Description

Session Goal

The session aimed to implement and refine geospatial data processing techniques using Python and the GeoPandas library.

Key Activities

• Loading JSON Data: A step-by-step guide was followed to download JSON data from a URL and load it into a GeoDataFrame using GeoPandas.
• Downloading and Extracting Shapefiles: Python code was utilized to download a ZIP file containing shapefiles and extract them to a specified directory, ensuring proper file management.
• Handling SSL Certificate Errors: Techniques to bypass SSL certificate verification in Python were discussed, with an emphasis on security best practices.
• Spatial Join and Overlay Functions: Implemented spatial join using gpd.sjoin() and a curated overlay function to analyze geospatial data, including sorting columns by unique value counts.

Achievements

• Successfully loaded and processed geospatial data into GeoDataFrames.
• Implemented secure file download and extraction processes.
• Developed and tested spatial join and overlay functions for data analysis.

Pending Tasks

• Review and optimize the overlay function for performance improvements.
• Explore additional geospatial data sources for further analysis.
