Summary

  • Complete ETL pipeline for geospatial data extraction and processing
  • New spatial_data module with extractor architecture for spatial datasets
  • GeoParquet output format with PostGIS database integration for metadata logging

Key Features

  • Data Sources: MN Geospatial Commons (vector & raster support)
  • File Formats: GeoParquet (primary), Shapefile, CSV+WKT
  • Database Integration: PostGIS schema for extraction logs and metadata catalog
  • CLI Commands: list-datasets, test, extract with flexible output options
  • Performance: Sub-second to 15-second extractions with efficient compression

Production Validation

  • Vector dataset (protected_areas): 1,731 features in 0.8s → 2.9 MB GeoParquet
  • Raster dataset (groundwater_recharge): 201,264 features in 14.5s → 5.6 MB GeoParquet

Architecture

  • Parallel module design (separate from time-series sensor data)
  • Reuses 85% of existing rtgs-lab-tools infrastructure
  • Native spatial operations with GeoPandas GeoDataFrames
  • Extractor pattern for acquiring external spatial data

Files Added

  • Core infrastructure: extractor.py, base classes, registry system
  • Data sources: MN Geospatial Commons extractor
  • Database: PostGIS schema and logger
  • CLI: Complete command set for spatial data operations
  • Documentation: README, architecture docs, decision matrices

Test Plan

  • Vector data extraction tested with protected_areas dataset
  • Raster data extraction tested with groundwater_recharge dataset
  • CRS transformation validation (EPSG:26915 → EPSG:4326)
  • GeoParquet output format validation
  • PostGIS database logging validation
  • CLI command functionality verified
  • End-to-end pipeline validation
