## Testing Upload

### Test 1: Upload via Web Interface

1. Go to http://localhost:8000
2. Click "Upload" tab
3. Drop file: `34.0478N_118.2349W_1650_test_raw.sub`
4. GPS auto-fills: **34.0478, -118.2349**
5. Click "Upload Files"
6. Go to "Map" tab
7. **Should see marker near UCLA**

### Test 2: Import via CLI

# Verify on map
curl http://localhost:8000/api/v1/query/captures | jq '.captures[] | {filename, latitude, longitude}'
```

### Test 3: Batch Directory Import

```bash
# Import all GPS-enabled files
./scripts/import_wardriving_data.py signatures/t-embed-rf/

# Check total
curl http://localhost:8000/api/v1/stats/summary | jq '.total_captures'
```

## Expected Results

After uploading all test files, you should see:

### On Map Tab
- **3-4 markers** in Los Angeles area
- **Green markers** (315 MHz)
- **Blue markers** (433.92 MHz)
- Clustered in West LA / UCLA / Downtown areas

### In Statistics Tab
```
Total Captures: 4
Unique Devices: 2
Frequency Distribution:
  - 315 MHz: 1 capture
  - 433.92 MHz: 3 captures
```

### In Database Query
```json
{
  "total": 4,
  "captures": [
    {
      "filename": "raw10.sub",

```

### List all GPS coordinates
```bash
curl -s http://localhost:8000/api/v1/query/captures | \
  jq '.captures[] | {filename, lat: .latitude, lon: .longitude}'

  }
}
```

## GPS Coordinate Ranges

### Valid Ranges
- **Latitude**: -90 to 90 (South to North)
  - Negative = Southern hemisphere
  - Positive = Northern hemisphere
  - 0 = Equator

- **Longitude**: -180 to 180 (West to East)
  - Negative = Western hemisphere
  - Positive = Eastern hemisphere
  - 0 = Prime Meridian (Greenwich)

### Los Angeles Reference
```
Los Angeles, CA:
  Latitude: ~34° N (positive)
  Longitude: ~118° W (negative)
  Full coords: 34.0522, -118.2437
```

## Troubleshooting

### Issue: Markers don't appear on map

**Check**:
1. Verify uploads succeeded: `curl http://localhost:8000/api/v1/query/captures`
2. Check GPS coordinates are valid (within range)
3. Refresh map page
4. Check browser console for errors

### Issue: Wrong location

**Check**:
1. Verify N/S/E/W in filename (W = negative lon)
2. Check coordinate order (lat first, lon second)
3. Validate coordinate ranges

### Issue: Can't see captures on map

**Solution**:
1. Zoom out to see Los Angeles area
2. Look for marker clusters (multiple captures at same location)
3. Click Statistics tab to verify uploads
