Ge0MLib (β) -- Marine geophysical data processing toolbox for engineering survey // MatLab 2015b home



Ge0MLib library includes algorithms for Marine Engineering Geophysical Survey data logging and processing. The follow tasks are concerned: Navigation, Sub-bottom Profiling, Side Scan Sonar, Magnetic Survey and High Resolution Seismic.

Data processing functions are developed in MatLab2015b (https://mathworks.com/). Data loggers are developed in Free Pascal (http://www.freepascal.org/).

The Ge0MLib presents the comfortable space (predefined fields, variable’s structures, basic functions) for manipulations with geophysical and navigation data. The MatLab presents space for quick software development and compact code writing.

The specific Ge0MLib features are:
- the usable variables' structures for Geophysical Survey’s tasks decision;
- vessel with equipment can be regarded as a single object described math models (for example, some corrections in navigation sensors data can easy applied for all towing/mounting equipment’s position in sgy, jsf and xtf formats);
- easy access to each byte of Geophysical data;
- access to software source codes and algorithms (possibility for code modification);
- special tools for serial sensors’ data logging and synchronization.

The functions sets are shown in the Table below, linked to download page. The changes page is presented.
