Description

Session Goal

The session aimed to resolve errors encountered when processing GeoJSON files using the ogr2ogr tool, focusing on driver errors and handling large file sizes.

Key Activities

• Resolving Driver Error: Identified and fixed an error with the ogr2ogr tool by using the -f GeoJSONSeq option for correct file handling.
• Handling Large Files: Addressed issues with large GeoJSON files by setting an environment variable to increase the maximum size limit for features.
• Python Integration: Provided a Python code snippet to set the environment variable, preventing ‘GeoJSON object too complex’ errors during conversion.
• Feature Extraction: Demonstrated how to extract the last 100 features from a GeoJSON file using ogr2ogr with specific command options.

Achievements

• Successfully resolved the driver error and size limitations for GeoJSON files in ogr2ogr.
• Enabled efficient processing of large GeoJSON files by modifying environment variables and using Python scripts.

Pending Tasks

• Further testing of the solutions in different environments to ensure robustness and compatibility.
