Find a location in a defined coordinate system in Portal for ArcGIS

Summary

Finding a place on a map based on coordinates in a specific spatial reference can be done using the Location tool in the Map Viewer, which is included in both ArcGIS Online, and ArcGIS Enterprise 10.8.1 or higher.  This tool is designed for both online and offline use, providing flexibility in different operational environments. Notably, this method does not require geocoding services. The tool can locate a point based on coordinates in the coordinate system of the basemap. Below is a step-by-step guide through this process. 

Procedure

1. Access the Map Viewer.
   1. Log in to the Portal for ArcGIS or ArcGIS Online. 
   2. From the Home page, click the Map page to access the tool.
2. In Map Viewer, configure a custom basemap in a certain coordinate system that represents a spatial reference for layers you published.
   1. Click Basemap on the Contents (dark) toolbar.
   2. Click Current basemap and add your layers from the bottom of the pane. 
3. Open the Location tool.
   1. On the Settings (light) toolbar, click on Map tools  .
   2. Choose Location.

4. Click the Expand control on the right side to display options.

5. Click the Input coordinate (pencil icon) to provide the coordinates.  
   1. In the Input coordinate window, select BASEMAP to use the coordinate system of the current basemap. 
   2. In the Input coordinate box, type the coordinate values. For example, 790354.917, 306958.376 in Pulkovo 1942(58) / Stereo70, the coordinate system of the basemap used for this article. To ensure better precision, include more significant digits after the decimal point. 

6. Click Convert to locate the point.

After converting the coordinates, the tool places a small circle on the resulting location on the map, as shown in the image below.
