Multi-panel synchronized map visualization workspace for QGIS 4. Open 2, 3, 4, 6, or 8 map views in a coordinated grid layout with real-time navigation syncing and laser pointer crosshair tracking.
Urban planners, environmental scientists, and demographers often need to compare multiple spatial patterns side-by-side: historical urban growth, demographic variations (e.g., age groups, income levels), hazard risks (flood zones vs. landslide vulnerabilities), or temporal policy variations.
Instead of toggling layers on and off in a single QGIS map canvas, 02-Multimap provides a unified workspace container hosting up to 8 independent map views. Panning or zooming on one view immediately coordinates all others, while a coordinated laser crosshair tracks cursor positions dynamically across all panels.
- Dynamic Layout Grids — Instantly switch between multiple panel configurations: 2 panels (1x2 or 2x1), 3 panels (1x3), 4 panels (2x2), 6 panels (2x3), or 8 panels (2x4).
- Bi-directional Navigation Sync — Drag or scroll zoom in any panel to update the rest. Optionally link navigation back to the main QGIS map canvas.
- Laser Crosshair Tracking — Move your mouse on any panel to project neon-colored crosshairs tracking the exact same geographic coordinate across all other views and the main QGIS canvas.
- Dynamic Render Modes — Configure each panel to render different source layers:
- Sync Main Map: Follows active layers in the main QGIS Legend Layer Tree.
- Focus Layer: Isolates a specific layer on top of a globally-defined base map layer.
- Map Theme: Follows a custom QGIS Map Theme (layer visibility and style preset).
- Elite Dark QSS Interface — Features a premium dark-themed styling with coordinate tracking readouts, active panel border highlights, and responsive controls.
- QGIS 4 & PyQt6 Optimized — Engineered from the ground up for QGIS 4 using PyQt6, with zero legacy dependencies and 100% English interface text.
- 100% E2E Verified — Tested using a headless automated execution harness to verify GUI rendering, grid rebuilding, and coordinate calculations under real QGIS 4.

Requires QGIS 4.0 or newer.
- Define a few Map Themes in your QGIS project (e.g., theme "1990", theme "2010", theme "2030").
- Open the workspace from the toolbar or the 02-Multimap menu.
- Choose the 4 Panels (2x2) grid size.
- Set Panel 1 to Map Theme "1990", Panel 2 to Map Theme "2010", and Panel 3 to Map Theme "2030".
- Pan and zoom around to compare urban expansion over time with real-time cursor coordinate tracking.
