What's included

Everything in Pro

All Pro features - unlimited projects, layers, features, full import/export, offline maps, online services, and external GNSS support.

NTRIP RTK corrections

Connect to any NTRIP caster directly from Mapit GIS to receive real-time RTK corrections. This enables centimetre-level positioning with compatible GNSS receivers - no third-party app required.

• Built-in NTRIP client with colour-coded map indicator
• Support for multiple NTRIP caster profiles
• Works with any NTRIP v1/v2 caster
• Automatic mountpoint selection
• VRS corrections via GGA sentence transmission
• RTCM stream monitor with message diagnostics
• NMEA sentence type filter chips for stream inspection
• Auto-reconnect and auto-resume on app restart
• Tap the map indicator to jump directly to NTRIP settings

Works with Bluetooth, Bluetooth Low Energy (BLE), USB serial, and TCP external GNSS receivers.

See the Mapit NTRIP Client documentation for full setup instructions, compatible receivers, and configuration details.

Vertex snapping

Snap new and dragged vertices to existing features for topologically clean shared vertices and watertight boundaries. This removes hairline gaps between adjacent polygons and eliminates duplicate near-identical coordinates where lines meet.

• Vertex snap - pull new vertices onto nearby existing vertices
• Edge snap - fall back to the nearest point on a neighbouring segment when no vertex is in range
• All vertex input modes supported - tap on the map, crosshair (GPS unlocked), and during vertex drag
• Drag loupe - circular magnifier with a pulsing reach ring, showing nearby edges and vertices while dragging
• Ring closure self-snap - snap the final polygon vertex onto the first for an exact ring close
• Z inheritance - snapped vertices inherit the Z value of the target when the active layer is Z-capable
• Configurable - adjust snap radius, restrict to the active layer, and toggle edge snap independently

See Vertex Snapping for the full workflow and Snapping Settings for the configuration reference.

Advanced Editing tools

A power-user editing toolkit for polygon, polyline, and point features. Hidden behind a single master toggle so the regular edit toolbar stays clean for everyone else - flip it on once and a Tools chip appears whenever you open an existing feature for editing.

• Split - cut a polygon or polyline into two by drawing a single cut line across it. JTS-powered geometry; you choose which piece keeps the original ID and attributes, the other becomes a new feature. Optional Z interpolation along the cut for 3D layers.
• Buffer - generate a polygon buffer at a chosen radius around any feature (point, polyline, polygon). Configurable shape (filled or ring), corner style (round / mitre / bevel), line end caps (round / flat / square), and an optional negative-radius mode for shrinking polygons inwards (stand-off zones).
• Merge - combine two adjacent features on the same layer into one. JTS-powered union with on-map A / B labels and a tap-to-swap card so you choose which row keeps its ID and attributes; the other row is deleted in the same atomic step. The opposite operation to Split.
• Single master toggle - the Tools chip and the point-editing Advanced editing tools dialog section only appear when Advanced Editing is enabled. Turning the master off restores a byte-identical toolbar to the Free / Pro experience.
• Per-tool defaults - each tool remembers its preferred shape, corner style, attribute-handling, and Z behaviour between sessions.
• Map preview before commit - both tools show a colour-coded preview of the resulting geometry so you can confirm or tweak before writing to the GeoPackage.

See the Advanced Editing category for the per-tool workflow guides, and Advanced Editing Settings for the full configuration reference.

High-accuracy CRS grids

Download and enable NTv2 datum transformation grids for centimetre-level coordinate accuracy. Replaces the default TOWGS84 parameters with dense, bilinear-interpolated grids of surveyed control points.

• 15 countries supported - UK, France, Germany, Spain, Netherlands, Belgium, Switzerland, Italy, Portugal, Iceland, Latvia, Australia, New Zealand, USA, Canada
• 59 EPSG codes covered across all supported countries
• JTSK projected-space grid corrections for Czech Republic and Slovakia
• PT08 Portugal geoid model for Portuguese coordinate reference systems
• Download grids directly from Settings > Units & Coordinates
• Applied automatically to all coordinate display, import, export, editing, and search operations
• Grids are disabled automatically if your subscription expires

See Units & Coordinates - CRS Grids for the full list of supported projections.

Vertex snapping

Snap new and dragged vertices to existing features for topologically clean shared vertices and watertight boundaries. This removes hairline gaps between adjacent polygons and eliminates duplicate near-identical coordinates where lines meet.

• Vertex snap — pull new vertices onto nearby existing vertices; a pulsing orange dot marks the snap target on the map
• Edge snap (opt-in, default off) — fall back to the nearest point on a neighbouring segment when no vertex is in range
• Tap on the map and vertex drag both support snapping
• Drag loupe — circular magnifier with a pulsing reach ring and a bold orange snap target marker, floating above your finger during drags (toggleable in Settings)
• Ring closure self-snap — snap the final polygon vertex onto the first for an exact ring close
• Configurable — adjust snap radius (20–120 px), restrict to the active layer, and toggle edge snap and the drag magnifier independently

Go to Settings → Editing → Snapping to configure. Free and Pro users can see the Snapping settings row, but enabling the master toggle opens the Pro+ paywall.

See Vertex Snapping for the full workflow and Snapping Settings for the configuration reference.

Advanced Editing tools

A power-user editing toolkit for polygon and polyline features, hidden behind a single master toggle so the regular edit toolbar stays clean for everyone else. Flip it on once and a Tools chip appears whenever you open an existing feature for editing.

• Split — cut a polygon or polyline into two by drawing a single cut line across it. GEOS-powered geometry; you choose which piece keeps the original ID and attributes, the other becomes a new feature.
• Buffer — generate a polygon buffer at a chosen radius around any feature (point, polyline, polygon). Configurable shape (filled or ring), corner style (round / mitre / bevel), line end caps, an optional negative-radius mode for shrinking polygons inwards, and a configurable maximum radius up to 10 km.
• Merge — combine two adjacent features on the same layer into one. GEOS-powered union with on-map A / B labels and a tap-to-swap card so you choose which row keeps its ID and attributes; the other row is deleted in the same atomic step. The opposite operation to Split.
• Single master toggle — the Tools chip only appears when Advanced Editing is enabled. Turning the master off restores a standard toolbar.
• Per-tool defaults — each tool remembers its preferred attribute-handling and geometry behaviour between sessions via Settings > Advanced Editing.
• Map preview before commit — every tool shows a colour-coded preview of the resulting geometry so you can confirm or adjust before writing to the GeoPackage.

See the Advanced Editing category for the per-tool workflow guides, and Advanced Editing Settings for the full configuration reference.

High-accuracy transformation grids

Download and enable NTv2 datum transformation grids and S-JTSK projected-space grids for centimetre-level coordinate accuracy. Replaces the default TOWGS84 Helmert transformation with a dense, bilinear-interpolated grid of surveyed control points.

• 49 NTv2 grid entries covering UK (OSTN15), France, Germany, Spain, Netherlands (RDNAPTRANS2018), Belgium, Switzerland, Italy, Portugal, Iceland, Latvia, Australia, New Zealand, USA, and Canada
• S-JTSK grids for Czech Republic and Slovakia (mutually exclusive — activate one at a time)
• Download grids directly from Settings → MAP & DATA → Units & Coordinates
• Applied automatically to all coordinate display, import, export, manual entry, and search operations
• Grids are disabled automatically if your subscription lapses

See Units & Coordinates — Transformation grid for the full list of supported projections and download instructions.

PostgreSQL / PostGIS export

Export feature layers directly from the field to a PostgreSQL database with the PostGIS extension. The connection is made directly from the device — no relay or cloud intermediary is required.

• Two export modes — Overwrite (drops and recreates the table with a GIST spatial index) or Append (inserts into an existing table, creating it if needed)
• Confirmation step — a sheet shows the layer name, host, and database before any destructive action
• Client-side reprojection — geometries are reprojected on the device when the layer CRS differs from the configured output SRID
• Batch transactions — features are committed in batches of 250 rows; a failure rolls back only the in-flight batch, preserving earlier committed data
• Hide-toggles — each mode can be hidden independently in Settings so teams can restrict to Append-only or Overwrite-only workflows
• SSL support — disable, prefer, or require mode; credentials stored in the iOS Keychain

Configure the connection under Settings → Remote Connections → PostgreSQL.

See Exporting to PostgreSQL for the full setup and workflow guide, and Remote Connections for the settings reference.

ArcGIS Online integration

Connect your ArcGIS Online account directly from Mapit GIS to publish and manage your field data in the Esri ecosystem.

• OAuth sign-in — connect your ArcGIS Online account from Settings → Remote Connections → ArcGIS Online using a secure sign-in sheet; Mapit GIS never stores your password
• Upload as file item — export a layer as a GeoJSON file item to your ArcGIS Online content library
• Publish as Feature Service — publish a layer as a hosted Feature Service, batched in groups of 1,000 features with automatic index rebuild on completion
• Overwrite or Append — when a Feature Service with the same name already exists, choose to overwrite all features, append to the existing service, or cancel
• Upload a project — export a full project .gpkg file as a GeoPackage item in your ArcGIS Online content library
• View Mapit Content — browse every item tagged Created in Mapit GIS in your account, sorted newest first; tap any row to open the item in Safari

Go to Settings → Remote Connections → ArcGIS Online to connect your account, then use the layer or project export sheet to publish directly from the field.

See ArcGIS Online Settings for the connection setup and Export Layers for the publish workflow.

Orthometric Height (MSL altitude correction)

Convert ellipsoidal GPS altitude to orthometric altitude (mean sea level) using a downloadable geoid grid — a standard requirement for surveying workflows where elevations must match national benchmarks and topographic maps.

• EGM96 embedded — baked into the app; no download required; active by default when the feature is first switched on
• EGM2008 (2.5′ worldwide) — higher-accuracy global alternative
• 11 regional grids — national high-accuracy models for UK (OSGM15), USA (GEOID12B), Canada (HT 2.0), France (RAF18, RAF09), Poland (PLGEO11, PL-EVRF2007-NH), Switzerland (CHGEO04), Portugal (PT08), and Slovenia (GeoID-SLO)
• Grids are downloaded on demand and stored locally — works offline after download
• Active model shown as a trailing label on the Geoid model row in Survey Settings
• Altitude stored in the GeoPackage for all new captures; displayed in the map header with a ▲ prefix

NMEA receivers only

Orthometric Height applies only when data arrives from an external GNSS receiver (Bluetooth MFi, BLE, or TCP/IP NMEA). The iPhone's built-in GPS already reports MSL altitude via CoreLocation — the toggle has no effect on the internal GPS.

Go to Settings → Survey → Survey, enable Orthometric Height, then tap Geoid model to open the picker.

See Survey Settings — Orthometric Height and the Geoid Models reference for full details.
