 ## Overview
 
 ThRasE is an open-source QGIS plugin designed for manual post-classification correction and quality assurance of thematic maps. It provides a comprehensive workspace for editing raster classifications through synchronized multi-view panel configurations that enable blending multiple layers for visual comparison. The plugin features a recode pixel table for modifying multiple classes simultaneously through precise editing tools for pixel-level corrections. An integrated modification tracking system records every change with timestamps and original values, enabling traceability and visual highlighting of edited areas. Systematic tile-based navigation ensures complete spatial coverage during inspection, while session persistence enables seamless multi-day workflows by preserving workspace configuration and review progress.

 ## When and Why Use ThRasE?
 
 Thematic maps are essential tools that translate complex spatial data into actionable insights, but their reliability depends on rigorous quality assurance. Automated classification methods, while powerful, inevitably introduce errors. Satellite-based classifications can produce errors of omission or commission, scale mismatches, or temporal misalignments with ground conditions. These limitations don't undermine the value of thematic maps, but they highlight the critical importance of quality assurance.
