B/S架构下地理信息数据加工管理系统地图相关算法的探讨

在地理信息数据加工管理系统中,需要将图幅分割为大小合适的块,然后分配给作业人员绘制或编辑,最后再统一接边和汇总。实践表明,图形化的操作方式更易于用户接受,B/S架构解决了国外项目的甲方审查项目进度问题,因此B/S架构下具有图形化管理功能的地理信息数据加工管理系统应运而生。地图的基本操作是比较复杂的,本文提出的四个基本算法是一套完整的解决方案,主要解决了在B/S架构下前后台通过数据异步通信的同时,采用不同的算法,达到前后台数据通信的同步性,从而保证了地图展示和操作的一致性。

Discussion on Map Algorithm in Geomatics Information Data Processing Management System with B/S Architecture

We will divide mapsheet into blocks of suitable size in geomatics information data processing management system.Then we will assign them to workers to draw or edit.At the End,mapsheet blocks will be edged or collected.Practice shows that graphical operation is easier to be accepted by workers or managers and the B/S architecture solves the problem when the foreign party reviews the project scheduling.So B/S architecture geomatics information data processing management system came into being.Basic map operation is more complex.This article proposes 4 basic algorithms which are a set of solutions to solve the problem of asynchronous communication between B/S architecture front and back and to achieve the synchronization by adopting different algorithms,thus ensuring the consistency of display and operation of the map.
