The geoDB guide
Every topic is readable here — and most can show you, live, in the real app. Ask Petra anything; she's grounded in the same guide.
New here? Start here
The setup path, in order — from a fresh project to your first data on a map. Invited into someone else's project instead?
Getting set up
Setting up a project
Four wizard steps — name, coverage area, coordinate system, elevation — and your dashboard tracks where you are.
WalkthroughLand holdings — claims, leases and boundaries
Bring in claims and lease boundaries from GIS files and see them on every map.
WalkthroughTopography and elevation (DEM)
Request elevation for your project area once — 3D terrain and automatic elevations follow.
WalkthroughInviting your team
Invites, roles and what each person can see and touch.
WalkthroughStaking new claims — the claims door
Lay out or upload a claim block on your project map — geoDB handles staking, location notices and filing.
WalkthroughCoordinate systems — reference vs working grid
Two CRS settings, what each controls — and why your original coordinates are never touched.
WalkthroughFinding your way around
The rail, the dashboard, the project switcher, and where Petra lives — two minutes of orientation.
Getting data in
Understanding your data
How assays are stored
Sample → assay → certificate → method → lab: how lab results are stored and why.
ConceptChoosing drill-intercept boundaries
intercepts are nested — sweep scales, never a cutoff
WalkthroughQC insertion protocols — setting the rules
How often a standard, blank or duplicate goes in — and how a project runs more than one set of rules.
WalkthroughThe QC system — trusting your numbers
Standards, blanks and duplicates — and the verdict pages that judge every certificate.
WalkthroughSampling passes & composites
Two samples over one interval? Passes: Au bags + ICP composites, both real
WalkthroughSoil programmes — planning QC for a surface grid
Group a surface grid into a programme, then plan its CRM, blank and duplicate bags before the crew goes out.
QAQC
Blank thresholds
supplier limit, then your limit, then an opt-in DL floor
ConceptBlank types
coarse tests prep, pulp tests assay; order matters
ConceptCertificate SD fields
1SD/CI/tolerance/EU are not interchangeable
ConceptThe 2SD/3SD rule
multiple 2SD OR one 3SD fails; a single 2SD warns
ConceptChoosing CRMs
bracket the deposit; few CRMs with many results
ConceptDuplicates near DL
near DL, RPD is noise — use an absolute test
ConceptDuplicate measures
RPD = 2× HARD; tolerances widen up the chain
ConceptDuplicate validity
last-split, wrong batch/lab/method void a pair
ConceptExpected failure rate
~4.6% outside 2SD is normal; zero is suspicious
ConceptFailure response
diagnose field→entry→lab before any re-assay
ConceptInsertion rates
~20% total, 4–6%/type; compute the achieved rate
ConceptNo certified SD
own-lab repeats or ±10%±2DL — never batch scatter
ConceptNo code mandates numbers
every threshold is convention, not law
ConceptThe nugget effect
coarse-gold scatter is geology, not QC failure
ConceptConsecutive outliers
two same-side 2SD in a row = bias, random 2.3%
Seeing your data
The interactive map
Layers, base imagery and styling — your project on one live map.
WalkthroughThe Canvas
A workspace of live panes — figures, tables, maps and Petra, side by side.
ConceptClaim plotting
From location notices and survey paperwork to plotted claim polygons on your map — starting from a chat upload.
WalkthroughThe 3D viewer
Terrain, drill traces and downhole data in a live 3D scene — no desktop software needed.
Sharing your data
API access and vendor grants
Give a vendor a scoped key and let their software pull — you never export for them again.
WalkthroughMap layers (lines and areas)
Your geology map as live data: sketch it in the field, trace it in QGIS, publish it to the web map and every crew phone.
WalkthroughDatarooms
A curated, always-current room of project material — share a link instead of maintaining a folder.
WalkthroughExporting data
Clean CSV or Excel of anything in the project — big jobs run in the background.
WalkthroughODBC — live database access
Leapfrog, QGIS and friends read your drilling live — no export files, ever.
WalkthroughQGIS and the field app
The QGIS plugin and the mobile field app — the same project, at the desk and at the rig.
