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 β€˜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.
