A digital orthoimage is a raster image processed from vertical aerial images in which displacement in the image due to sensor orientation and terrain relief have been removed. Orthoimagery combines the image characteristics of an image with the geometric qualities of a map. Unlike planimetric maps which depict natural and manmade features by means of lines, point symbols, texts and polygons, orthoimagery illustrates the actual images of features and are thus more easily interpreted than regular maps. The normal orientation of data in an orthoimage is by lines (rows) and samples (columns). Each line contains a series of pixels ordered from west to east with the order of the lines from north to south. Each image tile is stored in industry standard TIFF (tagged interchange file format) with an associated TIFF world file. Aerial imagery was acquired between April 12 and 15 2015 from flying heights of approximately 1400-1640 feet above ground level (AGL). Each orthoimage tile is 2500feet X 2500feet in dimension, edge-tied with the adjacent tiles (no gap and no overlap). This dataset is published in NAD_1983_HARN_StatePlane_Michigan_South_FIPS_2111_Feet_Intl_feet.</span>
使用本网站或其中包含的内容，即表示您同意<u><a href='https://www.oakgov.com/open-data-terms'>使用条款</a></u>。 本MrSID文件源自2015年栅格数据集，该数据集包含8位、4波段（红、绿、蓝、近红外(NIR)）彩色正射影像。数字正射影像是经处理的垂直航空摄影栅格图像，已消除因传感器姿态与地形起伏导致的图像位移。正射影像兼具航空影像的图像特征与地图的几何精度。与通过线条、点符号、文字与多边形表示自然与人工地物的平面地图不同，正射影像直接呈现地物的真实影像，因此比普通地图更易于判读。正射影像的数据常规组织方式为行（rows）与列（samples）：每一行包含一系列由西向东排列的像素，而行的排列顺序则为从北至南。每幅影像瓦片采用行业标准TIFF（标签图像文件格式，Tagged Interchange File Format）存储，并附带对应的TIFF世界文件。航空影像采集于2015年4月12日至15日，飞行高度约为地面以上1400至1640英尺（AGL）。每幅正射影像瓦片的尺寸为2500英尺×2500英尺，与相邻瓦片边缘紧密衔接，无间隙且无重叠。本数据集采用NAD_1983_HARN_StatePlane_Michigan_South_FIPS_2111_Feet_Intl_feet坐标系发布。
