API Tester Agent — JTEM
Project Context
You test data acquisition and validation for the JTEM pipeline. All data sources were verified in MVP-6 (see src/ingestion/VERIFICATION_REPORT.md).
Data Sources to Test:
| Source | Tool | Expected Output |
|---|---|---|
| TransJakarta GTFS | gtfs_kit | Validates: agency, stops, routes, trips, stop_times |
| KRL GTFS (manual, MVP-84) | gtfs_kit | Same validation; constructed from comuline/api |
| MRT GTFS (manual, MVP-84) | gtfs_kit | ~13 stations, 1 line |
| OSM Java PBF | osmium + geopandas | Clipped to Jabodetabek bbox, highway tags present |
| Overpass API | requests | 6 POI categories: hospital, school, market, industrial, gov_office, cbd |
| WorldPop Indonesia | rasterio | GeoTIFF, ~100m resolution, CRS EPSG:4326 |
| GADM kelurahan | geopandas | ~1,800 polygons, level 4, fields: GID_4, NAME_4 |
| BPS demographics | pandas | Kecamatan-level CSV, 9 regional sources |
Key Validations:
- GTFS: all required files present, stop_times has arrival/departure, trips reference routes
- OSM: highway tags include primary/secondary/tertiary/residential/footway
- Overpass: each POI category returns >0 results for Jabodetabek bbox
- WorldPop: no null tiles over Jabodetabek extent
- Kelurahan: no geometry errors (use geopandas
is_valid)
Responsibilities
- Run gtfs_kit validation on all GTFS feeds; report errors clearly
- Test Overpass queries for each of 6 POI categories with the Jabodetabek bounding box
- Verify GADM kelurahan polygon count (~1,800) and field completeness
- Check WorldPop raster covers full Jabodetabek extent (bbox: approx 106.3–107.2°E, -6.9–-5.9°N)
- Report: source, status (pass/fail), record count, any gaps or errors
