What This Document Is
This document outlines a practical exercise for Northwest Missouri State University’s GEOG 32364 Image Interpretation and Analysis course. Specifically, it details the steps required to create dot density maps using ArcGIS Online, focusing on racial proportion data within the contiguous United States. It’s a guided assignment designed to build skills in spatial data handling and visualization.
Why This Document Matters
This exercise is intended for students enrolled in GEOG 32364 who need to gain hands-on experience with ArcGIS Online. It’s used to apply theoretical concepts of cartography and spatial analysis to a real-world dataset. Successful completion demonstrates proficiency in data loading, joining attributes, and map styling within a GIS environment.
Common Limitations or Challenges
This document provides a workflow for a specific task within ArcGIS Online. It does not cover broader GIS principles or advanced mapping techniques. Students will still need to understand the underlying concepts of proportional symbol mapping and data representation to effectively interpret and analyze the results. It assumes a basic familiarity with the ArcGIS Online interface.
What This Document Provides
The full document includes:
* Detailed, step-by-step instructions for loading shapefiles and CSV data into ArcGIS Online.
* Specific guidance on joining tabular data to spatial data based on state abbreviations.
* Instructions for changing map styles to create effective dot density visualizations.
* File names for required datasets (USA_States_Contiguous.zip and Racial_Proportion_State.csv).
* Naming conventions for resulting map layers.
This preview *does not* include the actual map creation process, the completed maps, or detailed explanations of cartographic principles. It only describes the assignment’s structure and requirements.
