Jeffrey Hessburg GIS II Lab 4 11 March 2018 Pedestrian Networks at UWEC This lab aimed at going through the process of network analysis. First a network dataset was to be created in order to solve the question: How has the Garfield Avenue construction project affected pedestrian traffic at UWEC? Initially, a map was to be downloaded from the project website. Next the map had to be georefrenced to the World Topographic Map, ESRI, 2018. Otherwise the calculations from the rout would not be accurate.  The ESRI courses Preparing for Network Analysis and Network Analysis using ArcGIS taught how to set up network datasets using the data provided in the lab folder. The data provided was two possible paths leading from the north end of the student walking bridge, to the front of of Phillips Hall. Using network analysis, flags could be placed on the route to calculate the total distance needed to be traveled. This was done desperately for each route. The calculations show t...

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...

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...
