  census gis
Finally, using the illustration of the census data of Guangzhou city, the paper analyzes and elaborates some issues on the urban census GIS designing, such as data management, data warehouse building, and data analysis.
      
And then a three-tier construction architecture for the urban census GIS is proposed.
      
This paper first briefly looks back on the history of census GIS around the world, and then summarizes some preponderances of developing urban census GIS in China.
      
In addition, the census GIS contains layers of streets and statistical areas for the whole country.

Census data is not only useful for the whole country,but also valuable to the local levels [FK(W25。40ZQ]and even to the private sectors.If we use some advanced information technologies in the 5th National Census,we will make the Census information more valuable and useful.Now,GIS technology is commended to deal with demographic problems in China.We are very familiar with GIS technology,but we did little in Census area.We should do some application research on Census GIS immediately. Firstly,this paper introduces the application background of Census GIS around the world.Now,there are many successful systems in developed countries,such as TIGER in USA,HMSO in England,etc.All these systems are very helpful for us to develop our own Census GIS.In recent years,information technology has been widely used in China,and many cities have prepared abundant digital information,such as digital maps,Orthophotos,data on industry,etc.There are good conditions to develop Census GIS in many cities,especially in metropolises in our country. Secondly,a three_layer structure for Census GIS designing is proposed,which are the data layer,the management layer,and the application layer.As a typical example,Guangzhou city is picked up in this paper.①The data layer in Guangzhou Census GIS includes some typical integrated urban data (about Census,industry,terrain,etc.).②Census database and data warehouse based on integrated data are comprised in the management layer.③Four application systems (for integrated application,for demographic task,for decision support,and for information distribution based on Internet) are included in the third layer. Finally,three issues on Census GIS implementing are discussed in brief.①Be sure to find an efficient way to manage the integrated data,be sure to choose a uniform geographic coordinate system and an effective geocoding method.②To build a data warehouse based on integrated urban data,then develop a decision support system (DSS) based on the data warehouse.③To use some useful analysis tools such as on_line analysis process (OLAP),data mining (DM),and spatial analysis,etc.

分析了国内外人口地理信息系统的发展概况 ,简要总结了目前我国建立城市人口地理信息系统的技术、数据基础和社会背景 ,初步提出一种建设城市人口地理信息系统的三层结构模式。以广州市的具体情况为例 ,探讨了人口地理信息系统建设过程中数据选择、数据库设计、人口数据仓库的建立、城市综合数据分析方法等关键问题。

In recent years,many researches are focused on the uncertainties of GIS data.It can be found that most of these researches are focused on the uncertainties of spatial data while a few are on the attribute data.In this paper,the authors try to integrate the uncertainties of spatial data and attribute data to analyze some problems on the data uncertainties in Census GIS.This paper suggests considering the uncertainties of spatial data and attribute data at the same time in GIS analysis and application.On...

In recent years,many researches are focused on the uncertainties of GIS data.It can be found that most of these researches are focused on the uncertainties of spatial data while a few are on the attribute data.In this paper,the authors try to integrate the uncertainties of spatial data and attribute data to analyze some problems on the data uncertainties in Census GIS.This paper suggests considering the uncertainties of spatial data and attribute data at the same time in GIS analysis and application.On the basis of the characters of Census GIS,the authors concludes three kinds of data uncertainties in Census GIS.Then,some related contents,reasons,and the influence of these uncertainties are discussed in detail.On the basis of the data uncertainties discussed in this paper,the authors propose some methods to resolve the related problems.Accordingly,some concise formulae are used to illustrate the uncertainties and the related models.

针对系统数据源、数据模型的不确定性以及分析过程中引入的不确定性等问题进行了系统的研究 ,并归纳了各种不确定性的影响模型 ,进而提出了一套人口GIS数据优化建模以及分析过程中人口密度中心建模的思想和实用方法 ,用于克服人口GIS中数据的不确定性的影响。

A census GIS,which named as Pudong New Area Census GIS(PucGIS),was(developed) using techniques of component GIS,data ware house,demographic and population modelling.The detailed demographic index was designed in the system for exploring more information from census database.The technology of data ware house was used in census database designing,Pudong New Area census data was partitioning in spatially by the census block,which coincide with the political boundary of Jiedao or Zheng.This two level database improving the execution efficiency of PucGIS greatly.

以第五次人口普查数据为基础,综合利用GIS构件技术、数据仓库技术和模型集成技术建立了浦东新区人口普查GIS(简称PucGIS).在PucGIS的实现过程中,以充分提供人口统计信息为重要目标,详细设计了人口指标体系;运用数据仓库技术设计了两级人口数据仓库管理体系,极大地提高了系统的效率.
