GIS II

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...

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...
