What's new in ArcGIS Pro 3.1

See what's new and improved in ArcGIS Pro 3.1.

Video overview

This video was created by the ArcGIS Pro development teams and the product support teams to highlight new functionality in this release.

Highlights

The Highlights section includes featured new functionality.

Catalog layers

You can create and draw catalog layers in maps and scenes. A catalog layer is a collection of item references to local and shared datasets, layers, services, and workspaces from various work environments. The catalog layer is used to visualize and explore items as an organized group of layers based on the extent of a view. You can apply additional extent filters, symbolize footprint boundaries, and add field attributes to the dataset items to help you visualize layers of interest.

In this example, a catalog layer contains references to a shapefile, several images, and a geodatabase feature class.

Automatic resizing of layout elements

When you change the page size or orientation of a layout, you can automatically resize and reposition layout elements. Additionally, the new Duplicate Layout command creates a new layout at a different page size from an existing layout. All layout elements are preserved and can be automatically resized and repositioned.

Time-enabled scene layers

You can time-enable point, 3D object, or building scene layers to visualize 3D content temporally. For example, you can use the time slider to visualize building construction dates for a time range or apply a definition query to see which trees have been inspected within the past year. You can use this new capability to query, visualize, and analyze 3D content across desktop and web clients.

Scale-based label sizing

Scale-based label sizing allows you to smoothly change the text size of labels as you move across the scales of your map. This sizing helps to reduce visual density at smaller scales while retaining an appropriate relative size at larger scales. This new functionality reduces the need for multiple label classes, and can be used in 2D maps and vector tiles.

Magnifier window

In 2D maps, you can open a magnifier window to help with workflows such as seeing what content is visible at a larger scale, and using precise snapping when digitizing new features. Within the magnifier window, the active tool for navigation, selection, measurements, and editing is supported.

Reality Mapping

The tools and capabilities in the new ArcGIS Reality for ArcGIS Pro extension allow you to photogrammetrically correct and process drone and digital aerial imagery to produce high-fidelity 3D and 2D products. Wizards guide you through workspace and product generation workflows to create full-resolution DSMs, True Orthos, 2D DSM meshes, dense 3D point clouds, and 3D meshes with building facades. The tools and capabilities are described in three main categories:

• Reality workspace creation—Create workspaces for drone imagery, digital aerial imagery, and imagery from existing mosaic datasets.
• Block adjustment—Perform block adjustment, tie point generation, and add ground control points (GCPs) to a workspace.
• Reality product generation—Create photogrammetric products such as DSMs, True Orthos, 2D DSM meshes, 3D point clouds, and 3D meshes.

3D mesh with building facades generated from overlapping drone imagery.

Performance and productivity

Performance and productivity have been improved in ArcGIS Pro 3.1. Some examples are listed below; you can find more throughout the topic and elsewhere in the help.

Performance

• Processing speed for large-scale layer enrichments in Business Analyst may be up to three times faster than in ArcGIS Pro 3.0. See what's new in Business Analyst.

• When an editing tool is deactivated, you can set the default tool to be either the Explore tool or the Select tool . See what's new in editing.
• When you connect to an enterprise geodatabase, you can choose to list only objects owned by the connecting user. See what's new in geodatabases and databases.
• In ArcGIS Notebooks, you can drag and drop catalog, Contents pane, and history items into notebook cells. See what's new in Python.

Get started

• You can run context menu commands by typing the underscored letter on the command name. For example, on a layer context menu, type c to copy the layer, r to remove the layer, or a to open its attribute table.

Analysis and geoprocessing

General

• You can add a slider bar control to script tool parameters with a numeric data type (Long integer or Double) and Range filter by setting the parameter's controlCLSID property in the tool's ToolValidator class.

  

• The GPToolExecuteEvent in ArcGIS Pro SDK 3.1 for .NET allows you to track and take action when a tool is run in ArcGIS Pro. See What's New for Developers at 3.1.
• The size and position of geoprocessing tools opened in a floating window are stored for each tool in your user profile. When you close and reopen a tool, it opens at the same size and position as before.
