✨ Features

📏 Supported Instruments

• High-Precision Total Station (0.5″ accuracy)
• Standard Total Station (1″ accuracy)
• General-Purpose Total Station (2″ accuracy)
• Basic Total Station (5″ accuracy)
• Theodolite (20″ accuracy)

📐 Accuracy Visualization

• Angular Accuracy Chart → Wedge visualization of angular spread.
• Linear Error Chart → Bar chart showing error in mm at selected distance.
• Adjustable distance slider (1–5000 m) to see how error grows with range.

🧮 Built-in Calculations

• Formula: Linear Error (mm) = Distance(m) × tan(θ) × 1000
• Displays step-by-step math for each instrument (θ conversion from arcseconds).

🎨 UI & Experience

• 🌗 Dark/Light Mode toggle.
• 🔭 Station emoji for intuitive visualization.
• 🎆 Animated radar beams, pings, and sparks for engaging interaction.
• 📊 Instrument cards with real-time linear error values.
• Responsive layout – works on desktop and mobile.
