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.

Survey data Drop a radiometric survey export here Delimited line data (CSV, TXT, XYZ) with radioelement channels and coordinates. Column names are matched case-insensitively — K, U, Th, total count, elevation, X/Y or lon/lat. Supported: GeoTIFF/COG, Geosoft and Surfer grids, ER Mapper, Esri grids, ENVI, IMG, GXF, NetCDF, HDF, SAGA, KEA, PCIDSK, Idrisi, ASEG-GDF2, delimited tables, and ZIP or nested-ZIP deliveries.

No survey data uploaded Nothing is inferred or assumed before an upload — processing options unlock only for channels actually present in your file.

Processing

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