Use, Analysis and Visualization of Geodata

Introduction to CODAP – The Common Online Data Analysis Platform

CODAP (Common Online Data Analysis Platform) is a powerful web-based tool designed for data analysis and visualization. It allows users to import, explore, and interpret geospatial datasets, making it a valuable resource for educators and students.

📌 Why use CODAP?

• Interactive and web-based – No installation required.
• Supports real-world data exploration – Useful for climate, environmental, and spatial analysis.
• Easy visualization tools – Generates graphs, tables, and box plots.

Session Structure

🔹 Input Phase: Participants observe and learn how to use CODAP for data analysis.
🔹 Example Walkthrough: Guided exploration of geospatial datasets.
🔹 Hands-On Practice: Participants import and analyze data independently.

Activity 1 – Analyzing Forest Fire Data

🔥 Dataset: Fire events recorded between June 5 and July 23, 2020, in Tucson, Arizona.
📡 Key Variable: Aerosol Optical Depth (AOD), a measure of air pollution caused by wildfire smoke.

Steps to Explore the Dataset:

1️⃣ Download the dataset → Fire Data CSV
2️⃣ Open CODAP and import the dataset.
3️⃣ Explore Variables: Identify relationships between fire intensity and AOD levels.
4️⃣ Visualize Data: Create scatter plots, histograms, and box plots to observe trends.
5️⃣ Interpret Findings: What impact did the wildfire have on atmospheric conditions?

🔗 NASA’s Fire Information for Resource Management System (FIRMS) provides real-time fire data: FIRMS Fire Map

Activity 2 – Earthquake Data Analysis

🌍 Dataset: Global earthquake records.
📊 Key Variables: Magnitude, depth, and location of earthquakes.

Steps to Explore the Dataset:

1️⃣ Download the dataset → Earthquake Data CSV
2️⃣ Import it into CODAP and explore different earthquake events.
3️⃣ Visualize Patterns:

• How do earthquake depth and magnitude relate?
• Which regions experience the most seismic activity?
  4️⃣ Discuss Findings: How can data analysis support disaster preparedness?

Applying CODAP in Education

✅ Supports inquiry-based learning – Encourages students to think like scientists.
✅ Improves data literacy – Develops skills in statistics, visualization, and interpretation.
✅ Enhances geospatial analysis – Integrates real-world climate and environmental datasets.
