Spectra Radiometrics · Terrain
Airborne gamma-ray spectrometry platform

Radiometric survey data,
processed to interpretation.

Spectra takes raw gamma-ray spectrometer and terrain data from acquisition through gridding, channel processing, ratio and ternary products, interpretation and export — with every output traceable to the survey that produced it.

01 Channel processing K, eU, eTh and total count gridded from your own survey lines.
02 Ratios & ternary U/Th, U/K, Th/K and RGB composites for lithological discrimination.
03 Terrain context DEM, hillshade, slope and aspect derived alongside every survey.

Site intelligence

Geology, tenement, historical work and logistics context that informs how the radiometric data is interpreted.

Site notes Notes are attached to the project and included in exported reports.

Data upload

Upload the survey export. Spectra reads the header, detects radioelement and coordinate channels, and reports exactly what it found before anything is processed.

Processing

Select outputs and grid them from the uploaded survey. Products without their required channels stay disabled with the reason shown.
