MapMerger™ Geospatial Vector Conflation

In a world where mountains of new, high-quality vector data overlap, how do you keep project costs down and incorporate this fresh data into your baseline data holdings? L3Harris MapMerger is the solution. This data conflation tool manages two or more overlapping vector datasets and merges them seamlessly.

L3Harris MapMerger geospatial conflation tool accurately merges vector content of the same feature type by automating common tasks. The tool resolves vector data conflicts in seconds by updating alignment conflicts and transferring metadata and attributes to the newly integrated data. MapMerger can be used as an extension of the ESRI company's ArcGIS software.

Key capabilities: 

Match strategy – Allows users to select tailored parameters for your dataset and stores the preferences to be applied to additional datasets.

Metadata – Records and recalls conflation experience of every point, line, or polygon that is processed.

Auto-tiling – Divides larger areas into tiles so more than one person can work on a part of the larger areas at the same time.

Algorithms – Applies real-world tested algorithms to precisely position the data points, lines, and polygons in the newly created, customized, fit-for-purpose datasets post conflation.

Spatial accuracy – Prevents distortion to the absolute ground position of the assets. There are no jointables to conflate using this solution.

MapMerger automates common conflation tasks:

Attribute Transfer

Sometimes referred to as a spatial join on steroids, MapMerger transfers attributes from an attribute-rich map to a map with better geometry. Learn more here.

Feature Densification

MapMerger connects and adds features that exist in one map to another map where they did not originally exist. Learn more here.


MapMerger precisely aligns features in two overlapping maps by ensuring that matching features share the same geometry. Learn more here.

Asset Realignment

MapMerger repositions network assets to align with a more accurate basemap. Learn more here.
