In authors opinion,conversion from cartographic data to GIS database is essentially data model conversion according to modeling analysis.

本文以模型分析理论为出发点，认为制图数据向GIS数据的转换实质是数据模型的变换。

The geographical distribution of the genus Gastrolina(Chrysomelidae : Chrysomelinae) in China was analysed using GIS software.

本文运用GIS技术研究扁叶甲属Gastrolina在中国的地理分布格局。

Supervised and unsupervised image classification were applied to the study area TM image and t o the paddy field TM image. And the early rice areas were calculated by each met hod. Using the proposed methodology improved the quantitative accuracy of ear ly rice area estimated up to 93.98%, whereas it was 82.83%when image classific ation was used only. The extracted information from the c lassification is belonging to the early rice and not to any other vegetation. Si nce the GIS database is available, the method is easily applicable to any new RS images.

不同方法比较结果表明：非监督分类法不能用于提取丘陵山区的水稻种植面积；只用TM资料估算龙游县早稻面积，与统计数据相比，平行六面体分类法、最大似然分类法精度分别达到82.83%和59.95%；而用GIS 与TM资料集成技术对水田分布图进行分类估算早稻面积，平行六面体分类法、最大似然分类法的估算精度分别达到93.98%和60.65%，所以利用平行六面体分类法对南方丘陵山地早稻种植面积估算是可行的。

Firstly, this article detailedly introduces the GPS and GIS, explains their applications in the vehicle monitoring system, and gives the coordinate transform model which used compatibly in this system.

本文首先详细介绍了GPS、GIS系统以及它们在车辆监控系统中的应用，并给出了适合车辆监控系统使用的坐标转换模型。

The system is suggested to approach the problem by means of geographical information system component software. Because the GIS was integerated in the whole system , some of the traffic facilities will be displayed in the concreate map and become more easy to control and manage , in this way the traffic will also become more free,secure and efficient.

This paper contrapose the overhaul and maintenance of the power wire and transformer, make use of the AM/FM/GIS technology, exhibit the information required by equipment overhaul through images and texts. Supplied whole and intuitionistic information for the the overhaul and maintenance of equipment of power systems .

论文课题针对地区供电局所辖的变电站、线路设备的检修维护，利用AM/FM/GIS技术，将设备检修所需的各种信息以图形和文字的形成展现出来，为电力系统设备维护检修提供了完整的直观的信息支持。

The procedure of the analysis is as follows :first,the digital road map was made based on the paper map ofFangshan,southwest Beijing,andthefire distribution map was made byinputingthefire points collected withGPSinto the GIS.The road connectivity was obtained using the Axwoman to drawlines along the roads.Buffers onthe lines within a distance of 1 000m were made,and the curver fitting was analyzed between the fire numbers and the road connectivity.

首先对房山区的纸质地形图进行扫描，制作房山的道路分布专题图，并将GPS采集的林火火点位置转入ArcView GIS，制作林火火点位置图；用Axwoman扩展模块勾绘了道路，进行了道路连通度的分析，并以勾绘的连通线作了1 000 m的缓冲分析；以连通度与相应的缓冲区内的林火火点数作了拟合分析。

At last, this paper discusses the designation and implementation of a GIS/GPS/GPRS vehicle supervising system. This system produces a practical measure to resolve the problems in traffic control and management, such as vehicle hijacking, vehicle safe, vehicle management discommodiously.

在对以上理论研究的基础上，针对当前交通部门普遍存在的车辆管理不方便，车辆容易被盜等实际问题，提出了一个基于GIS/GPS/GPRS的车辆监控系统的设计方案。
