| 摘 要： | 现有的移动GIS产品大部分是基于WindowsCE平台用EVC开发的,移植性较差。在多操作系统共存的现实情况下,仅仅开发单一平台的产品无法满足应用的需要,可跨平台GIS提供了这一问题的解决方案。Super-Waba是一个可跨平台的类Java虚拟机,本文提出了基于SuperWaba实现跨平台GIS的流程,并据此开发了嵌入式环境下地图显示系统,具有良好的可移植性。该系统利用PDB(Pilot Database)管理分块地图数据,应用分块数据增量加载策略,很大程度上提高了地图显示速度。实验表明,基于SuperWaba的移动GIS能够灵活地跨平台移植,具有很好的应用前景。 |

| Abstract: | The existing mobile GIS software,which commonly developed with EVC based on Windows CE platform, have less portability. It is hard to meet the demand in the situation of multi-OS coexist. The portable mobile GIS can resolve the problem. This paper introduced a java-like portable virtual machine SuperWaba, and a program to realize portable GIS based on SuperWaba. An application of map display in the embedded environment is designed according to the program. The PDB (Pilot Database) which applied to manage map data and the strategy of dynamic data loading boost the map display. The experiment shows that it is feasible to develo Pportable mobile GIS based on SuperWaba. |
