Landsat and MODIS data for the Coleambally Irrigation Area

The Coleambally Irrigation Area study site is a rice based irrigation system located in southern New South Wales (NSW, Australia; 34.0034E, 145.0675S) which has been extensively used for time series remote sensing research. Over the Coleambally 17 cloud-free Landsat-MODIS pairs were available for the 2001–2002 austral (i.e., southern hemisphere) summer growing season. Each image is 43 km in the north-south (N-S) direction and 51 km in the east-west (E-W) direction; an overall area of 2,193 km2 comprised of 1720 columns by 2040 lines at 25 m resolution. All Landsat imagery are ETM+ acquired by Landsat-7. Coleambally is entirely in the E-W overlap of two adjacent paths in the Landsat World Reference-2 system (i.e., Paths/Rows 92/84 and 93/84) allowing for an ~8-day repeat cycle. A separate folder contains a binary image for masking a selection of irrigated paddocks used for evaluation of accuracy of blending algorithms in land cover specific areas as described in the following citation:

科尔宾利灌溉区（Coleambally Irrigation Area）研究样地是一个以水稻种植为主的灌溉系统，位于澳大利亚新南威尔士州南部（NSW，澳大利亚；坐标为34.0034°E，145.0675°S），该样地已被广泛应用于时间序列遥感研究。
在科尔宾利灌溉区范围内，2001-2002年南半球夏季作物生长期内，共有17幅无云的陆地卫星-中分辨率成像光谱仪（Landsat-MODIS）影像对可用。单幅影像的南北向（N-S）长度为43 km，东西向（E-W）长度为51 km；整体覆盖面积达2193 km²，影像分辨率为25 m，由1720列×2040行的像素阵列组成。
所有陆地卫星（Landsat）影像均为陆地卫星7号（Landsat-7）搭载的增强型专题制图仪Plus（ETM+）所获取。
科尔宾利灌溉区完全处于陆地卫星世界参考系统2号（Landsat World Reference-2）中两条相邻轨道带的东西向重叠区（即轨道带/行号92/84与93/84），因此可实现约8天的重复观测周期。
另有一个独立文件夹，内含用于掩膜选定灌溉田块的二值影像，该影像用于评估针对特定土地覆盖区域的融合算法精度，相关细节如下文引用文献所述：
