Gridded Reference Graphic widget

Gridded Reference Graphic (GRG) allows an analyst to create grids for use in partitioning geographic areas of interest. Grids can be defined from a point or area and based on dimension, reference system, or time and speed. Gridded reference graphics can be used in a variety of operations, including search and rescue, cordon and search, and clearing operations.

Configure the Gridded Reference Graphic widget

This widget can be set to open automatically when an app starts. Click the Do not open this widget when the app starts button on the widget to turn on the option to open the widget automatically. (For widgets you need to add to the app first, you can make this setting after configuring the widget.)

1. Hover over the widget and click the Configure this widget button to open the configuration window.

   Note:

   If you need to add the widget to the app first, click a widget placeholder on the Widget tab. In the Choose Widget window that opens, select the widget and click OK.

2. To replace the widget icon with your own, click the Change widget icon button.

   A file explorer window appears, allowing you to select a local image file to use as the widget icon.

3. Use the Lock Settings toggle switch to set whether the settings will be locked when the app is deployed.
4. On the Grid tab, you can set the following:

   • Cell Outline color and transparency
   • Cell Fill color and transparency
   • Cell Shape
   • Cell Units
   • Grid Origin
   • Operational layer for results—Polygon feature layers from the current web map to which users can save results.

     Note:

     The list only includes layers from your organization. If the map uses polygon feature layers from another organization, they do not appear in the list.

5. On the Labels tab, you can set the following:

   • Label Style
   • Label Type
   • Label Direction
   • Label Origin

6. On the Reference System tab, you can set the default reference system:
   • Military Grid Reference System (MGRS)
   • U.S. National Grid (USNG)
   • Universal Transverse Mercator (UTM)

Define a grid from an area

Learn how to create grids by defining the area by dimension or by reference system.

Define a grid from an area by dimension

You can create a grid from a user-defined extent and a specified cell width and height, or number of horizontal and vertical cells.

1. Draw an area using either the polygon or extent interactive drawing tool.
2. Turn on the Define number of rows and columns toggle switch and enter values for # Horizontal Cells and # Vertical Cells to define the grid by a specific number of rows and columns, or leave it in the off position and enter values for Cell Width (x) and Cell Height (y).

   Note:

   • Units for cell width and height are set in the grid settings.
   • Only cell width is available when the cell shape is a hexagon.

3. Set a value for Grid Rotation.

   Note:

   Grid rotation units are degrees.

4. Optionally click the Settings button to change the settings available on the configuration dialog box.
5. Click Create GRG.
6. Delete cells from the grid by right-clicking a cell and clicking Delete.
7. Optionally click Publish after the GRG has been created to save it as a hosted feature layer.

Define a grid from an area by reference system

You can create a grid from a user-defined extent, based on a reference system.

1. Draw an area using the extent interactive drawing tool.
2. Select a grid size from the Grid Size drop-down list.
3. Turn the Clip Grid to GRG Area toggle switch on to limit the grid to only the extent drawn, or leave it off to include all grid cells the drawn extent intersects.
