Alternative Sources of Accurate Agriculture TopographyCedar Valley Innovation LLC, Waterloo, IowaProblem Statement• The goal is to measure the relative accuracy of alternate methods to create topographic data of agriculture fields for water flow and related analysesProposed Solutions• Utilize data gathered from an actual field to find the most accurate topographical results to show water flow analysis and soil relocation analysisMajor Outcomes1. Collect data from an actual field in commercial farm production-Compare the differences in topography results -Show the differences, if any in resulting water flow analysis-Show the differences, if any in soil relocation2. Design a workflow diagram that a modern grower or crop advisor can use to duplicate the process on his or her own landBenefit to Client• To improve the effectiveness of water management practices and decrease soil erosion through accurate topography dataObjectives1. Understand alternate methods of gathering topographic data-LIDAR Data-Public Domain sources-Drone overflights and analysis-Data gathered by yield monitoring system2. Compare the accuracy, logistics, and cost of the alternate methods3. Demonstrate the complete data and workflow to complete a water flow analysisMethods• TSM 433 - Utilize SMS Software to analyze data from yield monitor• Use drone overflights to create 3-D topographical map of a field• Use of public domain sources to gather data• TSM 324 – Analyze LIDAR dataScope• Methods of measuring topography data on row crop field• Analyze accuracy of elevation throughout the field and be able to conduct a water flow analysis
