The value calculated is shown in the attribute table. In the Calculate Geometry dialog box, select the option Use coordinate system of the data frame, and select the desired units as the requirement.Right-click the field header, and select Calculate Geometry.
The tool can calculate coordinate values, lengths, and areas, depen. The same issue also occurs when calculating the length of line features and perimeters of polygon features. Do one of the following to open the Calculate Field dialog box: Click Calculate. In ArcMap, when using the Calculate Geometry tool to calculate areas of a feature layer, the output in the attribute table is different compared to the areas calculated by the Field Calculator and the Add Geometry Attribute tools. Click the column containing the values you want to calculate. Tip: You can also perform these steps from the table in Map Viewer Classic. For example, a name like Area_sqkm is suitable to store areas in square kilometers. The Calculate Geometry tool allows you to access the geometry of the features in a layer. From the layer's item page, click the Data tab to show the table. Create a Double field, and assign a name with no spaces, and no more than 10 characters in length.
Refer to the following article, Select a suitable map projection or coordinate system, for more information. The following are possible solutions to the issue.Īssign a more suitable projection to the ArcMap data frame A straight line drawn on the map is the bearing to fly a plane or sail a boat from the starting point to the destination, however this severely distorts distance and area. Online basemaps use the 'Web Mercator' projection, but the 'Mercator' projection is used for navigation. When using the Calculate Geometry tool to perform calculations on basemaps, inaccurate results are returned. Problem: The Calculate Geometry tool produces incorrect results for basemaps Description
