I am trying to use the georeferencing plug-in in UE 5.3.2. However, when placing the GeoReferencingSystem in the level, and assigning Origin Coordinates (have tried with both projected and not) it does not match up with the Widget Coordinates Inspector.
For example, the projected coordinates Im using as a origin, is Easting: 117922 and Northing: 6864294. But playing the game, the Widget Coordinates Inspector says the origin is located at Easting: 116995,342 and Northing: 6863764,177. Looking at a map, thats about 700 meter SouthWest. Does anybody have an idea why this error occures? I have tried different locations for the origin and they all seem to be slightly offset, like described above.
My projected CRS is EPSG:3008 and Geographic EPSG:4326, which I think should be right. Its a flat planet.
Hi @oliwerlundberg
Let’s see…
The issue you’re encountering with the GeoReferencing system in Unreal Engine 5.3.2, where the origin coordinates you input (Easting: 117922, Northing: 6864294) are not corresponding with the coordinates within the Widget Coordinates Inspector (Easting: 116995.342, Northing: 6863764.177), most likely has several potential reasons:
Coordinate System Incompatibility: You’re using EPSG:3008 (projected) as the origin and EPSG:4326 (geographic) as the Widget Inspector. These are incompatibles coordinate systems, and improper conversion between them could be causing the offset
GeoReferencing System Offset: Ensure the origin set within the GeoReferencing system is correctly aligned with the projected coordinates. Also, check if Unreal is interpreting these coordinates as expected (in terms of scale and units)
Scale and Units: Unreal Engine’s default use of meters or centimeters. Your coordinate system’s scaling inconsistency with Unreal’s base unit system could lead to inconsistency.
Accuracy of GeoReferencing Plugin: Inherent limitations or inaccuracies of the GeoReferencing system when employing large scales geographically or high precision
Recommended Actions:
Accurate conversion and transfer between geographic (EPSG:4326) and projected (EPSG:3008) coordinate system.
Check if any manual offset corrections need to be made in the plugin.
Test using known coordinates to double-check the system’s accuracy.
Look for updates or bug fixes in the plugin for your build of UE
