Everything you need to make a map

Grouped by what you're trying to get done.

Bring your data — and take it with you

Drag almost any spatial file onto the map. Nothing is locked in — export it back out whenever you like.

Dropped GeoJSON layers of buildings, places and a walking route on the map
  • Shapefile (.shp/.zip), File Geodatabase (.gdb.zip), GeoPackage, KML & KMZ, GPX, GeoJSON, TopoJSON
  • CSV with lat/lng or WKT geometry · FlatGeobuf · GeoParquet
  • Geotagged photos (JPEG / HEIC) — each becomes a point where it was taken, photo attached
  • GeoTIFF / Cloud-Optimized GeoTIFF (COG) rasters
  • GeoPDF map sheets — USGS US Topo quads and QGIS / ArcGIS Pro exports, placed automatically
  • PMTiles & MBTiles vector & raster archives
  • 3D Tiles archives (.3tz) and Esri scene layer packages (.slpk)
  • Export layers back out to GeoJSON, CSV and more

Open data, ready to drop in

No data yet? Pull public layers straight onto the map, then mix them with your own files.

Overture buildings saved from open data, with cafés loading on top
  • Overture Maps open data for anywhere on Earth: buildings, roads, places, addresses, land use, water and boundaries
  • Save the Overture features in view as an editable layer, with every attribute
  • Recent Sentinel-2 satellite scenes, with NDVI and other indices or false colour
  • Public map servers: GeoServer, MapServer, QGIS Server and ArcGIS (WMS, WMTS, WFS, OGC API)
  • Any URL: GeoJSON, CSV, published Google Sheets, COG, PMTiles, XYZ tiles and basemap styles
  • Web layers sync by link, so they take almost no cloud storage

See it in 3D

Elevation, extruded buildings and streamed 3D models — all in the browser, no plugins.

Sydney buildings extruded in 3D and coloured by floor count on a dark basemap
  • 3D terrain with adjustable exaggeration, hillshade (shaded relief) and a globe view
  • Extrude any polygon layer into 3D buildings — height from an attribute or a fixed value
  • Drop in city models, photogrammetry and point clouds (.3tz / .slpk), or stream a 3D Tiles URL
  • Line models up with the basemap: drop to the ground and nudge east, north or up
  • Measure true 3D distance and height on a model
  • GPU heatmaps, plus hexbin and grid counts that rise into 3D bars

Edit attributes & geometry

A full attribute table, data-entry forms and drawing tools, right in the browser.

Reshaping a building polygon with the geometry edit tools
  • Attribute table: view, sort, search and edit properties inline
  • Field calculator — derive or update columns with SQL across the whole layer
  • Add, rename, retype and delete fields, with labels, pick lists, number limits and defaults
  • Forms with required and read-only fields, help text and questions that show only when needed
  • Record who created and edited each feature, and when, plus GPS accuracy
  • Draw, move & reshape points, lines, polygons, vertex editing and snapping

Work in the field, even offline

Built for phones and patchy signal: your maps live on the device first.

A weed survey along a bush track, recorded with no connection
  • One "Make offline ready" check gets a map, its layers, photos and basemap ready for no signal
  • Save basemap areas for offline at overview, street or full detail
  • Keep editing with no connection; changes wait and sync when you’re back online
  • Touch-friendly drawing with a crosshair and GPS placement

Query & analyse with SQL

Real analysis powered by DuckDB-WASM — no database to stand up.

The SQL console with a grouped query and its results
  • Full SQL over your attributes — no setup, no server
  • Spatial ops: buffer, centroids, convex hull, simplify, dissolve (ST_* functions)
  • Results drop back onto the map as new layers you can style and export
  • Runs entirely client-side — your data never leaves the browser

Style & organise

Make it legible and keep it tidy.

Buildings styled by category with a colour scheme
  • Single, category and graduated symbology — colour schemes, custom ramps and point markers
  • Your own SVG or PNG point icons, per layer or per category
  • Live filters: range sliders and value lists that filter the map, table and charts as you drag
  • Labels, opacity, zoom ranges and saved styles you can reuse on any layer
  • Style views — the same data drawn a second way, without copying it
  • Lock a layer’s editing or style so collaborators can’t change it
  • Layer groups, folders for maps and layers, and a Layer Catalog to reuse layers across maps
  • Fast rendering with MapLibre GL + DuckDB-WASM

Charts, dashboards & rich popups

Turn attributes into answers — on the map, beside it and in every popup.

A bar chart of buildings by use docked beside the map
  • Chart Studio: bar, line, area, donut, histogram, scatter and headline-number charts, built step by step or in SQL
  • Charts follow the map — all features, just what’s in view, or your selection
  • "x of y" figures, e.g. how many of all buildings are in view, and colours that match the map
  • Pin charts to a dashboard docked beside or below the map, in the editor and shared maps
  • Popup builder: field groups, photo galleries, images, text, links, charts and video/3D embeds
  • Show popup sections only when a condition matches, e.g. status = 'Damaged'

Basemaps — and your desktop GIS

Pick the backdrop, and round-trip your work to QGIS.

The Basemap panel with a satellite hybrid basemap under the layers
  • Browse public basemaps and overlays — satellite, topo, street and more
  • Search ArcGIS Online & the Living Atlas, and add Feature Layers
  • Use any XYZ, WMTS or MapLibre style as a basemap
  • DropMaps QGIS plugin: import/export .dmap files and sync cloud layers both ways
  • A free desktop Converter turns GeoTIFF & MBTiles into stream-ready COG / PMTiles, and point clouds into 3D Tiles

Save, share & sync

Every account gets cloud storage — 100 MB free, 5 GB on Pro.

A shared map open in the read-only viewer
  • Cloud backup & sync across devices
  • Name your maps, set a Home view and capture a thumbnail for your maps list and share links
  • Share a map to anyone with a link — no account needed to view
  • Branded, read-only viewer with splash, expiry & view stats
  • Password-protected (restricted) share links Pro
  • 5 GB storage, plus stackable +10 GB packs Pro
  • Share with specific people & real-time collaboration Team

Attach photos & documents

Tie real-world media to features and browse it without leaving the map.

A feature popup with attached photos
  • Attach photos to any feature, with a built-in gallery and lightbox
  • Attach documents — PDF, Word, Excel, text and more — per feature
  • Reads media references from KMZ / Avenza PDF-Maps, ArcGIS and Earth exports
  • Stored locally by default, and backed up to your cloud storage once sync is on
