Introduction

As a GIS professional, you've likely encountered the frustration of discovering that your carefully crafted map legend has changed after exporting it from ArcGIS Pro. This issue can be particularly puzzling, especially when you've taken the time to customize the legend to meet your specific needs. In this article, we'll delve into the reasons behind this phenomenon and provide you with practical solutions to ensure that your legend remains intact after export.

Understanding the Issue

When you export a map from ArcGIS Pro, the software generates a new image that reflects the current state of the map. However, this process can sometimes result in unexpected changes to the legend, including its location, size, and even the inclusion of unwanted elements. One common issue is the appearance of the map frame (named layers) in the exported PNG's legend. This can be particularly problematic if you've carefully designed your map to exclude these elements.

Why Does This Happen?

There are several reasons why the legend may change after export:

Legend settings: ArcGIS Pro allows you to customize the legend settings, including the location, size, and orientation. However, these settings may not be preserved when exporting the map.
Map frame (named layers): As mentioned earlier, the map frame (named layers) can sometimes appear in the exported PNG's legend. This is often due to the way ArcGIS Pro handles the map frame when exporting the map.
Layer order: The order in which layers are stacked in the map can affect the appearance of the legend. If a layer is placed above or below another layer, it may be included in the legend or excluded altogether.
Symbolization: The symbolization of layers can also impact the legend. If a layer has a complex symbol, it may be displayed differently in the legend than it is on the map.

Solutions to the Problem

While the reasons behind the legend changes after export may seem complex, there are several solutions you can try to ensure that your legend remains intact:

Use the "Export Map" tool: When exporting a map from ArcGIS Pro, use the "Export Map" tool instead of the "Export Data" tool. This will help preserve the legend settings and ensure that the map frame (named layers) are not included in the exported PNG's legend.
Customize the legend settings: Before exporting the map, make sure to customize the legend settings to meet your specific needs. This includes setting the location, size, and orientation of the legend.
Use a legend template: ArcGIS Pro allows you to create a legend template that can be applied to your map. This can help ensure that the legend appears consistently across different exports.
Use the "Legend" tool: The "Legend" tool in ArcGIS Pro allows you to create a legend that is separate from the map. This can help prevent the legend from changing after export.
Use a different export format: If you're experiencing issues with the PNG export format, try exporting the map in a different format, such as JPEG or TIFF.

Best Practices for Working with Legends in ArcGIS Pro

To avoid the frustration of discovering that your legend has changed after export, follow these best practices:

Create a legend template: As mentioned earlier, create a legend template that can be applied to your map. This will help ensure that the legend appears consistently across different exports.
Customize the legend settings: Before exporting the map, make sure to customize the legend settings to meet your specific needs.
Use the "Export Map" tool: When exporting a map from ArcGIS Pro, use the "Export Map" tool instead of the "Export Data" tool.
Use a separate legend: Consider creating a separate legend that is not tied to the map. This can help prevent the legend from changing after export.
Test your map: Before exporting the map, test it to ensure that the legend appears as expected.
