Knopf Presents Project Findings at the Minnesota GIS/LIS Conference
In mid-October, Jeff Knopf presented at Minnesota’s GIS/LIS Conference in Bemidji. Jeff spoke about his involvement in a pilot project with the State of Minnesota’s 3D Geomatics DEM Hydro-modification Subgroup to investigate the value of legacy breachlines and newly acquired high resolution digital elevation model (DEM) data for usefulness in hydro-modification. Considerable money has been spent on the creation of the legacy breachlines and, with the acquisition of new DEMs for the State of Minnesota, many stakeholders are concerned as to whether money spent on breachlines required for hydro-modification was lost. Hydro-modification is a necessary step to prepare elevation models for analysis, such as, identification of where to place best management practices, flood analysis, measurement of nitrogen and phosphorus transport, to name a few. The pilot project found that the legacy breachlines are an essential dataset for hydrologic modeling and terrain analysis.
