<br />AARON M. MIELKE <br />GIS Specialist <br /> <br />Experience <br /> <br />Aaron's primary areas of expertise are geographic information systems (GIS) <br />technology and data analysis. At Barr, Aaron works on environmental impact <br />statement (EIS) reports, permits, and studies. He also creates maps and <br />datasets/shapefiles using data analysis procedures or by digitizing information <br />from aerial photographs or field-colleted data. Prior to joining Barr, Aaron <br />worked for the Minnesota Department of Agriculture, where he specialized in <br />analyzing data sets using ArcGIS software, designing maps, and developing new <br />data collection methods. <br /> <br />Aarons's work for Barr clients includes: <br /> <br />Education <br /> <br />· Developing a GIS procedure as part of EIS reports and studies for Polymet <br />Mining Corporation. The procedure, created to calculate the surface area of <br />stock piles at several intervals over a 20-year period, included creating <br />triangular irregular network (TIN) models of stock piles and converting the <br />data to grids for 5-, 10-, 15-, and 20-year intervals. Work included calculating <br />stock-pile cover areas and creating shapefiles to show surface area in 40 ft. <br />contours for each pile. A script was also developed to batch process several of <br />the steps. Work was completed using ArcMap with 3D analyst and spatial <br />analyst extensions and Microsoft Excel. <br /> <br />· Creating datasets and figures for an EIS mining permit for Minnesota Steel <br />Industries. Work included analyzing county-parcel data. The figures give the <br />client the ability to identify land ownership within the project area. Using <br />ArcMap, each parcel was classified based on a combination of class codes <br />and ownership types. The new dataset included attributes that allowed for the <br />creation of maps to show ownership classified into several categories defined <br />by the client. <br /> <br />· Executing GIS procedure as part of a tailings discharge evaluation for Iron <br />Ore Company ~f Canada. Work included creating TINs and grids for <br />underwater volume calculations. TINs were created to represent the surface of <br />the tailings discharge starting at the surface of the lake and assuming a 10 <br />percent slope. The existing grid of the lake bathymetry was used as the <br />bottom surface. Once the grids were created the volume between the two <br />surfaces was used to calculate the underwater tailings volume. This was done <br />using ArcMap with 3D analyst and spatial analyst extensions. <br /> <br />Graduate Certificate, GIS, University of Wisconsin Madison, 2005 <br /> <br />B.S., Natural Resources, University of Wisconsin Madison, 2002 <br /> <br />247810 <br /> <br />Barr Engineering Company <br />
