Overview

The Measure Tool is a sophisticated spatial measurement system that provides precise distance and area calculations with advanced bearing computation capabilities. Built on ArcGIS Measurement widget technology, this tool delivers professional-grade measurement functionality with real-time calculations, coordinate system transformation support, and intelligent bearing analysis for comprehensive spatial analysis and navigation applications.

Measurement Types

Advanced Line Measurement

• Precise Linear Distances: Calculates accurate measurements in kilometers using geodetic calculations
• Multi-Segment Line Support: Handles complex polylines with multiple segments and direction changes
• Real-Time Distance Display: Live measurement updates as you draw with immediate visual feedback
• Bearing Calculations: Automatically computes directional bearings between measurement points with degree precision
• Coordinate System Integration: Uses projectOperator for accurate spatial reference transformations

Professional Area Measurement

• Accurate Area Calculations: Computes enclosed areas in hectares using precise geodetic algorithms
• Complex Polygon Support: Handles intricate polygon geometries with multiple vertices and irregular shapes
• Immediate Area Computation: Real-time area calculations as you define polygon boundaries
• Memory Management: Intelligent cleanup of measurement graphics and event handlers for optimal performance
• Visual Feedback: Clear polygon highlighting and measurement display for enhanced user experience
