Aerial Photo Viewer

<p style='text-align:justify;'>Oakland County has utilized Aerial Photographs for mapping purposes for decades. By comparing photographs taken at different times, county cartographers can create accurate and detailed maps of ever-changing features on the Earth’s surface. The process of comparing different aerial photographs and determining accurate measurements is called&nbsp;<a target='_blank' href='https://en.wikipedia.org/wiki/Photogrammetry' rel='nofollow ugc noopener noreferrer'>photogrammetry</a>. Maps created by using aerial photographs are called&nbsp;<a target='_blank' href='https://en.wikipedia.org/wiki/Orthophoto' rel='nofollow ugc noopener noreferrer'>orthophoto</a>&nbsp;maps.

<p style='text-align:justify;'>奥克兰县（Oakland County）数十年来一直将航空摄影用于制图工作。通过对比不同时段拍摄的影像，该县制图师可精准绘制地球表面不断变化的地物细节地图。对比不同航空摄影影像并获取精确测量值的流程，被称为摄影测量学（photogrammetry）。基于航空摄影影像制作的地图，被称为正射影像（orthophoto）地图。您可以回溯至1940年，探索70年前的本县风貌，亦可“立足当下”，查看分辨率高达3英寸的2025年超高细节影像！</p><p style='text-align:justify;'><img src='https://cdn.oakgov.com/webassets/StaticResources/it/gis/PublishingImages/MOTM_Assets/imagery-through-time-LINE.png' alt='航空影像序列图' width='100%' /><br />&nbsp;</p><hr /><p style='text-align:justify;'><span style='text-align:start;'>使用本网站或其中的内容，即表示您同意遵守</span><a target='_blank' href='https://www.oakgov.com/open-data-terms' rel='nofollow ugc noopener noreferrer'><u>使用条款</u></a><span style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size:17px;'><span style='text-align:start;'>。</span></span><br />&nbsp;</p>
