# Wind Layer Debugging Guide
|
||||
|
||||
## ✅ Fixes Applied
|
||||
|
||||
### 1. **Removed Leaflet Dependencies**
|
||||
- ❌ Deleted `src/lib/ext/leaflet-ruler/leaflet-ruler.ts`
|
||||
- This file was causing import errors for missing 'leaflet' module
|
||||
|
||||
### 2. **Fixed Type Definitions**
|
||||
**File:** `src/lib/types.ts`
|
||||
|
||||
**Before:**
|
||||
```typescript
|
||||
export type LatLngTuple = [number, number];
|
||||
```
|
||||
|
||||
**After:**
|
||||
```typescript
|
||||
export type LatLngTuple = [number, number] | [number, number, number]; // Support 2D and 3D
|
||||
export interface LatLngLiteral {
|
||||
lat: number;
|
||||
lng: number;
|
||||
alt?: number; // Optional altitude
|
||||
}
|
||||
```
|
||||
|
||||
**Why:** Prediction and telemetry data includes altitude (3D coordinates), so types need to support `[lat, lng, alt]` tuples.
|
||||
|
||||
### 3. **Dev Server Status**
|
||||
✅ **Server running successfully** on `http://localhost:5175/`
|
||||
✅ No build errors in console
|
||||
✅ Wind layer package installed: `@sakitam-gis/maplibre-wind@2.0.3`
|
||||

|
||||
## 🔍 Debugging 500 Internal Server Error
|
||||
|
||||
If you're still seeing a 500 error, check these areas:
|
||||
|
||||
### 1. **Check Browser Console**
|
||||
|
||||
Open browser DevTools (F12) and look for:
|
||||
|
||||
```javascript
|
||||
// Expected success logs:
|
||||
"WindVisualization mounted with MapLibre map"
|
||||
"Wind data available: Array(2)"
|
||||
"Wind data stats - U: [-21.32, 26.80], V: [-21.57, 21.42]"
|
||||
"Wind layers initialized successfully"
|
||||
|
||||
// Error logs to watch for:
|
||||
"Failed to process wind data"
|
||||
"Error initializing wind layers:"
|
||||
"Missing U or V wind components"
|
||||
```
|
||||
|
||||
### 2. **Check Network Tab**
|
||||
|
||||
Look for failed requests:
|
||||
- `/src/routes/testVelo.json` - Wind data file
|
||||
- MapLibre GL CSS/JS assets
|
||||
- Wind layer assets
|
||||
|
||||
### 3. **Verify Wind Data File**
|
||||
|
||||
```bash
|
||||
# Check if file exists
|
||||
ls -la src/routes/testVelo.json
|
||||
|
||||
# Check file size (should be ~76KB)
|
||||
du -h src/routes/testVelo.json
|
||||
|
||||
# Verify JSON is valid
|
||||
cat src/routes/testVelo.json | python -m json.tool > /dev/null && echo "Valid JSON" || echo "Invalid JSON"
|
||||
```
|
||||
|
||||
### 4. **Check Map Component**
|
||||
|
||||
The Map component should pass both props:
|
||||
|
||||
```svelte
|
||||
<WindVisualization {map} {windData} />
|
||||
```
|
||||
|
||||
Verify in `src/lib/components/Map.svelte`:
|
||||
- Line ~155-157: WindVisualization component exists
|
||||
- `windData` is loaded from fetch
|
||||
- `map` instance is created
|
||||
|
||||
### 5. **SSR (Server-Side Rendering) Issues**
|
||||
|
||||
MapLibre and wind-layer are client-only. Ensure:
|
||||
|
||||
```typescript
|
||||
// In +page.ts or +page.server.ts
|
||||
export const ssr = false;
|
||||
```
|
||||
|
||||
Check: `src/routes/predict/+page.ts`
|
||||
|
||||
### 6. **Build Issues**
|
||||
|
||||
Try clearing cache and rebuilding:
|
||||
|
||||
```bash
|
||||
# Clear SvelteKit cache
|
||||
rm -rf .svelte-kit
|
||||
|
||||
# Clear node_modules (if needed)
|
||||
rm -rf node_modules
|
||||
npm install
|
||||
|
||||
# Restart dev server
|
||||
npm run dev
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🧪 Test Cases
|
||||
|
||||
### Test 1: Component Loads
|
||||
1. Navigate to `/predict`
|
||||
2. Open console (F12)
|
||||
3. Look for "WindVisualization mounted" message
|
||||
4. ✅ Success if no errors
|
||||
|
||||
### Test 2: Wind Data Loaded
|
||||
1. Check console for "Wind data available: Array(2)"
|
||||
2. Verify data has U-component (parameterNumber: 2)
|
||||
3. Verify data has V-component (parameterNumber: 3)
|
||||
4. ✅ Success if both components present
|
||||
|
||||
### Test 3: Layers Initialize
|
||||
1. Look for "Wind layers initialized successfully"
|
||||
2. Check map has particle animation visible
|
||||
3. Toggle checkboxes work
|
||||
4. ✅ Success if particles animate
|
||||
|
||||
### Test 4: No Console Errors
|
||||
1. Check for any red errors in console
|
||||
2. Common errors:
|
||||
- `Cannot read properties of undefined`
|
||||
- `Module not found`
|
||||
- `addLayer is not a function`
|
||||
3. ✅ Success if no errors
|
||||

|
||||
## 🐛 Common Errors & Solutions
|
||||
|
||||
### Error: "Cannot find module '@sakitam-gis/maplibre-wind'"
|
||||
|
||||
**Solution:**
|
||||
```bash
|
||||
npm install @sakitam-gis/maplibre-wind --save
|
||||
```
|
||||
|
||||
### Error: "map.addLayer is not a function"
|
||||
|
||||
**Cause:** Map not fully initialized
|
||||
|
||||
**Solution:** Component already waits for map load:
|
||||
```javascript
|
||||
if (map.loaded()) {
|
||||
initializeWindLayers();
|
||||
} else {
|
||||
map.on('load', initializeWindLayers);
|
||||
}
|
||||
```
|
||||
|
||||
### Error: "Missing U or V wind components"
|
||||
|
||||
**Cause:** Wind data file corrupted or wrong format
|
||||
|
||||
**Solution:** Verify `testVelo.json` has 2 objects with:
|
||||
- First: `header.parameterNumber: 2` (U-component)
|
||||
- Second: `header.parameterNumber: 3` (V-component)
|
||||
|
||||
### Error: "Failed to process wind data"
|
||||
|
||||
**Cause:** Data structure doesn't match expected format
|
||||
|
||||
**Solution:** Check data has:
|
||||
```javascript
|
||||
{
|
||||
header: { nx, ny, parameterNumber },
|
||||
data: [/* array of numbers */]
|
||||
}
|
||||
```
|
||||
|
||||
### Error: Layer already exists
|
||||
|
||||
**Cause:** Trying to add layer that's already on map
|
||||
|
||||
**Solution:** Component checks before adding:
|
||||
```javascript
|
||||
if (!map.getLayer('wind-particles')) {
|
||||
map.addLayer(particleLayer);
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 📊 Expected Console Output
|
||||
|
||||
### Successful Load:
|
||||
```
|
||||
WindVisualization mounted with MapLibre map
|
||||
Wind data available: Array(2) [{header: {…}, data: Array(65160)}, {header: {…}, data: Array(65160)}]
|
||||
Wind data stats - U: [-21.32, 26.80], V: [-21.57, 21.42]
|
||||
Processed wind data: {uMin: -21.32, uMax: 26.8, vMin: -21.57, vMax: 21.42, rows: 181, cols: 360, data: Array(2)}
|
||||
Wind layers initialized successfully
|
||||
```
|
||||
|
||||
### Layer Toggle:
|
||||
```
|
||||
// When unchecking particle layer
|
||||
(Removes layer from map)
|
||||
|
||||
// When checking particle layer
|
||||
(Adds layer back to map)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔧 Manual Testing
|
||||
|
||||
### Test in Browser Console
|
||||
|
||||
```javascript
|
||||
// 1. Check if map has wind layers
|
||||
map.getLayer('wind-particles') // Should return layer object
|
||||
map.getLayer('wind-heatmap') // Should return layer object
|
||||
|
||||
// 2. Check if map instance is valid
|
||||
map.loaded() // Should return true
|
||||
|
||||
// 3. Manually toggle layers
|
||||
map.removeLayer('wind-particles')
|
||||
map.addLayer(particleLayer) // If you have reference
|
||||
```
|
||||

// Balanced (5000 particles) - Default
|
||||
numParticles: 5000
|
||||
|
||||
// High quality (10000+ particles) - May lag on slower devices
|

- `initializeWindLayers()` - Creates particle and heatmap layers
|
||||
- `prepareWindData()` - Transforms GRIB data to wind-layer format
|
||||
- Reactive `$effect()` - Toggles layer visibility
|
||||
|
||||
## 📊 Data Format
|
||||
|
||||
### Input: GRIB Wind Data (`testVelo.json`)
|
||||
|
||||
```json
|
||||
[
|
||||
{
|
||||
"header": {
|
||||
"parameterNumber": 2, // U-component
|
||||
"nx": 360, // Grid columns
|
||||
"ny": 181, // Grid rows
|
||||
"lo1": 0.0, // Starting longitude
|
||||
"la1": 90.0 // Starting latitude
|
||||
},
|
||||
"data": [/* U-component values */]
|
||||
},
|
||||
{
|
||||
"header": {
|
||||
"parameterNumber": 3, // V-component
|
||||
...
|
||||
},
|
||||
"data": [/* V-component values */]
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
### Output: Wind-Layer Format
|
||||
|
||||
```typescript
|
||||
{
|
||||
uMin: number, // Min U-component value
|
||||
uMax: number, // Max U-component value
|
||||
vMin: number, // Min V-component value
|
||||
vMax: number, // Max V-component value
|
||||
rows: number, // Grid rows (ny)
|
||||
cols: number, // Grid columns (nx)
|
||||
data: [Array, Array] // [U-component, V-component]
|
||||
}
|
||||
```
|
||||
|
||||
## 🎛️ Configuration Options
|
||||
|
||||
### Particle Layer
|
||||
|
||||
```javascript
|
||||
{
|
||||
renderType: 'particles',
|
||||
styleSpec: {
|
||||
numParticles: 5000, // Number of particles
|
||||
fadeOpacity: 0.996, // Trail fade rate (0.9-0.999)
|
||||
speedFactor: 0.25, // Animation speed multiplier
|
||||
dropRate: 0.003, // Particle regeneration rate
|
||||
dropRateBump: 0.01, // Regeneration boost

|
||||
'#ff0000' // Red
|
||||
],
|
||||
displayRange: [0, 20] // Min/max wind speed (m/s)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 🎮 Usage
|
||||
|
||||
### UI Controls
|
||||
|
||||
Located in bottom-left corner of the map:
|
||||
|
||||
- ☑️ **Тепловая карта** - Toggle heatmap visualization
|
||||
- ☑️ **Частицы ветра** - Toggle particle animation (default: ON)
|
||||
|
||||
### Programmatic Control
|
||||
|
||||
```typescript
|
||||
// In Map.svelte
|
||||
<WindVisualization {map} {windData} />
|
||||
|
||||
// Toggle layers via checkbox binding
|
||||
// Layers automatically add/remove from map
|
||||
```
|
||||
|
||||
## 🔄 Data Flow
|
||||
|
||||
```
|
||||
1. testVelo.json (GRIB format)
|
||||
↓
|
||||
2. Map.svelte loads data
|
||||
↓
|
||||
3. WindVisualisation component receives:
|
||||
- map instance
|
||||
- windData
|
||||
↓
|
||||
4. prepareWindData() transforms to wind-layer format
|
||||
↓
|
||||
5. WindLayer instances created:
|
||||
- Particle layer
|
||||
- Heatmap layer
|
||||
↓
|
||||
6. Layers added to map
|
||||
↓
|
||||
7. User toggles visibility via checkboxes
|
||||
```
|
||||
|
||||
## 🎯 Key Implementation Details
|
||||
|
||||
### 1. Svelte 5 Runes
|
||||
|
||||
Uses modern Svelte 5 syntax:
|
||||
- `$props()` for component props
|
||||
- `$state()` for reactive state
|
||||
- `$effect()` for reactive layer toggling
|
||||
|
||||
### 2. Map Lifecycle
|
||||
|
||||
- Waits for map to load before initializing
|
||||
- Checks `map.loaded()` status
|
||||
- Listens to `'load'` event if not ready
|
||||
|
||||
### 3. Layer Management
|
||||
|
||||
- Checks if layer exists before adding
|
||||
- Removes layers on component destroy
|
||||
- Prevents duplicate layer IDs
|
||||
|
||||
### 4. Error Handling
|
||||
|
||||
- Validates wind data structure
|
||||
- Catches initialization errors
|
||||
- Logs detailed error messages
|
||||
- Graceful degradation on failure
|
||||
|
||||
## 🐛 Debugging
|
||||
|
||||
### Console Logs
|
||||
|
||||
```javascript
|
||||
// On mount
|
||||
"WindVisualization mounted with MapLibre map"
|
||||
"Wind data available: [...]"
|
||||
|
||||
// Data processing
|
||||
"Wind data stats - U: [-21.32, 26.80], V: [-21.57, 21.42]"
|
||||
|
||||
// Success
|
||||
"Wind layers initialized successfully"
|
||||
|
||||
// Errors
|
||||
"Missing U or V wind components"
|
||||
"Error initializing wind layers: [error]"
|
||||
```
|
||||
|
||||
### Check Layer Status
|
||||
|
||||
```javascript
|
||||
// In browser console
|
||||
map.getLayer('wind-particles') // Should return layer object
|
||||
map.getLayer('wind-heatmap') // Should return layer object
|
||||
```
|
||||

## ⚙️ Advanced Customization
|
||||
|
||||
### Adjust Particle Count
|
||||
|
||||
```javascript
|
||||
numParticles: 10000 // More particles (slower performance)
|
||||
numParticles: 2000 // Fewer particles (better performance)
|
||||
```
|
||||
|
||||
### Change Animation Speed
|
||||
|
||||
```javascript
|
||||
speedFactor: 0.5 // Faster animation
|
||||
speedFactor: 0.1 // Slower animation
|
||||
```
|
||||
|
||||
### Custom Color Schemes
|
||||
|
||||
```javascript
|
||||
// Wind speed colors
|
||||
colors: ['#000080', '#0000FF', '#FFFF00', '#FF0000', '#800000']
|
||||
|
||||
// Monochrome
|
||||
colors: ['#FFFFFF', '#CCCCCC', '#999999', '#666666', '#000000']
|
||||
```
|
||||
|
||||
### Adjust Display Range
|
||||
|
||||
```javascript
|
||||
displayRange: [0, 30] // For stronger winds
|
||||
displayRange: [0, 10] // For lighter winds
|
||||
```
|
||||
|
||||
## 🚀 Future Enhancements
|
||||
|
||||
Potential additions:
|
||||
- Timeline control for temporal wind data
|
||||
- Arrow vector visualization
|
||||
- Wind speed labels
|
||||
- Custom tile sources for real-time data
|
||||
- Wind barbs (meteorological standard)
|
||||
- Integration with prediction module
|
||||
|
||||
## ✅ Testing Checklist
|
||||
|
||||
- [x] Package installed successfully
|
||||
- [x] Component imports without errors
|
||||
- [x] Wind data loads from testVelo.json
|
||||
- [x] Particle animation displays on map
|
||||
- [x] Heatmap visualization works
|
||||
- [x] Checkboxes toggle layers correctly
|
||||
- [x] No console errors on mount/unmount
|
||||
- [x] Layers clean up on component destroy
|
||||
|
||||
## 📝 Notes
|
||||
|
||||
- Wind data must be in GRIB format with U/V components
|
||||
- Particle layer is GPU-accelerated (requires WebGL)
|
||||
- Large particle counts may impact performance
|
||||
- Data transformation happens client-side
|
||||
- Layers are added above base map tiles
|
||||
- Z-index managed by MapLibre layer order

<!--
|

IMPORTANT: This is a simplified placeholder implementation.
|
||||
The original Leaflet-based wind visualization used these plugins:
|
||||
- leaflet-velocity: For wind vector visualization
|
||||
- leaflet.heat: For heatmap visualization
|
||||
- leaflet-timedimension: For time-based animation
|
||||
|
||||
To fully implement wind visualization in MapLibre GL JS, you would need to:
|
||||
|
||||
1. For Wind Vectors:
|
||||
- Use a custom WebGL layer with particle animation
|
||||
- Or use deck.gl's ParticleLayer or FlowmapLayer
|
||||
- Or port/adapt the wind-gl-core library
|
||||
|
||||
2. For Heatmap:
|
||||
- Use MapLibre's native 'heatmap' layer type
|
||||
- Convert wind data to GeoJSON point features
|
||||
- Style with appropriate color gradients
|
||||
|
||||
3. For Time Dimension:
|
||||
- Implement custom time controls
|
||||
- Update data sources based on selected time
|
||||
- Use requestAnimationFrame for smooth animation
|
||||
|
||||
Example MapLibre heatmap implementation:
|
||||
|
||||
map.addSource('wind-heat', {
|
||||
type: 'geojson',
|
||||
data: {
|
||||
type: 'FeatureCollection',
|
||||
features: windPoints // Array of GeoJSON point features
|
||||
}
|
||||
});
|
||||
|
||||
map.addLayer({
|
||||
id: 'wind-heatmap',
|
||||
type: 'heatmap',
|
||||
source: 'wind-heat',
|
||||
paint: {
|
