Note: Currently only displays units in [m]/[km].

Show measure tools

Displays measure tools in the upper right corner. Measurements appear only when this control is open.

  • Click to start measuring
  • Continue clicking to continue measurement
  • Double-click to end measurement

Note:
- When you change measurement type or units, the previous measurement is removed from the map.
- If the control is closed and then re-opened, the most recent measurement is displayed.
- A measurement can be modified by clicking and dragging on it.

Length

Get the spherical length of a geometry. This length is the sum of the great circle distances between coordinates. For multi-part geometries, the length is the sum of the length of each part. Geometries are assumed to be in ‘EPSG:3857’.

  • Metric (m/km)
  • Feet (ft)
  • Miles (mi)
  • Nautical miles (nmi)

Area

Get the spherical area of a geometry. This area is calculated assuming that polygon edges are segments of great circles on a sphere. Geometries are assumed to be in ‘EPSG:3857’.

  • Square Meters (m²)
  • Square Kilometers (km²)
  • Square Feet (ft²)
  • Square Miles (mi²)
  • Acres (acre)
  • Hectare (ha)

Show debug

Displays debug information in the upper right corner. This can be useful for debugging or validating a data source.

  • Zoom displays current zoom level of the map.
  • Center displays the current longitude, latitude of the map center.

Tooltip

  • None displays tooltips only when a data point is clicked.
  • Details displays tooltips when a mouse pointer hovers over a data point.
