LAB 6

The objective of this lab is to build a spatial model of site suitability for corn cultivation using the model builder. Site suitability of corn cultivation is dependent on land use, slope, and soil. The model builder uses various tools, explained below, that are able to rank the best land and the worst land for corn cultivation. This land is then able to be mapped. 



To get to the final map the model builder is needed. In the model builder, the proper shape files need to be added. These include the landuse shapefile, the slope shapefile, and the soils shapefile. Once these are added, the shape files need to be converted to raster. This is done by dragging the feature to raster tool into the model builder, then filling out the tool for separately for landuse, slope, and soils. This creates an output that needs to be reclassified. Reclassifying ranks the best to worst features for each landuse, slope, and soil. This is done by separately dragging the reclassify tool into the model builder, and filling out the tool for for landuse, slope, and soil. Once an output is created for all three features, the weighted overlay tool needs to be dragged in to the model builder. The weighted overlay tool uses the ranks from the reclassify tool, and combines them will the other features to create an overall rank of the data for the whole focus area. This is raster data that can be mapped. The map is shown above. The map Highlights the best to worst areas for corn cultivation.

Lab 2 GEOG 337 Due 2/25/2018 Jeffrey Hessburg This lab entails accurately georeferencing a historic 1878 map Eau Claire. Georeferencing is a tough task to do because there is a lot of room for error. Essentially georeferencing is giving raster data a spatial location. Using the georeferencing tool in ArcMap, it can be done. The first task in the lab is to add the data and answer why you entered this data is a certain order. the reason for this is because the raster data has to be given a coordinate system, it will automatically be added to the first layer put in ArcMap. The next step is to actually georeference the map. To do this we use the already referenced base-map, and map of the roads. We must find points on the 1887 map of Eau Claire that correspond to the points on the base-map and road map. This was the hardest challenge. The 1887 map has different some different roads, and road names so it is difficult to find points that correspond. It is also important to find p...

Lab 3 GIS 2 2/25/2018 Jeffrey Hessburg The goal of the lab is to create map illustrating a drainage basin. A drainage basin, otherwise known as a watershed, is an area where all water from surrounding surfaces converge. These are areas are determined by analyzing the topography of an area then determining the lowest points and where water will flow. The watershed is bordered from surrounding watersheds by ridges and high points that separate flow. It is important to understand and visualize watersheds to understand where water is coming from.  This Lab has us determine where the watershed boundaries in Adirondack Park by following three steps: data processing, followed by data processing. then finally watershed delineation. Collecting the data consisted of logging on to gis.ny.gov and downloading a file called Andirondak Park Boundary.  The file needs to be unzipped in the correct folder, then added to ArcCatalog. The first thing that needs to be added to ArcMap is th...

Curtis GEOG337 S18 Jeffrey Hessburg Lab 1 This lab first asked what Geographic Coordinate System(GCS), Projected Coordinate System(PCS ), and Projection was used in a provided map. To find this you go to the desired layer's properties, and check the source. It is important to know this information, especially if you are adding new data to the map. You do not what to have data that is displayed in two different coordinate systems, the data would not be accurately represented.  The next things asked were what ArcCatalog is, and what is the difference between that and ArcMap. It is very important to know what ArcCatalog is, and how to use it. It is essential for organizing, understanding, and uploading data to ArcMap.  The next steps were to look at attribute tables for different layers. Attribute tables are key to understanding the data in each layer. It is also very important to know how to manipulate the data correctly to answer certain questions. The question was...
