GIS I Lab 1: Base Data

Goal and Background:

The purpose of this assignment was to show the different features surrounding the area of the confluence project. The confluence project is a county wide project that will provide student housing and create a new art center in downtown Eau Claire. It is intended to break ground in 2014. The goal of this assignment was to show the location of different features of the city that surround the confluence project.
Methods:

The first thing that had to be done was to create a geodatabase for the proposed site of the confluence project.  Once the geodatabase was made, a feature class for the proposed site needed to be added. This allowed that specific feature class to be applied easily to all the maps. Once the feature class was made, we had to digitize the site so it was easier to identify. After the site had been digitized, new individual maps had to be made to highlight different features around the area of the confluence project.

The first map made dealt with the PLSS or public land survey system. A new data frame was created in order to keep all related information together. A basemap of the world was added in order to locate the proposed site and see the surrounding area. The PLSS section feature class was added to the map from both the county and city data. Once that was added, the PLSS quarter quarter sections were added to the map from the county and city data. This allowed for a more specific area of where the proposed site was located.

 Once the site was identified, the next step was to build a very brief legal description for each of the two parcels. Once the legal description was made, the next step was to build multiple relevant maps of the area surrounding the confluence project.

The first map was dealing with civil divisions. The first step was inserting a new data frame to keep all the information together. Then the civil divisions feature class was added to the map along with the proposed site feature class. This showed what civil division the confluence project was located in. The next map showed where the different census boundaries were located. A new data frame was inserted for this data. The block and tract groups feature class was then added to the map. The tracts had to be moved on top of the block group in order to see the both of them. The block group was then set to represent the population of 2007 for the City of Eau Claire. The next data frame needed was with the data for the City of Eau Claire. Once the new data frame was made, the parcel area, centerlines and water feature classes were added to the map. An aerial map was added in order to more easily identify the different parcel areas.

The next map that was made was for the different zoning classes. A data frame was made for Zoning and the zoning areas feature class was then added to the map. Due to the large amounts of different zone classes, the assignment called for the classes to be grouped based on similar symbols. Since the data was narrowed down, it made the map much easier to understand for the viewer.

The last map dealt with the different voting districts for the City of Eau Claire. A new data frame was inserted, and the voting district feature class was added to the map. The districts were labeled so it would be known what zone the confluence project would be located in.

Results:

Figure 1.1 This is a compilation of all the base maps for the area surrounding the Confluence Project.
 
There is no significant pattern with all these different maps. There is something interesting that is happening in the same block group as the confluence project. The zoning map shows that it is mainly central district zoning where the confluence project is located. Even though it is not strictly residential, there is still a fairly large population living in that particular block group.
