与之对应的约束关系,设计了组织技术方法和策略。实验结果表明,组织技术方法和策略显著地改善了嵌入式环境下地理空间数据组织的效率,提高了其在嵌入式环境下的调度和显示速度。
Based on the comprehensive research of the cost, environmental factors, data and application features of the em- bedded equipment, the paper discusses the existing problems of geospatial data organization and processing in embedded environ- ment. According to the representation model, display data set and corresponding constraint relationships, the paper presents some methods and strategies for geospatial data organization and processing. The results show that these methods and strategies can dra- matically improve the efficiency of data organization and increase the controlling and display speed in the embedded environment.
