Measure distances and areas

You can easily measure distances and areas on your map using the Measure tool. The Measure tool allows you to draw a single-segment or multisegment line to measure a linear path, or a shape to measure a specific area. You can also use the Measure tool to find the coordinates of any point on the map. You can also change the default units of measurement while you use the tool.

Add the Measure tool to the ArcGIS Maps web part

You must add the Measure tool to the ArcGIS Maps web part before you can use it.

  1. Edit the page and place the ArcGIS Maps web part into edit mode.
  2. Click the Configure button Configure to display the configuration options.
  3. From the list of configuration options, click Tools and choose Map tools.
  4. Click the Add button (+) from the top of the panel.
  5. Expand the esriMapsSharePointX category to display available tools.
  6. Check the Measure check box and click Add.

    The Measure tool appears in the list of Map tools.

  7. Click OK to exit the configuration options.
  8. Click OK on the ArcGIS Maps web part properties to save your changes and exit edit mode.
  9. Save your page.

Measure a distance

Measure distances on the map by drawing a line to specify a linear path.

  1. On the Map tools toolbar, click the Measure tool.
  2. Click the Distance button Measure distance.
  3. Click two or more points on the map to draw a line. When you are finished drawing, double-click to complete the line.

    The result of your distance measurement appears at the bottom of the Measure tool.

    Note:

    Depending on the distance and location of your measurement, the line you drew may be curved. This is because the Measure tool must take into account the natural curvature of the earth to calculate the shortest path between two points. The curve you see is called a geodesic curve. Lines and shapes drawn using geodesic curves more accurately represent length, direction, and position everywhere on the surface of the earth.

  4. To change the distance units, choose a new unit of measurement from the drop-down menu.

    The measurement result updates to reflect the new units.

  5. To measure another distance, click on the map and draw a new line.

    The new line replaces the previous measurement line on the map, and the measurement result updates to reflect the new distance.

Measure an area

Measure areas on the map by drawing a shape to specify an area.

  1. On the Map tools toolbar, click the Measure tool.
  2. Measure area button Click Area.
  3. Click three or more points on the map to draw a shape. Double-click to complete the shape.

    The result of your area measurement appears at the bottom of the Measure tool.

    Note:

    Depending on the distance and location of your measurement, the line you drew may be curved. This is because the Measure tool must take into account the natural curvature of the earth to calculate the shortest path between two points. The curve you see is called a geodesic curve. Lines and shapes drawn using geodesic curves more accurately represent length, direction, and position everywhere on the surface of the earth.

  4. To change the area units, choose a new unit of measurement from the drop-down menu.

    The measurement result updates to reflect the new units.

  5. To measure another area, click on the map and draw a new shape.

    The new shape replaces the previous measurement shape on the map, and the measurement result updates to reflect the new area.

Display coordinates for a point

Display longitude and latitude coordinates for a point on the map by clicking a specific location.

  1. On the Map tools toolbar, click the Location tool.
  2. Click the map at the location for which you want to get coordinates.

    The coordinates of the point appear at the bottom of the Measure tool.

  3. To change the units, choose a new unit of measurement from the drop-down menu. Choose from Decimal Degrees or Degrees, Minutes, Seconds (DMS).

    The result updates to reflect the new units.

  4. To view coordinates for another location, click a different point on the map.

    The result updates to reflect the new location.

Pan the map while measuring

You may find that what you want to measure is not completely contained within the current extent of the map; for example, a street or parcel may extend beyond what is visible.

To move the map as you're measuring, while still maintaining the cumulative total distance or area, hold down the left mouse button (or the equivalent navigation) and drag to pan the map in the direction you want. Resume measuring by clicking the map with the left mouse button.

Close the Measure tool

Close the Measure tool by clicking the Close (X) button on the tool.

When you close the tool, all measurement graphics are cleared from the map.
