    • The present invention uses data from several sources to determine lines-of-sight between nodes in a FSO network. The present invention provides a three-dimensional neighborhood modeling system that uses aerial image data, Digital Elevation Models, U.S. street map data and address data to automatically map the placement of nodes within a neighborhood or other geographical area. Method for creating the 3-Dimensional, House and Tree Maps used in the line-of-sight processing are also disclosed. A House Map in the present invention identifies houses in an area of consideration, and a Tree Map in the present invention identifies trees in an area of consideration. A 3-Dimensional Map in the present invention provides an elevation for every pixel for the area under consideration, whereby the elevation is adjusted for the height of trees, houses and other objects.
    • 本发明使用来自多个源的数据来确定FSO网络中的节点之间的视距。 本发明提供一种三维邻域建模系统,其使用空中图像数据,数字高程模型,美国街道地图数据和地址数据来自动映射邻域或其他地理区域内的节点的位置。用于创建三维 在视线处理中使用的House和Tree Maps也被公开。 本发明中的房屋地图识别考虑区域中的房屋,并且本发明中的树形图识别考虑区域中的树木。 本发明的三维图提供了所考虑的区域的每个像素的高度,由此根据树木,房屋和其他物体的高度来调节高度。
