摘要： A composite code assigned to each manhole of a sewer system in a geographical region is associated with an x-y location of the manhole on a digitized geographical map of the region containing a representation of the sewer system including manholes plotted thereon. The composite code is stored in a memory of a computer. Other information regarding each of the manholes is entered into corresponding records stored in the memory of the computer. The composite code is utilized as a link between the record for each manhole and the x-y location of each manhole on the digitized map. Utilizing a computer mouse, an x-y location associated with a location of a manhole on a display of the digitized map containing the sewer system is selected. In response to the selection, the record associated with the selected manhole is retrieved from the computer's memory utilizing the composite code. The retrieved record is displayed on the display.

摘要翻译： 分配给地理区域中的下水道系统的每个人孔的综合代码与该区域的数字化地理图上的人孔的x-y位置相关联，该地理区域包含下图所示的下水道系统，其中包括人孔。 复合代码存储在计算机的存储器中。 关于每个人孔的其他信息被输入到存储在计算机的存储器中的相应记录中。 复合码用作数字地图上每个人孔的记录和每个人孔的x-y位置之间的连接。 利用计算机鼠标，选择与包含下水道系统的数字化地图的显示器上的人孔位置相关联的x-y位置。 响应于选择，使用复合代码从计算机的存储器检索与所选择的人孔相关联的记录。 检索到的记录显示在显示屏上。
