Many tools. One app.
From the first measurement to drafting, from coordinate transformation to reporting, every step of a field project, brought together in one mobile GIS app.
Draw
Points, lines and polygons with 5 m auto-snap. Tap-to-drop vertices, undo, redo and precise manual entry.
Layers & projects
Unlimited layers per project, per-layer color, visibility and style. Switch between projects in one tap.
Save current position
One-tap capture of your live GPS location as a point, with elevation, accuracy and timestamp baked in.
GPS track recording
Record your walking or driving route in real time. Pause, resume, edit and export the polyline with full timestamps.
Measure
Area, perimeter, distance, bearing and 3-point angle. Metric or imperial, live readout while you draw.
Slope
Slope along any segment in percent, permille or degrees. Two-point and along-line modes for grading work.
Elevation profile
Elevation profile and cross-section graphs along any line, sourced from SRTM DEM. Min, max, ascent and descent in one chart.
Contour lines
Generate equal-elevation contour lines automatically from SRTM DEM data. Choose the interval and overlay on any basemap.
Cut & fill volume
Compute earthwork volumes under any polygon, cut, fill and net, against a reference plane or interpolated terrain.
Coordinate systems
35+ CRS including WGS84, UTM, ED50, TUREF, ETRS89 and ITRF. DD, DMS and XY formats. Downloadable country packs.
Stake-out
Navigate to coordinates with real-time direction and distance. AR stake-out uses the device camera for precise placement.
Buffer zones
Generate buffer / setback areas around any point, line or polygon at the distance you choose.
Photos & notes
Attach geotagged, time-stamped photos to any feature, included in exports and reports.
Live field data
Live weather, auto-detected address, sun position and altitude for every measurement.
Offline & basemaps
8 map types, Apple Standard / Satellite / Hybrid, OSM, Topographic, Carto Light & Dark, ESRI Wayback. Full offline cache.
Import & export
KML, KMZ, DXF and NCZ (Netcad), GeoJSON, Shapefile, GeoPackage, CSV and TXT — round-trip with any CAD or GIS workflow.
Professional reports
PDF, Excel and TXT reports in seconds. 16+ fields, map overlays, reusable templates.
Cloud backup
Sign in with Apple or Google to sync projects across devices. End-to-end encrypted. Guest mode available.
Parcel query (Türkiye)
Query cadastral parcels by province, district, block and lot — or long-press on the map. Boundaries arrive as polygons you can measure and export.
External GNSS & RTK
Pair an external GNSS receiver over Bluetooth (NMEA), stream NTRIP corrections and watch live fix quality — from single all the way to RTK fixed.
Drone flight mode
Flight-day weather, GNSS satellite visibility, magnetic declination and no-fly zone checks — plan a safe survey flight from one sheet.
Field forms & symbology
Build custom attribute forms, fill them per feature in the field, and style layers with categorized or graduated symbology.
WMS & data layers
Add OGC/WMS services, view power and telecom infrastructure (OpenInfraMap) and geology overlays on top of your own survey data.
AI assistant · 46 languages
A built-in assistant answers app and surveying questions. The whole app speaks 46 languages, with an interactive guided tour.
Spatial analysis
Union, intersect, difference, dissolve and convex hull — plus split a polygon into N equal parts. All computed on-device.
Web share link
Turn any measurement or project into a shareable web link. Send coordinates, area and boundaries to anyone — no app required to view.
Georeferenced image overlay
Place an orthophoto, site plan or scanned map over the basemap, align it to real coordinates, then draw and measure on top of it.
3D globe
See your projects on an interactive 3D globe — a fast way to grasp location, scale and distribution at world scale.
Field-ready, every screen.
Designed for one-thumb use under sunlight, with gloves, on slow networks.
Built for the people who work with land.
If you measure it, plant it, build on it or own it, Survey is for you.
Everything below comes with the app.
MapLab Survey is free. No tiers, no paywalls, no feature locks. Every coordinate system, every export format and every report template is available from the moment you install.
