🏷️ Labels: Geopandas, Matplotlib, Data Visualization, Python, Geojson
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal

The session focused on enhancing the visualization of GeoJSON data using Python libraries GeoPandas and Matplotlib.

Key Activities

  • Developed a Python script for loading and plotting GeoJSON data using GeoPandas, integrating additional data sources and visualizing with Matplotlib.
  • Refactored the GeoDataFrame plotting code to optimize performance, simplifying the color mapping process.
  • Adjusted color mappings and hatch patterns in the geospatial data visualization to improve clarity and aesthetics.
  • Implemented solutions for displaying hatch patterns in Matplotlib legends using the Patch class.
  • Revised plotting logic to ensure hatch patterns are visible by plotting them first and overlaying translucent face colors.

Achievements

  • Successfully created a comprehensive script for visualizing GeoJSON data with enhanced aesthetics, including color and hatch pattern adjustments.
  • Improved the clarity and effectiveness of geospatial data visualizations.

Pending Tasks

  • Further testing of the plotting script with different datasets to ensure robustness and adaptability.
  • Exploration of additional aesthetic features and optimization techniques for large datasets.
