Comparing differences between basemaps or datasets in QGIS is difficult when only one map can be viewed at a time. QMapCompare solves this by bringing interactive map comparison into QGIS.
The plugin supports multiple visualization methods to quickly reveal changes across styles and datasets.
While many web tools make it easy to compare map styles, QGIS has long lacked a stable, user-friendly comparison feature. This presentation introduces QMapCompare, a plugin that brings fast visual comparison directly into QGIS, letting you evaluate layers or styles in a single canvas without constantly toggling visibility. It offers the following comparison modes:
- Mirror
- Split
- Lens
This presentation also showcases practical use cases:
- Comparing basemap styles
- Comparing datasets
- Exploring historical maps
- Before/after disaster analysis
