📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal

The goal of this session was to resolve errors encountered when using the ogr2ogr tool to process GeoJSON files, specifically focusing on driver errors and size limitations.

Key Activities

• Resolving Driver Error: Modified the ogr2ogr command to include the -f GeoJSONSeq option to handle GeoJSON files properly.
• Handling Large Files: Addressed issues with processing large GeoJSON files by modifying environment variables to increase the maximum size limit for features.
• Python Integration: Provided a Python code snippet for setting environment variables to prevent the ‘GeoJSON object too complex’ error.
• Feature Extraction: Used ogr2ogr to extract the last 100 features from a GeoJSON file by skipping a set number of features.

Achievements

• Successfully resolved the driver error and size limitation issues, enabling smoother processing of GeoJSON files with ogr2ogr.
• Integrated solutions into Python scripts for automated handling of large GeoJSON files.

Pending Tasks

• Further testing of the implemented solutions in different environments to ensure robustness and compatibility with various GeoJSON datasets.
