摘要
为及时发现各类违法违规行为,做到早发现、早制止、严查处,湖南省自然资源厅在季度卫片执法的基础上提出了月度卫片执法的工作思路。针对月度卫片执法工作“面积大、范围广、时间紧、图斑多”的特点,利用0.5~2 m分辨率影像,采用“机器+目视”解译双管齐下的方式,发现并提取可疑图斑;制作自动化工具赋予图斑土地管理信息属性、生成监测图斑信息;采用全球定位系统(GPS)技术,搭配外业调查系统,辅助外业执法工作;有效地实现了月度卫片“月发现、月预警、月处置”的工作目的。
To timely discover various violation of laws and regulations,to reach the goal of discovering fast,stopping fast and disposing strictly,on the basis of quarterly satellite image law enforcement,the department of natural resources of Hunan Province proposed the idea of monthly satellite image law enforcement.Due to the“large area,wide scope,short time and many spots”feature of monthly satellite image law enforcement,images with 0.5~2 m resolution were applied to discover and pick up suspicious spots through machine and eyes checking together;automation tools were created to give spots its land management information attribute and make the information visible;with the use of global positioning system(GPS)technology,cooperate with field investigation system and assist field law enforcement;effectively reached the goal of“discovering monthly,early-warning monthly and disposing monthly”.
