Changing the layout in GIS, specifically in ArcGIS Pro, involves adjusting the size and properties of your map composition. Here's how you can do it:
-
Activate the Layout: Make sure the layout you want to modify is the currently active view in ArcGIS Pro.
-
Access Page Setup: Navigate to the "Layout" tab in the ArcGIS Pro ribbon. Within the "Page Setup" group, find and click the "Size" drop-down list.
-
Choose Resize Option: Decide whether you want the elements within your layout (e.g., maps, legends, text) to automatically resize along with the layout. If so, check the "Resize Elements" option. This helps maintain visual consistency.
-
Select a New Size: From the "Size" drop-down list, select a new layout size that meets your needs. You can choose from a variety of standard sizes or define a custom size.
Detailed Steps and Considerations:
-
Custom Sizes: If the desired size isn't available in the list, you can define a custom page size. You'll typically specify the width and height in units like inches or centimeters.
-
Orientation: You can also adjust the orientation of the layout (portrait or landscape) within the Page Setup options.
-
Margins: Consider the margins of your layout. Margins define the empty space around the content of your layout. Adjusting margins can affect the overall appearance and readability of your map.
-
Scale Considerations: When resizing, especially with "Resize Elements" checked, be aware of how the map scale is affected. Significantly changing the size might require adjustments to the map scale to maintain appropriate levels of detail.
-
Layout Elements: After resizing, review all layout elements (north arrows, scale bars, text, legends, etc.) to ensure they are appropriately sized and positioned relative to the new layout size. You might need to manually adjust their properties and locations.
-
ArcGIS Pro Help: For more detailed information and troubleshooting, refer to the official ArcGIS Pro documentation: Change a layout.
By following these steps, you can effectively change the layout size and properties in GIS to create visually appealing and informative maps.
