Pixel Editor
New in ArcGIS Image Analyst, the Pixel Editor provides a suite of tools to interactively manipulate pixel values for raster and imagery data. It allows you to edit an individual pixel or groups of pixels at once. The types of operations that you can perform depends on the data source type of your raster dataset.

Dynamic feature binning
When you work with large point feature classes stored in a relational database management system (RDBMS), you can aggregate the features into dynamic polygon bins when the feature class is added as a layer to a map or scene. The feature class must first be enabled for binning with the Enable Feature Binning geoprocessing tool. You can then display the features as bins at smaller scales while still drawing the point features at larger scales, where their display is manageable and understandable. Each bin represents all features within its boundaries and can be symbolized to reflect feature count or a different summary statistic.
Parcel fabric
The parcel fabric is a comprehensive framework for managing, editing, and sharing parcel data in ArcGIS Enterprise.

The parcel fabric can be maintained in both a single-user deployment and a multiuser deployment. In a single-user deployment, the parcel fabric is edited and maintained in a file geodatabase. In a multiuser deployment, the parcel fabric is created in an enterprise geodatabase and is shared and edited as a feature service.
GeoAnalytics parallel desktop processing
The GeoAnalytics Desktop tools provide a parallel processing framework for analysis on a desktop machine using Apache Spark. Through aggregation, detection, and clustering, you can visualize, understand, and interact with big data. These tools work with big datasets and allow you to gain insight into your data through patterns, trends, and anomalies. The tools are integrated and run in ArcGIS Pro in the same way as other desktop geoprocessing tools.
Profile viewing
New for 3D views is the ability to create a profile viewing state. You can interactively add a profile line in the scene, and the view automatically shifts to display a vertical slice of the content. Viewing 3D data that is vertically stacked as a profile view provides a clearer representation of your content. The profile view is a temporary viewing state and is useful when you want to see your content from a side-on viewpoint. The view adjusts to clip and focus on the content only in the profile construct area. The scene view automatically switches from the default perspective drawing mode to parallel drawing mode to preserve relative proportions of any objects.
