Meridata MDPS data processing and interpretation software

MDPS is a powerful package for integrated processing and interpretation of marine geophysical data

It allows

data to be concurrently processed, visualised and exported to surface modelling, CAD and GIS systems.

MDPS description

Fast and intuitive map interface

Being geographical by nature, marine geophysical survey data is most rationally accessed via a map interface. MDPS/Projector interface provides the tools for management as well as versatile and fast visualisation of survey data. It also functions as the gateway to raw sonar data.

All survey data and survey-related data is visualised as map layers.

Raw data is directly accessible via point and click on the map.

Automatic and interactive processing and analysis tools

Meridata MDCS data-acquisition software logs survey data as raw unfiltered observations. In MDPS post-mission processing, this enables the use of optimal settings and sophisticated spatial computations for best results.

MDPS includes interactive tools for data cleaning and interpretation of each different data type. MDPS/Point Cloud Cleaner fluently cleans large sets of bathymetry data, while MDPS/Profiler provides an expedient interpretation interface for seismic and sub-bottom profiling data.

Available processing modules

Bathymetry data processing

MDPS/Point Cloud Cleaner fluently visualizes in 3D and cleans large sets of bathymetry data.

MDPS/Point Cloud Cleaner allows fast access to and inspection of depth point clouds in finest detail. Its huge processing power and smart cleaning techniques enable efficient workflow to obtain clean point cloud datasets. It includes automatic, computer aided and manual methods for cleaning the stray depth points.

The intrinsic integrity of soundings can be evaluated efficiently using the integrity analysis tools.

MDPS can also quickly create 3D surface models and contour plots from MBES depth point clouds.

Multi-frequency sub-bottom profiling data interpretation

MDPS uniquely integrates marine seismic and sub-bottom profiling data of different frequencies, and allows a single combined interpretation to be made of, e.g., air gun, boomer, and chirp sub-bottom profiles in a single pass.

Interpretation is further aided by a number of productivity-boosting features such as survey line crossing interpretation, use of core sample data, and interpretation integrity checking function.

Side scan data processing and interpretation

Alongside bathymetric, sub-bottom profiling and seismic reflection data, MDPS offers efficient processing and visualisation of side-scan sonar data.

The ability to concurrently process survey data from multiple acoustic sources enables you to quickly obtain a full picture of both the seabed and the sub-seabed.

Ancillary data

Besides hydroacoustic survey data, MDPS seamlessly incorporates marine magnetometer and other observation data into the geophysical data processing workflow.

In the process every observation is given an accurately computed 3D position evaluated against user-specified quality criteria.

3D visualization

In order to get better understanding of the big picture, the optional 3D Viewer module can visualize sub-bottom profiles, their interpretations and a multibeam echosounder derived bathymetry model all in one view. It zooms and rotates with simple mouse actions.

While useful when checking interpretation of adjacent and crossing lines, the 3D Viewer can also be used to export images for reports showing the key findings of a survey in an easily understandable way.
