Submersed land area including different utilizing type by sea water are calculated and the potential economic loss and population affected by the submerged disaster are assessed for no defence ， different sea - level rise and high water level . furthermore , special topic maps of fatalness of sea level rise , vulnerability of land system , socio - economic and ecological vulnerability , and defending ability are produced . the following results are combined with the basic study cell based on area source model following mathematical models of risk evaluation , considered of defence or no defence 运用海平面上升灾害危险性、土地系统易损性、社会生态经济易损性和抗灾能力的数学模型，在mapinfo软件下运行，得到该区上述四种评估因子的专题图；并分别按照考虑抗灾能力以及不考虑抗灾能力两种情况，用海平面上升灾害风险评估模型融合各因子，得到辽河三角洲（盘锦市）海平面上升灾害综合风险评估图。
The function of draining management module is to calculate the pipe maximal flux and the average flux by recursion arithmetic and the mixed water quality count , to export kinds of special maps ( according to water target , flux and pipe diameter ) . the function of database management module is for database establishment , database maintenance , data input , data export . the function of query and statistics module is to manager the database of drainage pipe network , which was established by database management module 用户管理模块主要用来管理使用系统的用户属性；排水管理模块主要是利用递归算法计算管段内最大流量、平均流量，一般的水质混合计算和各种专题图的输出(按水质各指标、按流量、管径等) ；数据管理模块主要完成污水管网gis系统数据库的建立、日常维护以及数据的输入、输出等功能；查询统计模块主要是对利用数据管理模块建立好的污水管网数据库进行信息管理，其主要功能有管网检索、查询、统计等基本功能。
On the base of the grading model , the article discusses the important effects of farmland grading course , and the whole grading processing . thirdly , the author implements a farmland grading information system . the system selects the new grading model as farmland grading method , component geographic information system ( gis ) as developing means 系统实现了地图集管理、地图操作、地图编辑、属性数据管理、外部属性数据库的连接、定级因素的维护、定级因素权重维护、定级指标体系、因素数据表的创建、定级处理、专题图的制作和系统管理等功能。
For that reason , the " automation of cross - platform forestry mapping " adoptes the template technique and establishes the database of the forestry map template . the forestry sign database is established according to the principle of information share . make use of twice developments to make up the shortage of mapinfo in forestry map expressing 为此在“跨平台林业地图专题图自动化”中，采用了专题制图模板技术，建立了林业地图模板库，取得较好效果。基于信息共享的林业符号库：在系统开发中开发了基于truetype的林业符号库，方便用户在不同系统中使用。
Gis technology provides the method of visualization , along with the data mining technology , can convert the available data into visual ones related with map objects through the special technology of gis and present the data in the map in the form of thematic pictures . it also can visualize the market situation , determine where the potential resources are and predict the development of market , help to make plans and dispose routine transaction for banks Gis技术提供了可视化的方法，结合数据挖掘技术，可以将现有的大量业务数据通过地理信息应用系统的独特关联技术，把业务数据转化为关联地图对象的可视属性，并采用专题图的形式直接显示在地图上，从而形象化地显示地理分布状况、决策哪里可有潜在的银行、预测市场的未来以及支持银行的业务规划和运作。
It put out the system requirements from the whole structure , function structure , developing mode , user management , the design of software and database , safety design , system running efficiency , developing plan , etc . it put out the basic graphics operation , the module building and editing of the electrical network , the devices records and function management the devices operating management , the function producing the electrical subject chart , the outside interface function , the in - out function and webgis , etc . it discusses some advanced functions including the theory loss and practical loss computing of the distribution line , the reliability basic data producing and conversing tools , power cut management , the load supplying from other ways , the repairing management on user fault reports , th e new load installing assistant function , the management of hanging the cards and simulating operation , the monitonng and analyzing management of the running information , load monitoring and load density analyzing function and so on 从系统总体结构，功能结构，开发模式，用户管理，软件和数据库设计，安全性设计，系统运行效率，开发计划等方面满足了系统的总体要求；系统实现了基本图形操作，电网建模与编辑，设备台帐及运行管理，设备操作运行管理，电力专题图生成，外部接口，输入输出， web - gis等基本功能;系统还具有配电线路理论线损计算及实际线损计算，可靠性基础数据生成和数据转换工具，停电管理，负荷转供功能，用户报修管理，用户报装辅助，挂牌管理和模拟操作，运行信息分析监控管理，负荷监控及负荷密度分析等高级功能:并能从运行方式，用户权限，运行日志三个方面阐述本系统的管理方式。系统总体结构合理，功能及接口齐全，配置扩展方便，可操作性强。
The office also provides extensive cartographic services for many government departments . these include the production of colour geological maps , thematic maps , weather forecasting plans , pollution control maps , aeronautical charts , electoral boundary maps , and plans for land disposal and resumption 测绘处又为其他政府部门提供广泛的制图服务，例如绘制彩色地质图、专题图、天气预测图、污染控制图、航空路线图、选区分界图，以及用于批地和收地的各类图则。
Forestry department obtain basic data and form map in counties mostly through the second class investigation of forest resource , but the updating and utilizing of the data is still rest on the phase of conventional handcraft , especially on the drawing of the forest mapping ; moreover , the categorical data and the spacial data is detached each other 我国大部分县级林业部门在利用森林资源二类调查成果获取基础数据和形成图面资料后，对数据的更新和利用很大程度上仍然停留在传统的手工处理的阶段，尤其是在林业专题图的绘制方而。
The system ' s development uses gis technology fully . it realize functions that all sorts of pipes , valves and ditches " information input , manage , query , analyze and protract , output theme map . it satisfied all sorts of pipes " layout , prove , maintenance , construction and management demands 系统的开发充分利用现今蓬勃发展的gis技术，实现各类专业管线、阀门、沟道等的信息输入、管理、查询、分析及各类专题图的绘制、输出等功能，满足了地下各类管线的规划、勘探、维护、施工和管理的需要。
