Kordil EPS Integration - Excavator Positioning System
🎯 Perfect Data Preparation Tool for Kordil EPS
The Kordil XYZ Viewer is an excellent support tool for preparing and validating terrain data for the Kordil EPS (Excavator Positioning System). Use this viewer to:
- Visualize & Verify: Check your design surface data before loading into EPS
- Clean & Edit: Remove outliers, unwanted points, and data errors using lasso and polygon delete tools
- Quality Control: Validate elevation accuracy and data coverage with profile analysis
- Fill Gaps: Use surface interpolation (Kriging, Linear IDW, or Nearest Neighbor) to complete missing areas in your design model
- Profile Analysis: Extract cross-sections to verify excavation grades and slopes
- Export Refined Data: Save cleaned, validated XYZ files ready for excavator guidance systems
🏗️ Construction Workflow: Survey → Process in XYZ Viewer → Validate & Clean → Export to Kordil EPS → Guide Excavator with Precision

💡 Pro Tips
- Use vertical scale to exaggerate subtle terrain features
- Adjust custom color range to highlight specific elevation zones
- Use profile lines to extract cross-sections for detailed analysis
- Export edited data to preserve your point cloud modifications
- Use polygon interpolation to fill gaps in survey data
- Toggle top view (T key) for accurate map-like navigation
🔧 Technical Specifications
- Technology: WebGL-based 3D rendering (Three.js)
- Browser Support: Chrome (recommended), Edge (recommended), Firefox (good), Safari (acceptable) - latest versions
- File Format: XYZ ASCII text files (comma, tab, or space-delimited)
- Coordinate Systems: Local coordinates, UTM, geographic coordinates
- Performance: Optimized for datasets up to millions of points
- Export Format: XYZ text file with preserved coordinate precision
📊 Performance & File Size Limits
Recommended Limits for Optimal Performance:
- Optimal: Up to 1 million points (smooth interaction, fast rendering)
- Good: 1-5 million points (may experience minor lag on rotation/zoom)
- Acceptable: 5-10 million points (slower performance, requires powerful GPU)
- Maximum File Size: Typically 500MB-1GB (depends on browser memory limits)
- System Requirements: Modern GPU with WebGL support, 8GB+ RAM recommended for large datasets
⚠️ What to Do If Your File Exceeds Limits
If your point cloud dataset is too large or causing performance issues:
- Option 1: Decimate/Downsample Your Data
- Reduce point density before loading (e.g., keep every 2nd or 3rd point)
- Use external tools to thin out dense point clouds
- Maintain representative data coverage with fewer points
- Option 2: Split Into Smaller Sections
- Divide large datasets into geographic regions or tiles
- Load and analyze sections individually
- Process area-by-area for targeted analysis
- Option 3: Filter by Area of Interest
- Extract only the region you need to analyze
- Remove points outside your study area
- Focus on critical elevation zones
- Option 4: Contact Kordil for Enterprise Solutions
- For massive datasets (10M+ points)
- Custom high-performance visualization solutions
- Dedicated processing and analysis tools
- Visit Kordil EPS Solutions for professional services
💡 Pro Tip: For best performance, close other browser tabs and applications when working with large datasets.
Browser Performance:
• Chrome/Edge (Recommended): Best WebGL performance, handles large datasets smoothly
• Firefox: Good compatibility but may experience slower rendering with 3M+ points due to WebGL implementation differences. Use Chrome/Edge for optimal experience with large files.
• Safari: Acceptable performance, works well for small-medium datasets
