GeoLibre is built with Tauri v2, React, TypeScript, MapLibre GL JS, DuckDB-WASM Spatial, and deck.gl. The same workspace runs as a native desktop app, a native Android app, in any modern web browser, and adapts responsively to mobile and small screens.

Features (v2.2)

• Runs across desktop (Tauri), web (browser), native Android (Tauri v2 mobile), and mobile or small screens, with a responsive, touch-friendly layout that adapts menus, dialogs, and panels (on phones the Layers/Style panels overlay the map as slide-over sheets), plus per-panel visibility through Layout settings
• MapLibre map workspace with OpenFreeMap, Protomaps, EOX Sentinel-2 cloudless, and Openbasiskaart basemaps, planetary basemaps for Mars and the Moon (OpenPlanetaryMap) plus Mercury, Venus, the Galilean moons (Io, Europa, Ganymede, Callisto), Titan, Pluto, and Charon (USGS Astrogeology, reprojected to Web Mercator by the tiles Worker) with a per-project ellipsoid whose radius drives distance, area, and scale measurements and a planet switcher in the Layers panel, stacking of multiple raster basemaps, blank background support, double-click to swap the core basemap from the layer panel, a right-click context menu for reading coordinates and quick actions, a Gridlines coordinate-grid overlay with edge labels and a UTM easting/northing grid mode, and toggleable navigation, fullscreen, geolocation, globe, terrain, scale (switchable between metric, imperial, and nautical units), attribution, and logo controls, plus a View menu with viewport history navigation, a reset pitch and bearing control, a distinct north arrow, and View in Google Maps and View in Google Earth actions, and a double-click terrain control for setting vertical exaggeration
• Multi-map grid that splits the workspace into a grid of synchronized map views, so you can compare basemaps, layers, or time steps side by side, with any pane switchable to an optional CesiumJS 3D globe (camera-synced with the 2D maps; requires a Cesium Ion token — see Environment variables)
• Load local vector layers supported by DuckDB-WASM Spatial, including common formats such as GeoJSON, GeoParquet, GeoPackage, Shapefile, FlatGeobuf, KML/KMZ (honoring embedded symbology, rendering GroundOverlay images as map overlays that animate through the Time Slider when time-tagged, and displaying embedded Collada .dae 3D models), GML, delimited text (including CSV without coordinates loaded as a standalone attribute table), GPX, and OpenStreetMap PBF extracts (parsed in-browser with osmix)
• Reproject vector layers to EPSG:4326 on load, render vector layers that carry Z coordinates in true 3D rather than flattening them onto the ground plane, and split dragged GPX files into named waypoint, track, and route layers
• Large local vector layers render through client-side vector tiling, with a warning before loading very large files
• Add Data menu for XYZ tiles, WMS and WFS (with layers and feature types discovered from the service's GetCapabilities so you pick from a populated dropdown), GeoJSON URLs, GeoRSS feeds (URL or file), vector tiles (including OGC API - Tiles vector tile services), COG and GeoTIFF rasters, Cloud-Optimized NetCDF/HDF (via kerchunk references) plus local HDF5 and NetCDF-4 files, MBTiles, ArcGIS FeatureServer and VectorTileServer layers, PMTiles, Zarr, LiDAR, 3D Tiles (including authenticated tilesets via custom request headers), ArcGIS I3S scene layers (Integrated Mesh and 3D Object layers rendered on deck.gl), CAD drawings (DXF/DWG) with a drawing-layer picker and CRS selector, Esri File Geodatabases (.gdb folders, desktop) with a feature-class picker and automatic reprojection, Gaussian splats, glTF/GLB 3D models placed at coordinates, georeferenced video overlays, and geotagged photos imported as a point layer from their EXIF GPS (with manual placement and drag for photos lacking coordinates, and a true native-resolution photo viewer), with a fully internationalized dialog, comma decimal support, drag-and-dropped CSV coordinate files, sample-data dropdowns on every upstream-backed panel for loading ready-made example datasets, and a saved service library for storing and re-adding frequently used web-service endpoints
• QGIS-style Browser panel (Data Source Manager) for exploring and adding data from one place: browse map Services and Recent items, connect to PostGIS databases and browse their schemas and tables, drill into local files, save and reopen Favorites, add a New connection per service kind, with full keyboard navigation of the tree
• Deck.gl Layer builder for composing deck.gl overlays from uploaded files or remote URLs
• Cloud data integrations through the Planetary Computer and Earth Engine panels, the Overture Maps plugin, and federal Web Services plugins
• Manual and automatic refresh for WFS, GeoJSON URL, and Add Vector Layer URL layers
• Layer panel for visibility, opacity, reordering, rename, zoom-to-layer, identify, labels, open attribute table, export, and remove actions, with collapsible layer groups/folders for organizing the layer stack and a Search places box in the footer for geocoding to a location without leaving the panel
• Live style panel with single, categorized, graduated, expression, and rule-based (filter-driven) symbology (fill, stroke, opacity, circle radius), proportional symbols, fill patterns, a built-in marker library, plus point heatmap and clustering renderers — all including for Add Vector Layer point layers, plus an inline color ramp picker that previews each colormap's gradient on the trigger and beside every option, and a transparent (no fill / no outline) option in the color picker, with vector layer symbology that imports and exports as OGC SLD, QGIS QML, and Mapbox GL style JSON so styles round-trip between GeoLibre, QGIS, and the Mapbox/MapLibre ecosystem; the rule-based renderer carries per-rule symbol properties, scale-dependent visibility, nested rules, and per-rule toggles (and can hide features matching no rule), and the style toolkit adds diagram symbology (pie, donut, and bar charts drawn on features), a symbology pack of inverted-polygon masks, arrow and marker lines, and geometry generators, data-driven proportional sizing for marker icons, and a Style Manager that saves reusable symbol, color-ramp, and label presets to a personal library and applies them across projects
• Data-defined label engine for labeling vector features by any attribute or expression, with ArcGIS-style placement and styling controls (anchor, X/Y offset, rotation, wrap width, letter case), expression-driven label properties, placement priority, a Duplicate labels option, and unique/concatenate modes that collapse points stacked at the same coordinate into a single deduplicated label
• Attribute table with filtering, sorting, resize controls, feature highlighting with Ctrl- and Shift-click multi-row selection, optional zoom to selected features, add-field and field-calculator tools (including geometry length and area calculation), virtual fields (expression-backed computed columns that update with the data), persistent attribute joins configured in layer properties, an attribute form designer with edit widgets, validation constraints, and conditional field visibility, a Charts panel (histogram, scatter, bar, line, box), a field statistics summary panel, column management (rename, delete, hide/show, reorder) with a column explorer for finding and toggling fields in wide tables, virtualized rows for large layers, and export to GeoJSON/GeoParquet/Shapefile/GeoPackage/CSV, plus a Raster Attribute Table for single-band categorical rasters
• Shared Expression Builder with a function reference, searchable field list, live preview, and reusable variables, wired into filters, labels, styling, field calculation, and selection, plus Select by Expression and Select by Location for building feature selections
• SQL Workspace for running DuckDB Spatial SQL against loaded layers, local files, and remote URLs, docked as a resizable panel beside the map with editor autocomplete for tables, columns, and SQL keywords, sample queries, query history, and adding results to the map or exporting them, plus an in-browser PostGIS SQL engine via PGlite and an Apache Sedona spatial SQL engine
• Multiple DuckDB SQL query-result layers with identify, selection, and attribute table support
• Controls menu with Measure (including terrain-aware 3D measurements), Bookmark, Minimap, View State, and Map annotation tools (draw text, arrows, and highlights on the map, saved with the project), a Search panel, persistent mode banners for the Directions and Reverse Geocode tools, a Camera Tour recorder that captures an animated keyframe tour to video (with per-keyframe recapture, per-keyframe hold and transition duration controls, and saving/loading a named tour setup as JSON), a Dashboard panel of configurable chart widgets that summarize the loaded layers, and a Print menu with a print layout composer (user-editable legend, explicit map-scale input, title block with editable title and footer, page-size controls, a custom print extent, attribute-table and chart blocks, Atlas / map series generation that produces one page per feature or a uniform series of pages along a line, and Copy to Clipboard) that exports the map to PNG or PDF
• Record the map canvas, or a drawn bounding box, to a video file straight from the browser (with an o
