Tissot Processing Provider QGIS 4 compatibility
Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Projection distortion analysis, cartographic linting, map quality scoring, spatial diffing, and autofix — powered by a Rust core.
About
Tissot brings visual-first geospatial diagnostics into QGIS as a Processing provider. Analyze projection distortion with X-Ray heatmaps and Tissot ellipses, lint your data for cartographic and data quality issues, generate a 0–100 map quality score, visually diff two datasets, and auto-fix problems like suboptimal projections and topology gaps. All computation runs in a high-performance Rust core via the Tissot Python API. Requires the 'tissot' package installed in the same Python environment used by QGIS.
