Measurement

Measure distances and areas directly on the map. The measurement tools provide accurate calculations using geodesic formulas that account for Earth's curvature.

1. Click the ruler icon in the analysis toolbar
2. Choose Distance or Area mode
3. Click on the map to start measuring

1. Select Distance mode
2. Click on the map to set the starting point
3. Click additional points to add segments
4. View the total distance and individual segments
5. Double-click to finish, or click Clear to start over

1. Select Area mode
2. Click on the map to place polygon vertices
3. Continue clicking to define the area boundary
4. View the calculated area and perimeter
5. Double-click to finish, or click Clear to start over

Toggle between metric and imperial units:

• Metric — Kilometers (km), meters (m), hectares (ha), square kilometers (km²)
• Imperial — Miles (mi), feet (ft), acres, square miles (mi²)

The measurement panel shows:

• Total distance or area
• Perimeter (for area measurements)
• Individual segment lengths
• Click any segment to see its length

Measurements use geodesic calculations that account for:

• Earth's curvature (not flat plane calculations)
• Accurate results for any distance
• Precision suitable for most mapping needs

• Zoom in for more precise point placement
• Measurements are temporary — they don't create permanent features
• Click Clear to remove the current measurement and start over
