摘要
通过研究哈尔滨经济和社会条件,对高分一号卫星数据进行数据检查、筛选、预处理并对研究区域土地覆盖信息进行分类,提取哈尔滨市区域2013~2014年土地覆盖变化信息。利用此应用案例,结合地理国情监测的特点进一步分析高分一号卫星数据的适用性;同时将高分一号卫星数据与同级国外卫星数据比较,研究国产高分数据在地理国情监测中的可行性。实验研究表明,高分一号卫星数据能够满足人们快速掌握各种土地覆盖信息的需求和对土地覆盖变化的动态监测需求。
In the paper the GF- 1 data is checked,screened,preprocessed and the land cover information is extracted from the research region by classification technology based on the Harbin social and economic knowledge. And the 2013’s,2014’s land cover change information is extracted. The applicability of GF- 1 satellite data is further analyzed using the above cases and being combined with the characteristics of the geographical conditions monitoring. Experimental research shows that GF- 1 satellite data can meet the requirements of people to quickly master the various land cover information and achieve a demand for land cover change dynamic monitoring.
