The ruler on a field's map gives you a quick distance or area. For a layer's values inside a shape, [draw a zone](/home/fieldagent-web/view-and-analyze/zones-and-zone-statistics.md) instead. *** ## Measure on the map {% stepper %} {% step %} #### Open the measure tool Click a field in the **Fields** panel, then click the ruler icon

that appears on the map. The ruler icon at the top-right corner of the map

{% endstep %} {% step %} #### Choose what to measure, and the unit Choose **Distance**

or **Area**

. Then pick an imperial or metric unit from the **Unit** menu. The measure panel: Distance and Area tabs and the Unit menu set to Feet

All units in the Unit menu

| Measure | Units | | -------- | ----------------------------------------------------------------------------------------------------------- | | Distance | Inches, Feet, Yards, Miles, Centimeters, Meters and Kilometers | | Area | Acres, Sq. Inches, Sq. Feet, Sq. Yards, Sq. Miles, Hectares, Sq. Centimeters, Sq. Meters and Sq. Kilometers |

{% endstep %} {% step %} #### Draw the line or shape Click the map to place each point. Double-click the last point to end a line. For an area, double-click the last corner, or click the first corner, to close the shape.

The measure tool open in the top-right corner of the map with the Distance tab selected and Unit set to Feet; a yellow line crosses the field with the label 890.91 ft

The measurement then appears as a label on the map. {% endstep %} {% step %} #### Close the tool Click the close icon

on the measurement panel. {% endstep %} {% endstepper %} {% hint style="info" %} No number while you click? That's expected. The tool shows nothing until you finish the line or shape, so double-click the last point. {% endhint %} *** ## Related pages {% content-ref url="/pages/Jgi1Im9DL0dsUKMeiPFH" %} [Zones and zone statistics](/home/fieldagent-web/view-and-analyze/zones-and-zone-statistics.md) {% endcontent-ref %} {% content-ref url="/pages/hFBVUsKMPfZeBiEZKD2u" %} [Map layers](/home/fieldagent-web/view-and-analyze/map-layers.md) {% endcontent-ref %} --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://support.senterasensors.com/home/fieldagent-web/view-and-analyze/measure-a-distance-or-an-area.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
