Module 1.3 - Data Quality - Assessment


Below are the steps I used to complete the assessment of the road network quality.

·         Used Clip Layer tool to isolate only roads within the Grid for both the Centerlines shapefile and the     TIGER Roads shapefile.

·         Used the Intersect tool to clip the Centerlines and TIGER clipped shapefiles to the Grid.

·         Used Tabulate Intersection tool to calculate the length of each segment of both shapefiles that occurred   in each grid  section.

        I then exported the attribute tables to Excel to complete all calculations and readded the excel sheet back into my map to create the choropleth.

A Little Bit About Me

Our family on our girls' first cave tour in Eureka Springs, AR - March 2022 My name is Jessica Williamson.

I hope GIS can merge ...

Module 3 - Cartographic Design

The goal of this module was to create a map showing the public schools in Ward 7 of Washington D.C. by using methods that comply with Gestalt's Principles. I created this map using ArcGIS Pro. I tried to keep the focus of the map on Ward 7 and specifically, on the schools in that area. I labeled each school using an icon of differing sizes to denote the education level of each school, (i.e. elementary, middle, high schools). When choosing the colors of the map I tried to keep the important features in brighter colors while not overpowering the map. While designing the layout I tried to use all available space to include the inset map and other map elements without cluttering the map frame and keeping the focus on the important features and information.
