【摘要】：随着社会经济的迅速发展,公众服务地理信息系统在人们的日常生活中越来越重要。而互联网技术的普及,使得地理信息系统服务于每个家庭变成了可能。WebGIS已经成为GIS的主要形式。许多贴近人民生活的网站,也都加入了电子地图功能,即公众地理信系统,如百度地图、搜狐地图等等。虽然这些地理信息服务可以基本满足人民的生活需要,但随着城市的飞速发展,人民频繁地使用电子地图,目前的公众地理信息系统,存在很难满足数据及时更新,以及展示符合用户个人需要的信息的需求。因此,本文研究一种以志愿者式地理信息系统为基础的,一种更适合人民生活需要的地理信息系统。志愿者式地理信息系统的大体思想是用户可以以一种志愿者的身份,自愿的为系统贡献内容,并为其他用户所分享。这一技术的兴起,是由于近年来信息化产业已经进入了人们生活的各个领域,人民对地理空间信息的需求越来越大。以志愿者式地理信息系统为基础的公众服务类地理信息系统探讨与研究,目的是实现一种在建立并完善地理数据库时,将以志愿者模式的数据搜集作为一种数据新来源,将一般用户通过志愿者方式采集来的数据集合到原有的数据系统中,作为更新数据,并以按照用户需要的形式展示出来。用户可利用数码相机、手机等移动终端设备,采集个人需要的地理信息数据,然后,将这些带有位置信息的数据通过Internet上传到服务器上。技术人员或是专家对基于志愿者模式采集到的数据进行初始化处理并审核,最后添加到原有数据中本文的主要研究内容包括,首先讨论总结明确志愿者式地理信息系统的准确概念、技术特点、发展现状与应用成果和尚存在的一些问题的基础下,解决处理志愿者式数据采集多源性,如何与公众地理信息数据库相结合的问题,并建立一个基于志愿者模式的基础的公众服务系统加以验证。
[Abstract]:With the rapid development of social economy, GIS is becoming more and more important in people's daily life. With the popularization of Internet technology, it is possible that GIS serves every family. WebGIS has become the main form of GIS. Many websites close to people's life also add electronic map functions, such as Baidu map, Sohu map and so on. Although these geographic information services can basically meet the living needs of the people, with the rapid development of the city, people frequently use electronic maps, the current public geographic information system, it is very difficult to meet the timely updating of data. And the need to display information that meets the individual needs of the user. Therefore, this paper studies a kind of geographic information system based on volunteer GIS, which is more suitable for people's living needs. The general idea of volunteer GIS is that users can volunteer to contribute content to the system and share it with other users. The rise of this technology is due to the information industry has entered into various fields of people's lives in recent years, the people's demand for geospatial information is growing. This paper discusses and studies the public service GIS based on volunteer GIS, the purpose of which is to realize a new data source, which is based on the volunteer model when establishing and perfecting the geographic database. The data collected by ordinary users through volunteers is collected into the original data system as updating data and displayed in the form of users' needs. Users can use digital camera, mobile phone and other mobile terminal devices to collect personal geographic information data, and then upload the data with location information to the server via Internet. Technicians or experts initialize and review the data collected in the volunteer model and add it to the original data The main research contents of this paper are as follows: firstly, on the basis of summarizing and clarifying the exact concept, technical characteristics, development status and application results of volunteer GIS, and some existing problems. To solve the problem of how to deal with the multi-source of volunteer data collection, how to combine with the public geographic information database, and to establish a public service system based on volunteer model to verify it.
