Many Eyes - Citizen Science Platform with Expert Verification and Research-Ready Data

Citizen Science Platform for a Cape Town Naturalists' Society

Designed and built a clickable staff console for a Cape Town natural history society and its university partner: every project's numbers on one dashboard, a verification queue sorted by age, and a workspace where experts agree, correct or reject each observation against the project's consensus rule, with sensitive species locations kept generalised.

Impact

5 Screens
Clickable end to end

Dashboard, projects, project overview, verification queue and verification workspace. Each of the 9 projects and all 23 demo observations, species records and kit readings alike, opens its own page.

2 + 1 Expert
Consensus rule on every record

The workspace shows what the rule needs and what it has now: 2 agreeing identifiers, not counting the observer, including 1 expert, 67% agreement, to species. Machine suggestions are labelled and never count.

14 / 30 Days
Queue age alerts

Observations turn amber after 14 days in the queue and red after 30, on the queue cards and in the dashboard's backlog per taxon group, so the oldest records get a verifier first.

9 Projects
Realistic demo data

5 project types from butterfly counts to river water kits, 23 observations, 18 taxa, 12 volunteers (3 under 18), 9 staff users, 5 upcoming events and 7 needs-attention items.

The Problem

Silvertree and Kloofnek University coordinate about 25,000 volunteers, but each project ran on a different tool: a form app, paper tally sheets typed up months later, a WhatsApp group and an emailed spreadsheet. Experts verified by scrolling photo folders with no record of who agreed, threatened nest sites sat in a shared spreadsheet, school groups joined with no record of parental consent, and about a third of records were never verified.

Our Solution

Many Eyes follows an observation from a volunteer's phone through expert and community verification to research-grade data. Staff see every project and what needs a person today on one dashboard, verifiers work a queue for their own taxa, and each record is decided against the project's own consensus rule, with exact locations of sensitive species kept behind a permission.

The Challenge: Volunteer Data Researchers Can Trust

Citizen science only works if thousands of volunteers can contribute easily and the result is still good enough for research, safe for threatened species and lawful for the children and adults whose personal information it holds.

Verification Without a Record

Experts checked identifications in photo folders, with no record of who agreed with whom and no rule for when a record counts. Without a consensus rule per project, researchers could not tell a confident record from a guess.

Locations That Can Do Harm

Exact points for threatened or heavily collected species, such as some orchids and breeding raptors, can put them at risk. SANBI publishes guidance and a sensitive species list, and NEM:BA regulates threatened and protected species, so public and exported points have to be generalised.

Children and Personal Information

Under POPIA a child is anyone under 18, and processing their information generally needs a competent person's prior consent. Adults who lead school groups or youth events should be checked against the Child Protection Register and the National Register for Sex Offenders first.

Many Protocols, One Dataset

A 15-minute butterfly count on a 1 km route, a tree health survey, sky brightness in mag/arcsec² and river pH from a loaned kit each need their own fields and range checks. Inconsistent protocols, dates and locations had made most of the data unusable for the university.

Our Approach: From Field Protocols to a Clickable Console

01

Spec and Rules Research

Mapped 12 roles from volunteers, teachers and guardians to verifiers, data stewards and partner researchers, 43 screens across the volunteer app, teacher, verifier, staff and public pages, and the data model for projects, forms, training, observations, identifications, verification rules, sensitivity rules, consents and exports. Wrote down the rules the design follows: POPIA, children's consent, safeguarding checks, university research ethics, SANBI guidance, NEM:BA and GBIF publishing.

02

Clickable Demo on a Production UI Kit

Built the staff and verifier console's 5 key screens on a production dashboard kit: the dashboard with KPIs, weekly observations by verification state, backlog per taxon group, needs attention and upcoming events; projects as cards or a table; the project overview with training pass rates and top verifiers; the verification queue with bulk agree; and the workspace for species records and kit readings. Agree, correct, reject and request more information all run on local state.

03

What a Production Build Adds

The mobile-first volunteer app with offline capture and on-device face blurring, teacher and guardian consent screens, and public results pages. Integration with Pl@ntNet and a self-hosted image model for species suggestions, the GBIF Backbone Taxonomy, GBIF IPT publishing through the South African node, photo storage in Cape Town, push, email and SMS. Staff auth by role and an append-only audit log.

Why It Works: Every Record Earns Its Status

The Rule Is on the Screen

Each workspace states what the project's rule needs and what the record has, such as "Needs 2 agreeing identifiers including 1 expert: has 0 agreeing, 0 expert", next to every human identification with who made it and when.

Machine Suggestions Stay Suggestions

Image recognition results are shown with their scores and look-alikes, clearly labelled as not an identification. They help a verifier start, but they never count toward consensus.

Exact Points Behind a Permission

Each record shows its public location and why it was generalised: a sensitive taxon, a young observer or the volunteer's own choice. The exact point stays locked behind Show exact point for staff with sensitive-data permission, and the view is recorded in the audit log.

Readings Checked Against Their Kit

Water and sky readings are compared with the expected range for the site, so a pH of 4.1 is flagged as out of range with the note that kit K-WQ-031 is overdue for calibration, before anyone accepts it.
