Software-package Attrack

Software for onshore and offshore microgravity and seafloor subsidence/uplift; data processing, modelling and analysis. The software package Attrack can be used for gravity, microgravity, time-lapse gravity and seafloor height data. It is developed by Quad Geometrics and used in-house for providing services to customers. We also offer licensing of the package to clients.

Features

Selection for either onshore or offshore data
5 modules, for:
- Modelling
- Survey simulation
- Survey processing
- Time-lapse
- Utilities
Input formats are:
- Quad Geometrics CG-5 and CG-6 internal format (at 6 Hz or 10 Hz sampling)
- Scintrex standard CG-5 and CG-6 formats
- Octio CG-6 internal format
- External data of various formats
Data are resampled to a chosen rate, for on-the-fly processing through to station values
Station uncertainties are estimated together with station values
User manual of 300+ pages describing the theory behind each step and option. It explains the graphical user interface (GUI): algorithms, data and parameter input/output, and the Attrack data flow
Object Oriented language (Python)
- Structured for ease of modifications/extensions
- Graphical user interface (GUI) using Qt for Python (PySide2)
- Version 3.1 September 2023
- 15 man-years of programming, design and test work has been put into Attrack

Benefits of Attrack

State-of-the-art methods and algorithms

The processing is reproducible

User interface which is intuitive

All of microgravity is kept within the same software package

Easy to keep multiple versions of the data, with different parameter settings

Attrack modules and data flow

Data are shared between modules
Processing results from multiple surveys are analysed in the time-lapse module
Model and real data are compared in the time-lapse module
Survey simulated data can be run through the processing and time-lapse modules
Output to spreadsheet or text-files from modelling and time-lapse module
