Analyze SEG-Y files directly in your Browser.

A professional, lightweight tool for visualizing, processing, and interpreting Sub-Bottom Profiler and shallow seismic data. No installation required.

Your Data Stays on Your Device

We take your data security seriously. When you "upload" a file, it is processed entirely locally within your browser's memory using JavaScript. Your proprietary SEG-Y files are NEVER uploaded to any server or cloud.

Comprehensive Toolset

Everything you need to process, interpret, and export your shallow seismic data, neatly organized into an intuitive sidebar.

Smart File Parsing

Drag and drop your .sgy files. The app automatically detects IEEE/IBM float formats, endianness, and trace lengths. It supports automatic conversion of Decimal Degrees and Arc-Seconds directly into UTM coordinates.

Signal Processing

Clean up raw acoustic data on the fly. Apply custom Band-Pass (Ormsby) Filters to remove low-frequency swell and high-frequency noise. Use the AGC (Automatic Gain Control) window to normalize amplitudes and reveal deeper reflectors.

Image Settings & Adjustments

Customize your view instantly. Adjust Depth Ranges (in meters), apply Time-Variant Gain (TVG) to compensate for acoustic attenuation, modify Contrast/Brightness, and choose from standard palettes like Inverted Grayscale or Seismic.

Horizon Digitization

Interpret stratigraphy directly on the profile. Hold CTRL + Click to draw continuous segments. Click normally to break segments. Drag points to edit, or right-click to delete. Export multiple layers simultaneously to DXF (3D CAD) or CSV formats.

Interactive Navigation Map

Visualize your boat's track on a floating satellite map. The built-in Despiking algorithm automatically cleans GPS errors and outliers. If your file only has raw UTM meters, simply set the Fallback Zone to georeference it instantly.

Measure & Zoom

Use the Left Mouse Button to drag a bounding box and perform a precise Window Zoom. Use the Right Mouse Button to draw a ruler and measure distance, traces, and TWT/depth differences between any two points.
