FilterMate

🧭 Explore, 🔍 filter and 📦 export vector 🗺️, raster 🏔️ and LiDAR point cloud ☁️ layers in QGIS, from one panel.

Pick a layer, select what matters on it, and FilterMate filters every other layer of the project by its relation to that selection: buildings near main roads, parcels on steep slopes, LiDAR points beneath rooftops, a DTM clipped around a church. The filters stay on the existing project layers, keep their styles, can be undone, saved as favorites, exported, and replayed from Processing or a script. Or ask for them in a sentence: the AGENT section filters, selects and exports from a request, with the model you choose.

⚙️ How it works

The panel has five sections in two stacks, one section open at a time in each: 🤖 AGENT and 🧭 EXPLORING above the splitter handle, 🔍 FILTERING, 📦 EXPORTING and 🔧 CONFIGURATION below.

Section	What you do there
🤖 AGENT (experimental)	Ask in a sentence: "buildings above 1200 m in the selected commune". The agent reads the project, filters, selects, zooms, styles and labels layers, edits features (in the edit buffer: you save them), makes print layouts, sets the CRS of the project, adds open data, runs Processing algorithms of QGIS, draws objects with SAM and exports; each step can be undone. See docs/AGENT_MODE.md.
🧭 EXPLORING	Select on the current layer. Vector: one feature, several, or an expression. Raster: a band, a pixel value (picked on the map), a value range on a live histogram, classes of a paletted raster, a raster calculator expression. Point cloud: ASPRS / LiDAR HD classes, Z, intensity and return ranges, chained attribute conditions, height above a DTM.
🔍 FILTERING	Choose the layers to filter and how they relate to the selection: geometric predicates (intersects, within, disjoint…), a buffer, AND / OR with existing filters, a minimum coverage for polygons.
📦 EXPORTING	Write the filtered layers as they are: vector formats, GeoTIFF / COG for rasters, LAZ / LAS / COPC / GPKG / CSV for point clouds, or a GeoPackage with an embedded QGIS project.
🔧 CONFIGURATION	Backends, theme, layer kinds, cache and other options, from the panel.

Nine combinations. One panel. Every kind of layer can be the source or a target. Each cell links to a detailed use case:

Source ↓ / Target →	🗺️ Vector	🏔️ Raster	☁️ Point cloud
🗺️ Vector (features)	Buildings near main roads	DTM around the church	Point cloud around the church
🏔️ Raster (value range, classes…)	Parcels on steep slopes	NDVI mask on an RGB orthophoto	LiDAR points beneath rooftops
☁️ Point cloud (classes, ranges…)	Building heights measured by LiDAR	DTM beneath ground points	High vegetation near power lines

Filtered layers keep their id, style and place in the layer tree. Unfilter, Undo / Redo and unloading the plugin put the original source back, and project files are always saved with the original sources.
