【摘要】：为进一步推广国产卫星遥感影像数据在国土资源行业中的应用,针对土地利用监测与现状变更调查业务需要,探索"高分二号"(GF-2)卫星数据在土地利用动态监测与现状变更调查工作中的适用性及其潜力。以四川隆昌县金鹅镇为研究区,通过定性、定量评价原始影像数据质量,对比分析同级数据,结合多方法提取变更信息,从不同角度测试其变化监测能力。结果显示,GF-2卫星数据地物清晰,光谱信息丰富,目标解译性较好,影像效果优于"高分一号"(GF-1)和SPOT6数据;主成分分析法和光谱变异法的结合可快速发现影像上的变化信息,GF-2卫星影像能满足土地利用变更监测的需求,具有较大潜力及价值。
[Abstract]:In order to further promote the application of domestic satellite remote sensing image data in the land and resources industry, aiming at the needs of land use monitoring and status change investigation, To explore the applicability and potential of GF-2) satellite data in land use dynamic monitoring and status change investigation. Taking Jinwan Town, Longchang County, Sichuan Province as the research area, the quality of original image data was evaluated qualitatively and quantitatively. By comparing and analyzing the same level data, combining with multiple methods to extract the change information, the ability of monitoring the change is tested from different angles. The results show that the ground features of the satellite data are clear, the spectral information is abundant, and the interpretation of the target is good. The image effect is superior to that of GF-1 and SPOT6 data, and the combination of principal component analysis and spectral variation method can quickly find the change information on the image. The GF-2 satellite image can meet the needs of land use change monitoring and has great potential and value.
