Geo Data Collector is an advanced field data collection mapping app Flexible form designer and adhoc in-app form building Supports saving data in GeoJSON and conversion to GeoPackage Vector Features and other formats coming soon. Form design is a JSON file that’s easily shared and distributed to other users. Design form on our form builder webpage https://mapdata.xyz/form_generator/ or in the app This works completely offline (all data is stored locally in the app) Does NOT Require any server-side database or ESRI featureserver or any API like OGC WFS-T to use this. NO proprietary formats. Supports capturing of Points, Lines or polygon geometry and Point Averaging and Point Offset Rapidly switch between forms Review collected data, edit collected data, delete a record, go to location on the map Add photos from camera or from Photos/Gallery Attribute table/grid with search for both collected data and user loaded data. Advanced vector tile basemap with 11 styles to choose from (online/offline) including a Terrain/Topo style, 3D Building style (when tilted), Bright,Positron, Toner, DarkMatter and hybrid Online raster tile basemaps from ESRI Optional in-app purchase for Offline Map Data (to users area of interest) OpenStreetMap Vector Tiles with more than 8 Stylesheets to choose from including Terrain/Topo Style Contour Lines Vector Tiles Hillshade Raster Tiles Satellite Imagery Raster Tiles GADM Boundary Support for user loaded mapping data: GPKG vector features (users can style their data also supports dynamic raster tiles generation for handling big data) GeoJSON Vector GIS Data with attributes (users can style their data) MBTILES - Raster tiles MBTILES - Vector tiles (users can apply a style their data) GPKG - Raster Tiles (EPSG:3857 web mercator only) In-App Vector Data Converter - convert User Zipped Shapefile (WGS84), KML, GPX, CSV, WKT to GeoJSON Vector Layers Reference overlays that can be turned on and displayed on the map Layer Display Order - to control the display of different data Advanced Map Features: Display Latitude and Longitude (MGRS and GARS GRIDS) Display Magnetic Declination Measure Linear and Area Distance Spatial Bookmarks - Placemarks feature - save reference to a spot with notes Advanced geolocation settings with follow (move the map) and follow with heading or course Other capabilities: Go to Coordinates - move the map to Lat Long or other coordinates Coordinate Converter Geolocation Sharing Weather Conditions/Forecast Sunrise/Sunset, Time, Timezone, Elevation GPS Tracker/Recorder - record track and share as GPX or GeoJSON Open Street Map Search (nominatim place names and addresses and overpass API for points of interests) Compass Settings to turn off coordinate box File Manager Office File (Word, Excel, Powerpoint) Viewer, PDF Viewer, Image Viewer Easily Upload and Download files via: Cloud Integration (Dropbox and SugarSync) FTP Server & WEBDAV servers WIFI Sharing - share content on your phone/tablet and even allow uploading of files via a webpage accessible on any device on the same network Intuitive easy to use interface Forms support (Text field, text area, select/drop down, number, date field, check box and radio button ) You can denote fields as required or optional For select/drop down you can allow the user to support multiple selections. No Need to build Project file with desktop GIS Software like QGIS or Global Mapper (Input, QFIELD, Global Mapper Mobile) There is no vendor lockin as there is no Back-end Service or Database Required Optimized for both iPhone and iPAD works with internal GNSS Receiver (iPhone and iPAD 4G/5G) as well as External Bluetooth GNSS Receivers We can Build custom Solutions to suit your needs and requirements and workflows geodatacollector@techmaven.net ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | AppUpdate | $14.99 | per year | ## Version history (last 5 releases) ### 1.3.0 — 2026-08-15 Version 1.3 — External GNSS & RTK Support NEW: External GNSS Receiver Support Connect to Bluetooth LE GNSS receivers (Bad Elf, Trimble, EOS Arrow, Juniper Geode) Full NMEA 0183 sentence parsing (GGA, GSA, GSV, GNS, GST, RMC, ZDA) Multi-constellation support: GPS, GLONASS, Galileo, BeiDou Real-time fix quality display (Autonomous, DGPS, RTK Float, RTK Fixed) Satellite count, HDOP, PDOP, accuracy metrics Auto-detect receiver model by Bluetooth name NEW: RTK Corrections (NTRIP) Built-in NTRIP client for centimeter-accuracy positioning Sourcetable browser with mountpoint selection Automatic GGA position reports to NTRIP caster RTCM3 message parsing and relay to receiver Correction age monitoring Credential storage in iOS Keychain NEW: Quality Gate Configurable minimum fix quality threshold Maximum HDOP/PDOP filters Minimum satellite count requirement Signal quality (CN0) filtering Bluetooth RSSI monitoring Hysteresis with consecutive-epoch stability requirement Automatic reject when fix goes stale NEW: GNSS Settings Screen Switch between device GPS and external receiver Receiver connection status and satellite info NTRIP configuration (host, port, credentials, mountpoint) Quality policy configuration IMPROVED: Map position source switches seamlessly between device and external GNSS Form data capture uses high-accuracy position when available Performance and stability improvements ### 1.2.0 — 2026-07-24 Version 1.2 — TAK & Meshtastic Integration NEW: TAK Server Connectivity Connect to FreeTAKServer, TAK Server, or WinTAK via TCP Automatic position broadcasting (PLI) every 30 seconds See team members as live markers on the map Quick tactical status: Moving, In Position, All Clear, Hold Position Emergency SOS broadcast to all connected contacts Tactical alerts: Rally to Me, Under Fire, Casevac Needed, Medevac NEW: Meshtastic LoRa Radio Connect to Meshtastic radios via TCP for off-grid communication Send and receive text messages over the mesh network Share GPS position without internet or cell service Mesh node positions appear as markers on the map NEW: GeoChat Real-time messaging with team channels Messages from TAK Server and Meshtastic in one place Emergency channel for critical alerts IMPROVED: Minimum iOS version updated to iOS 17 Performance and stability improvements ### 1.1.1 — 2026-06-17 Bug fixes and UI improvements ### 1.1 — 2026-06-15 Removed in app purchases and bug fixing ### 1.0 — 2022-07-27 No release notes. ## Apps similar to Geo Data Collector | App | Rating | Price | Category | | --- | --- | --- | --- | | [Y3T Patra](https://appshunter.io/ios/app/y3t-patra/id1590740765) | — | Free | Navigation | | [iCMTGIS PRO](https://appshunter.io/ios/app/icmtgis-pro/id1005401426) | 4.9 (7) | $299.99 | Navigation | | [Stadia Altimeter](https://appshunter.io/ios/app/stadia-altimeter/id1578419686) | 5.0 (1) | Free | Navigation | | [iMotoHR HD](https://appshunter.io/ios/app/imotohr-hd/id781771456) | — | Free | Navigation | | [Survey360](https://appshunter.io/ios/app/survey360/id1533262307) | — | Free | Navigation | | [topoXpress](https://appshunter.io/ios/app/topoxpress/id1500467308) | 4.0 (3) | Free | Navigation | ## More apps by Tech Maven GeoSpatial LLC - [Earth Explorer 3D Map App](https://appshunter.io/ios/app/earth-explorer-3d-map-app/id1485111764) - [Tile Server](https://appshunter.io/ios/app/tile-server/id1488162541) - [Print Map](https://appshunter.io/ios/app/print-map/id1489608021) - [GeoNames Map Explorer](https://appshunter.io/ios/app/geonames-map-explorer/id1566866256) - [Map Discovery](https://appshunter.io/ios/app/map-discovery/id1591989087) - [Map Data Explorer](https://appshunter.io/ios/app/map-data-explorer/id1591995115) All apps by Tech Maven GeoSpatial LLC: https://appshunter.io/developer/1459067502 ## Related topics [launchpoint siteright](https://appshunter.io/ios/topics/launchpoint-siteright) · [spatial data](https://appshunter.io/ios/topics/spatial-data) · [geoexpert](https://appshunter.io/ios/topics/geoexpert) · [utm geo map y2tech](https://appshunter.io/ios/topics/utm-geo-map-y2tech) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
