Field survey that works where the signal doesn’t.

One app for the whole site visit

Open a module from the side menu. Each one fills in the GPS position by itself, takes photos, and saves to the phone. Tap the ? at the top of any module to see how it works.

• Terrestrial Survey

  Ground control points and checkpoints, stake-out, flight logs with a pre-flight checklist, flight planning for the L3, L1, P1 and Phantom 4, PPK jobs, a checkpoint accuracy report (ASPRS 2023), laser-scanner station logs, and mission areas as KML or CSV.

• Environmental Survey

  Vegetation, waste, soil, air and noise observations. Pick a category from a list, add photos, and let photo recognition suggest what it shows.

• Biodiversity

  Quick sightings, point counts, transects and quadrats, with a running species list and diversity scores explained in plain English.

• Land & Scene Analysis

  Photograph the land and the phone suggests what it is and how much of the picture is trees, grass, soil, water or road.

• Compass & Azimuth

  A live compass dial with magnetic and true north, pitch and roll. Record bearings with notes and photos.

• Qibla

  The direction of the Kaaba from where you stand, with a pointer on the compass dial and “turn left / right” guidance.

• Socio-economic Survey

  Build household questionnaires like KoboToolbox: numbered questions, choices listed as round buttons or tick boxes, skip logic and consent. Answers stay on the phone, export as Kobo-style CSV, and each response shares as a PDF. Print the form on paper as a back-up.

• Way Back

  Mark where you started, drop spots along the way, and get walking directions back when you are lost, online or offline.

• Land Survey

  Survey a plot with the phone’s compass and any tape or rule: walk the boundary beacon to beacon while a line guide keeps the tape on line. Back bearings catch compass errors; Fieldra gives the closure, adjusts the corners, works out the area and makes a survey report.

• Road Survey

  Drive a road to record its line, and mark potholes, cracks and blocked drains along the way. The line keeps recording with the screen off.

• Water Survey

  Sampling points, scanned bottle labels, and readings from Bluetooth water meters that fill in the form by themselves.

• Field Tools

  GNSS averaging, LiDAR distance on iPhone Pro, tree and building height, area walk, barometric height, sound level, magnetic anomaly and a label scanner. Each tool explains itself with a drawing of the real instrument.

• Survey plans

  Draw the study area and the points to visit for each module, with unique plan names. Tap a planned point for walking directions to it.

• Photo Gallery

  Every photo in the project, organised by category. Swipe through them full screen, open the record, share, save or remove.

• Nearby Devices

  A radar shows the phones and computers with Fieldra around you, by name. Send a whole project, or just part of it, over Wi-Fi, deletions and office layers included; an interrupted transfer continues where it stopped.

• Map, Records & Export

  See everything on a map with tools in one bar like Fieldra Desktop’s: tick layers on and off (office layers too), go to a coordinate, switch to satellite, and put the map on an A4, A3 or Letter page with a legend, north arrow and scale bar as a PDF or image. Browse every record, export or sync the project, and navigate on your own orthomosaic (MBTiles from DJI Terra or Pix4D) with no signal.
