WBS 1 · MIDS intake

QR canvasses, calculated in the field.

Paper USGS canvasses for cement, copper, sand, and gravel — plus the GEO-5 twelve-line sheet — now open from a poster on the pit gate. Scan, fill, ingest. No accounts. No personal names.

Print QR poster

Each canvass gets a site-locked poster. Scalehouse, kiln control room, mill office.

Scan

Phone camera opens the matching form with the site already bound. No login, no names.

Capture + calculate

Commodity fields only. Clinker factor, payable copper, dry tonnes compute as you type.

Ingest

Snapshot writes to the public MIDS table. Command desk and census pick it up.

Open form

Print a site poster

Pick a canvass. The QR encodes that form and a sample atlas site. Field kit can bind any mine or census operator the same way.

Requirement verification

Critical Minerals Team backlog — MIDS Intake & QR Code Technology for Survey Process. All seven lines are live in this desk.

WBS	Task	Status	Notes
1	Setup QR Code Technology for Survey Process — improve intake accuracy and reliability	Met	Paper canvass → QR deep-link → calculated fields → public MIDS table.
1.1	Research and select QR code generation platform / library	Met	Selected qrcode (MIT, client-side). AWS Lambda QR and End User Messaging rejected — offline field kit.
1.2	Design QR workflow: Copper, Cement, Sand and Gravel — GEO-5 twelve-commodity form	Met	Scan poster → /mids/{form}?site=CODE → capture → ingest.
1.2.1	Cement — UI & calculated fields. Review forms for intake.	Met	USGS 9-4002-A: clinker factor, kiln/mill utilization, apparent consumption.
1.2.2	Copper — UI & calculated fields. Review forms for intake.	Met	USGS 9-4052-A: contained / recoverable / payable Cu, concentration ratio, SX-EW split.
1.2.3	Sand — UI & calculated fields. Review forms for intake.	Met	Twelve end-use lines, dry tonnes, concrete/asphalt/road split.
1.2.4	Gravel — UI & calculated fields. Review forms for intake.	Met	Twelve end-use lines aligned to the GEO-5 canvass.

1.1 Library decision

Field tablets at a scalehouse often have no AWS session. qrcode generates posters in-browser, prints without a network hop, and encodes a deep link into the matching canvass. AWS API Gateway + Lambda QR, End User Messaging, and Google Chart QR all require a round-trip and fail offline.

qrcode npm
MIT. Offline. PNG download + print. Already in the field-kit stack.
Selected
AWS API Gateway + Lambda QR
Needs IAM, a billed endpoint, and a network. Adds latency at the pit gate.
Rejected
AWS End User Messaging
SMS/QR campaigns, not mineral canvasses. Personal contact data we refuse to collect.
Rejected
Google Chart QR
Deprecated, network-bound, third-party image host.
