Goals:
The goal of this first introductory lab
was to familiarize ourselves with working with various data sets in Arc GIS and learn the basics of digitizing
and manipulating these data sets. This was done by acting the part of a Clear
Vision Eau Claire Intern, digitizing the lot sites for the Eau Claire Confluence Project, a
new development between local developers, UW-Eau Claire and the Eau Claire
Regional Arts Center. I was tasked to prepare base maps containing all relevant
data surrounding the Eau Claire Confluence and organize these maps in a clear
and concise manner.
Methods:
The first thing I did was create a blank
geodatabase, renamed for the Eau Claire Confluence, and a new featured class
labeled Proposed Site into this geodatabase. From there, I imported the Eau Claire
County Coordinate System from a census feature, giving the new feature class
the appropriate coordinate system. From there, I opened the up the proposed
site feature class along with the base imagery and parcel area datasets. Using
a provided aerial image of the Confluence Project and by using the parcel area
lot lines as an outline, I digitized a polygon feature for the Proposed Site
Feature Class. Using a PLSS Quarter-Quarter dataset from the city, I learned
about the township and range system for determining the location of a plot
specifically for the Confluence Project. The legal outline used to assist in the digitizing
and the location identification was taken from the City of Eau Claire,Wisconsin’s mapping website.
With the newly digitized proposed site area, I constructed six data
frames to show the relation of the Confluence Project to various geographic
features. A Civil Divisions data frame, showing the Confluence Project in relationship
to the municipality type of the surrounding area. A Census Boundaries data
frame, showing the relationship to the surrounding population density of Eau Claire.
A PLSS Features data frame, showing the relative PLSS Quarter Quarter
divisions. An Eau Claire Parcel data frame, showing the surrounding lot
parcels. A Zoning data frame, showcasing the zoning class and distribution of
the surrounding area. And one final data frame, Voting Districts, to show the
surrounding voting districts. These data frames were all constructed to be
cartographically pleasing, with scale markers in all data frames, and constructed
into a singular map with legends for all the necessary data.
Results:
This lab project resulted in the creation of the map seen below. From
creating this map, I learned of the process of digitizing data and creating as aesthetically
pleasing and concise map to show relevant data related to a desired feature class.
I also learned of the legal descriptions involved in creating such a parcel
taken from a city parcel system.
