Build geo-electric sections right in your browser.

GeoSection turns your VES soundings into clean, presentation-ready resistivity sections — with lithology, topography and one-click export. No accounts, no uploads to a server.

Everything you need for a clean section

The same section engine used inside Resicloud — extracted as a free standalone tool.

Multi-sounding profiles

Drop in any number of VES soundings and arrange them along your profile line — equal-spaced or by real distance.

Smart lithology

Auto-suggested lithology from resistivity ranges, with a built-in library plus your own custom patterns and colors.

Topography & depth

Toggle ground-surface topography and control max depth to focus on the layers that matter for your study.

Distance-aware

Use lat/lon or along-profile distance to keep horizontal scale geologically honest.

Excel round-trip

Import your VES models from Excel and export the section dataset back — same shape, no lock-in.

PNG export

One-click export of the rendered section as a high-resolution PNG, ready for your reports and presentations.
