Topo-bathy lidar acquisition and processing in the Mariana Islands covering the islands of Aguijan, Rota, Saipan, and Tinian. These data are the hydro-flattened bare earth DEMs derived from the topo lidar coverage delivered in 500m x 500m tiles as 1m GeoTIFFs with no data values set to -999999 and bridges removed. Water bodies larger than two acres and streams wider than 100 feet were hydroflat...
马里亚纳群岛的拓扑地貌激光雷达采集与处理，涵盖了阿圭吉安、罗塔、塞班和提尼安等岛屿。本数据集为基于提供的拓扑激光雷达覆盖区域（以500米x500米瓦片形式交付，以1米GeoTIFF格式存储，数据值为-999999的空白处未设置数据，并移除了桥梁）所推导出的水文平滑裸地数字高程模型（DEM）。其中，大于两英亩的水域以及宽度超过100英尺的溪流均进行了水文平滑处理。
