土地利用现状一直是政府和行业行政管理部门十分关注的问题。以往,我们主要是采用层层汇报以及土地变更登记等手段来进行土地利用现状的调查和统计,但是这样的统计结果可信度如何,我们难以估计。采用遥感和 GIS 技术,可以非常快速、客观地反映出土地利用的变化情况。今年4月,国土资源部要求上海市房屋土地管理局对有关非法占用土地的情况进行调查并提供了两幅卫星遥感影像,为此,我们结合现有 GIS 数据库,对遥感影像进行了处理,得到了精度较高、易读易懂的图形数据,为局执法处、规划处等有关部门现场调查和校验提供了直观、科学、可靠的依据。
The status quo of land use has always been a major concern for the government and industry administrations. In the past, we mainly conducted surveys and statistics on the current status of land use by means of reporting at different levels and registering land changes. However, it is difficult to estimate the credibility of such statistical results. The use of remote sensing and GIS technology can very quickly and objectively reflect the changes in land use. In April this year, the Ministry of Land and Resources requested the Shanghai Housing and Land Administration Bureau to investigate the situation of illegal occupation of land and provided two satellite remote sensing images. For this purpose, we combined the existing GIS database to process the remote sensing images and obtained The high precision, easy to read and understand graphical data provide an intuitive, scientific and reliable basis for on-the-spot investigation and verification of the relevant law enforcement agencies, planning offices and other departments.
