🏷️ Labels: Geopandas, Geospatial, Python, Data Processing
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal

The goal of this session was to implement geospatial data processing using GeoPandas, focusing on loading, manipulating, and analyzing geospatial data.

Key Activities

  • Loading JSON Data: A guide was provided for downloading JSON data from a URL and loading it into a GeoDataFrame using GeoPandas.
  • Downloading and Extracting Shapefiles: Python code examples were shared for downloading ZIP files containing shapefiles and loading them into a GeoDataFrame.
  • Handling SSL Errors: Instructions were given on bypassing SSL certificate verification when downloading files with the requests library, along with a security best practices warning.
  • Specifying Extraction Directories: Solutions for extracting ZIP files to specified directories were discussed.
  • Spatial Join and Overlay: Techniques for performing spatial joins and curated overlays on GeoDataFrames were implemented, including sorting columns by unique value counts.

Achievements

  • Successfully implemented methods for loading and processing geospatial data using GeoPandas.
  • Developed functions for spatial joins and curated overlays, enhancing data analysis capabilities.

Pending Tasks

  • Further exploration of security best practices when handling SSL certificates in production environments.
  • Optimization of data manipulation techniques for larger datasets.
