基于BDS与GPS的土地利用变化测绘

Land use change surveying and mapping based on BDS and GPS

在人力和地质不断变化的背景下,必须及时进行土地利用变化测绘来保证土地资源的可持续发展,常规的土地利用变化测绘方法测绘精度低,无法满足快速变化的土地测绘需求。因此,基于中国北斗卫星导航系统(BDS)与全球定位系统(GPS)设计了新的土地利用变换测绘方法。首先,处理了土地利用变化测绘数据,基于BDS与GPS处理了土地变化测绘遥感影像;其次,检测了土地利用变化测绘遥感影像变化特征;最后选择了土地利用变化指数,实现了土地利用变化测绘。实验结果表明,设计的土地利用变化测绘方法的测绘精度高,符合现有的土地利用变化需求,有一定的应用价值。

Under the background of continuous changes in manpower and geology,land use change surveying and mapping must be carried out in time to ensure the sustainable development of land resources.Conventional land use change surveying and mapping methods have low surveying accuracy and cannot meet the rapidly changing land surveying and mapping needs.Therefore,a new land use conversion surveying and mapping method was designed based on BeiDou navigation satellite system(BDS)and global positioning system(GPS).First,the land use change surveying and mapping data were processed,and the remote sensing images of land change surveying and mapping were processed based on BDS and GPS;secondly,the land use change surveying and mapping remote sensing image change characteristics were detected;finally,the land use change index was selected to realize the land use change surveying and mapping.The experimental results show that the designed land use change surveying and mapping method has high surveying accuracy,conforms to the existing land use change demand,and has certain application value.
