摘要
针对一些海岛面积受潮汐、海流影响较大的情况,提出了利用环境减灾卫星HJ-1的CCD数据进行海岛面积监测,并以唐山曹妃甸龙岛监测作为实验,计算了其潮汐条件下的最大、最小面积,分析了过去5 a中该岛的面积变化。实验结果表明,环境减灾卫星数据对于海岛测绘尤其是跟踪监测的效果良好。
In view of the special situation that some islands are affected by the tides and currents, applied feasibility of using environmental mitigation satellite HJ-1 CCD data to monitor the islands area was proposed in this paper. And taking the Caofeidian Long Island in Tangshan for example, the maximum and minimum areas of Long Island under its tidal conditions were calculated, and the area changes in the past five years were analyzed. The results show that the environmental satellite data is fit for surveying and mapping island, especially changes tracking, and the advantages are obvious.
