GPRS/GIS技术在自动雨量监测网中的应用

为提高沈阳市气象事业的现代化水平和服务水平,利用分组无线业务(GPRS)和地理信息系统(GIS)技术将分布在沈阳市各个县区的46个自动雨量站组建成自动雨量监测网。GPRS具有快捷登录、高速传输、永远在线、按量计费等优点,为监测网提供了可靠的通信子网。GIS在信息处理上具有空间分析的优势,不但可以进行自动雨量站的空间定位、雨量属性查询,还可以利用空间插值方法将离散的雨量数据转换成连续的雨量空间分布,使雨情的表达方式更为直观,提高了雨情的分析与处理水平。

Application of GPRS/GIS Technology to Automatic Rainfall Monitoring Network in Shenyang

The Shenyang Automatic Rainfall Monitoring Network(ARMN) is set up by using General Packet Radio Service(GPRS) and Geographical Information System(GIS) technology.It is composed of 46 automatic rainfall stations(ARS) distributed in the Shenyang area.GPRS has advantages of "fast access time," "high speed data transmission," "always online" and "pay by transfered data." It provides a reliable communication sub-network for ARMN.GIS has the advantage of spatial analysis in processing information.It can not only get the locations and query the rainfall attribute of ARS's,but also convert discrete rainfall data into continuous spatial distribution,which allows more direct representation of rainfall conditions.GIS improves the analysis and processing level of rainfall data.
