◇ Substrate

Read the ground like a field geologist — from orbit.

Point at any place on Earth. Substrate pulls the latest satellite pass and reads the ground's hidden spectral signature — iron, clay, alteration, moisture, bedrock geology — the tells a trained eye looks for, rendered in two clicks.

The gap it fills

Alteration mapping used to cost thousands. Or a GIS degree.

Between free-but-clunky and enterprise-expensive, there was nothing a working explorer could just use. That's the hole Substrate sits in.

The consultant
$2k–$20k

Per report. Weeks of turnaround for the alteration study on a single claim.

The software
$2,000/yr

An ENVI or ArcGIS license — plus the training to drive it. Desktop, not the field.

Substrate
Two clicks

Same iron/clay/alteration reads, self-serve, in your browser. Free to start.

What it sees

Every band a prospector actually reads

Computed spectral indices from Sentinel-2, Landsat, ASTER and SAR — draped over live Macrostrat bedrock geology.

Iron Oxide

Rust from orbit — hematite, goethite, limonite, bog iron and laterite.

Ferrous Minerals

Unweathered iron — magnetite, ilmenite, pyrite, and buried metallic structure.

Clay · Hydroxyl

Alteration halos and clay bodies — where a mineral system leaked to the surface.

Bare Soil

Disturbed earth — excavation, cutbanks, tillage, and cleared ground under cover.

Bedrock Geology

Macrostrat units, faults and formation boundaries — live under every scan, click to identify.

+ the living surface

Vegetation, moisture, water, burn scars and heat — pixel inspector, scene compare, GeoTIFF export.

Who it's for

Built for people who read the ground for a living

Independent prospectors Junior exploration teams Remote-sensing & GIS consultants Earth-science researchers Data journalists Land & resource scouts
The tiers

See more of the invisible as you climb

Every tier reads the same free public satellite data — you pay for depth, volume, and the professional tools.
