Collect photos in the field

  1. Projects → Create project. Name it on the Project Name tab.
  2. On Labeling Setup, look under Collect data and open Photo Collection. Pick the template closest to your task:
    • Crop health photos: up to four photos of one plant, with the crop, the affected part, the symptoms and the severity
    • Water point survey: one to three photos of a borehole, well or tap, with its type, whether it works and how many people are waiting
    • Signs and text in local languages: one photo of a sign, with its languages, script and an exact transcription (for scene-text OCR)
    • Document pages: every page of one document in reading order, at higher resolution, with the kind of document, languages, script and whether it is printed or handwritten
  3. Still on Labeling Setup, edit the lists (your crops, your water-point types) and the <ImageRecord> settings: maxPhotos, minPhotos, location="ask" to save where each photo was taken, maxWidth and quality for file size. The preview lets you try the camera; nothing is uploaded there.
  4. On Data Import, upload one task per site, plant or document: a CSV with a prompt column, such as WP-0142, Dala ward or Farm 7, plot B. Save.
  5. Contributors open a task on their phone, tap Take photo (or Choose a photo for pictures already on the device), fill in the fields and Submit. Photos taken offline wait on the device and upload when the connection returns.
  6. Export: Export → JSON gives every photo's URL, size, time and location with the answers; the media-bundle ZIP adds the photo files.

iPhone HEIC photos, TIFF and AVIF files are converted to JPEG on upload, so contributors can pick whatever their phone saved.

Going deeper: <ImageRecord> for every attribute and the result format, <Select> for the language and script lists.
