Measurement widget

The Measurement widget allows you to measure the area of a polygon, length of a line, or find the coordinates of a point.

Note:

For the most accurate results, use Web Mercator for the geographic type of spatial references. For other spatial references or complex polygons, a simplification process will be applied to deal with the distortion caused by spatial projections or complicated polygons.

Caution:

You may notice a difference in buffer operation from the Near Me widget. This is because the Near Me widget uses a Euclidean buffer (Planar) by default and has an option for a geodesic buffer. The Measurement widget, however, defaults to a geodesic buffer with no other option.

Configure the Measurement widget

This widget can be set to open automatically when an app starts. To enable this feature, click the Open this widget automatically when the app starts button Open this widget automatically when the app starts on the widget, which turns it dark green.

  1. Hover over the widget and select Configure this widget button Configure this widget to open the configuration properties dialog box.
  2. The configuration window for this widget appears.

    Measurement configuration

    The Default Area Unit parameter allows you to configure the unit of measure for polygon measurements. The options are as follows:

    • Acres
    • Sq Miles
    • Sq Kilometers
    • Hectares
    • Sq Yards
    • Sq Feet
    • Sq Meters

    The Default Length Unit parameter allows you to configure the unit of measure for line and polyline measurements. The options are as follows:

    • Miles
    • Kilometers
    • Feet
    • Meters
    • Yards
    • Nautical Miles

  3. Click OK to close the window when you're finished.

Use the Measurement widget

Click the Measurement widget icon to open it.

Point measurements

  1. Click the Point measurement button Point measurement and click a point on the map.

    The Measurement widget displays the coordinates for the point in degrees (decimal). To change the coordinate display format to degrees/minutes/seconds, change the selection in the Degrees drop-down menu to DMS.

Polyline measurements

  1. Click the Polyline measurement button Polyline measurement.
  2. Draw a polyline on the map by clicking two or more points.
  3. Double-click to finish drawing the polyline.

    The Measurement widget displays the total length of the polyline using the defined Default Length Unit. To change the length unit, select the applicable unit of measure from the Milesdrop-down menu.

Polygon measurements

  1. Click the Polygon measurement button Polygon measurement.
  2. Draw a polygon on the map by clicking three or more points.
  3. Double-click to finish drawing the polygon.

    The Measurement widget displays the total area of the polygon using the defined Default Area Unit. To change the area unit, select the applicable unit of measure from the Acres drop-down menu.
