随着网络技术的飞速发展,遥感影像技术的不断推广应用,网络地图显的尤为重要,涌现出了大量的电子地图相关的产品。国内在遥感影像方面起步比较慢,绝大多数是小规模影像数据处理系统,提供影像显示和浏览、几何校正和格式变换等简单功能,以处理单块影像为多,在处理大区域时,需将所有相关影像分块拼接起来,在提高空间连性的同时,降低了数据应用的灵活度,降低了多精度和多维度数据分析的有效性。
在遥感影像数据越来越丰富、精度越来越高的趋势下,开发遥感影像电子地图浏览系统就显的尤为重要。出门在外,随时随地都能掌握身处何地时,生活就会更有意义。
本文介绍了电子地图浏览系统在Wince平台上的应用。在Windows Mobile 5.0 Pocket PC SDK (ARMV 4I )平台上对整个浏览系统进行移植操作,实现电子地图在PDA上的缩放,平移,全图和查询等功能。

Abstract
As the technology of network developing fast and the technology of remote sense portrait ceaselessly application and dissemination, the map of network will change importantly. Springing up a large amount of products of electron map. In the homeland ,starting is comparatively slow in the field of remote sense portrait, the most is a small-scale portrait data handling system, the system provides simple functions such as portrait display and browsing, geometry adjustment and form alternation, more for the portrait handling a monolithic. When handling big area, we need putting all relevance portrait piecemeal split joint getting up together side by side. When improve company sex in space, we have reduced nimble degree of the data applies, have reduced the validity in many accuracy and many dimensions spends data analysis.
When the data is more and more rich and accuracy is more and more high in remote sense portrait, developing the electron map to browse system will be obvious very important. When we are outside and can grasp the body place always and everywhere time anywhere, life will be having more amusing.
This thesis talked about browsing system of the electron map that applies on the platform of Wince. Face to face entire browse system carrying out transplanting operation on the platform of Windows Mobile 5.0 Pocket PC SDK (ARMV 4I ). Realizing the function of electron map such as decreasing and enlarging, translating , satisfy picture and inquiry on the platform of PDA.
Keywords: Technology of remote sense portrait, browsing system of the electron map, transplanting.
