BIOSOLIDS TRACKING SYSTEM

摘要

A biosolids computer tracking system (10) monitors the quantity and quality of biosolids deposited on a plot of land. Global positioning system technology (20) is used to determine the land coordinates of the boundary of the plot of land for accurate area calculation in order to determine the loading per unit area of biosolids including metals deposited on the plot. The system includes the ability to display (14, 18) superposed topographic and digitized photographic imagery (34) of the plot with textual annotation
