ESRI Enhancement: Visually Displace Features Without Moving Coordinates
Esri’s cartographic tools allow you to change the drawing position of features for visualization while keeping their real geometry unchanged in the geodatabase.
This is extremely useful when you have many points with identical or nearly identical coordinates, such as:
multiple sensors at a buoy or airport
multiple events at the same reporting site
multiple records with identical lat/lon
Instead of stacking on top of each other, Esri lets you fan them out visually around the centroid.
Esri accomplishes this using:
1. Offset symbology
This is available for Point symbology in ArcGIS Pro:
Offset X, Offset Y
Leader lines (optional)
Distribute along angles
You can set the offset dynamically using an attribute or Arcade expression.
2. Symbol layer rotation & anchor adjustment
Used to rotate each symbol around the anchor point while preserving coordinates.
3. Representations / Marker Placement (Maplex labeling engine)
Advanced cartographic placement can disperse markers around a centroid.
If you want to visually separate multiple coincident points so they appear around a circle, you can compute an offset for each record using an index field.
Example:
Attribute setup
Add the fields:
Field Purpose
| pt_index | 1,2,3,... for each point sharing the same coordinate |
| pt_count | how many points share the location |
| radius | display distance (meters, feet, or symbol points) |
