资源简介：
The Urban Landsat: Cities from Space data set contains images for 66 urban areas and the raw, underlying data for 28 of these places. Each image shows a Landsat false color composite in UTM projection. The R/G/B layers correspond to TM/ETM+ bands 7/4/2. Each pixel is 30x30 meters in area and most images are 30x30 km in area. A 2% linear stretch has been applied to the images. The Landsat data files contain six reflected bands of calibrated exoatmospheric reflectance stored in ENVI band sequential (BSQ) format. Geographic coordinates are included in the header files. The data files contain 1000x1000x6 4 byte floating point numbers as indicated in the header files.
《城市Landsat：太空中的城市》数据集包含66个城市区域的图像以及其中28个地点的原始基础数据。每一张图像展示了在UTM投影下的Landsat假彩色合成图像。R/G/B层分别对应于TM/ETM+的7/4/2波段。每个像素的面积为30x30米，大多数图像的面积为30x30平方公里。对图像应用了2%的线性拉伸。Landsat数据文件包含六个经过校准的外大气反射率的反射波段，存储在ENVI波段顺序（BSQ）格式中。地理坐标包含在头文件中。数据文件包含1000x1000x6个4字节浮点数，如头文件所示。
