GeoIntel Kempen — Demo Scenarios v1.0

Demo scenarios guide development toward portfolio-ready workflows.

Demo 1 — Building Detection + GRB QA/QC

Goal

Show the complete GeoAI loop: raster imagery → AI detections → geospatial output → official reference validation.

Workflow

1. Create project: Geel Building Detection QA.
2. Select or draw area in Geel.
3. Upload a georeferenced aerial/orthophoto raster.
4. Fetch GRB buildings for the area or use OSM fallback.
5. Run object detection for buildings.
6. Convert detections to geospatial polygons.
7. Run QA/QC against GRB buildings.
8. Show precision, recall, F1, mean IoU.
9. Display TP/FP/FN on map.
10. Export detections and QA findings as GeoJSON/CSV.

Recruiter value

Demonstrates Rasterio, tiling, YOLO/PyTorch, GeoPandas/Shapely, PostGIS, QA metrics and official geodata validation.

Demo 2 — Vegetation Segmentation

Goal

Show segmentation/mask-to-vector workflow.

Workflow

1. Select area around Mol or Kasterlee.
2. Upload raster or use sample imagery.
3. Run segmentation or NDVI-based threshold.
4. Polygonize vegetation masks.
5. Calculate green area and fragmentation.
6. Export vegetation polygons.

Demo 3 — Vector Change Detection

Goal

Show change analysis before full raster AI change detection is implemented.

Workflow

1. Select two building/reference layers for the same area.
2. Run vector change detection.
3. Classify added, removed and modified features.
4. Show change statistics and map overlays.

Demo 4 — Raster Workbench

Goal

Show professional raster handling.

Workflow

1. Upload GeoTIFF.
2. Inspect metadata.
3. Clip to area.
4. Generate preview.
5. Generate tiles.
6. Export clipped raster.

Demo 5 — Vector Workbench

Goal

Show core GIS operations.

Workflow

1. Upload GeoJSON/GPKG.
2. Inspect metadata.
3. Clip to area.
4. Buffer roads.
5. Intersect buffers with green/water/building layers.
6. Export result.

Demo readiness checklist

• Demo datasets present or documented.
• No fake results.
• Every result is exportable.
• Every map layer is inspectable.
• Every long operation has job status.
• QA output can be explained in one minute.
