Design and Implementation of Population Census Data Collection System Based SIMG

摘要: 设计了人口普查多级网格(SIMGPC)的结构体系,重点探讨了网格划分、编码方法和网格数据库等关键技术,并实现了一个带有空间信息编码的人口普查数据PDA采集系统。

Abstract: The core idea of Spatial Information Multi-grid(SIMG) is introduced and the structure of spatial information multi-grid for population census(SIMGPC) is designed.The key technologies are expatiated on the method to measure off grid,code and SIMG database.A population census data PDA collection system with spatial information code is designed and implemented.
