# 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.
