Engineering Analysis Module

Channel Maintenance Has Never Been Easier

Simplify decision-making by using the Engineering Analysis Module, the scalable and interoperable enterprise solution for infrastructure management based on CSAR datasets. Effectively manage navigation channels, waterways, and ports, including vertical walls, comparing to models and performing analysis.

With this solution, you can:

  • Analyze bathymetric data's conformance with theoretical models
  • Create models or use existing models defined in the open LandXML specification
  • Use models to create raster surface representations of your infrastructure, such as quay walls, to detect deformation
  • Compute the amount of material that has been removed or added to analyze maintenance work that has been done
  • Use the powerful 3D visualization engine to identify areas of dangerous sedimentation and then publish reports of these shoal areas

Discover these and other tools, including profiles, differences, and linear referencing, all designed to provide the best engineering and analysis experience.

The Engineering Analysis Module can be licensed with the Bathy DataBASE suite or the standalone BASE Editor application.

Feature Highlights

Here are the some notable feature of Engineering Analysis Module

Vertical and Inclined Modelling and Analysis

Comparing the state of your infrastructure to a model, and comparing the state between surveys, is an important task. For vertical or steeply inclined walls like quay walls, it is vital to monitor to ensure that pressure from the surface is not causing deformations in the wall, and the base of the wall is not eroding over time.

Existing proven raster surface tools can now be applied even in these cases, provided that a suitable raster surface can be created. EAM allows using vertical or sloped surfaces as coordinate referencing systems to create these raster surfaces. Then existing tools, such as differencing raster surfaces and viewing the profiles at regular intervals, can be used to perform analysis on this data. This results in increased efficiency, and means that divers may only needed to perform targeted inspections where deformations have already been identified.

The vertical and inclined plane surfaces can be used in volume calculations and can be contoured creating true 3D lines that can easily be exchanged with other third-party applications. The addition of these tools allows for more complex workflows to be applied in deformation analysis of quay walls and other important infrastructure in ports and waterways.

Volumes Calculations

Calculating the amount of material above and below a model is a vital part of maintenance. Four types of computations are provided to suit your varied needs:

  • Rectangular Volumes is a quick way to get an approximation for a gridded surface
  • Hyperbolic Volumes calculates volumes on a smooth, realistic approximation of a gridded surface
  • Triangular Volumes uses the data's true positions, with a linear approximation between the nodes
  • Comparative Volumes determines relevant changes, and can be used to evaluate dredging and filling operations

All of these calculations work with 3D models or at a fixed depth, with an optional allowance below the model.

Conformance Analysis

Many engineering and maintenance decisions are based on how well the current data conforms to the existing model. When the two do not match, either the model needs to be updated or the terrain needs to be modified. In the waterways market, it is typical to report these areas to users of the waterway in a notice to mariner, and then a dredging contract is awarded to clear the hazard.

Decision-making is made easy with a number of views for comparing the data to the model:

  • Quickly get a 2D view of the areas that do not conform with a 2D colouring of the difference surface. This operation is completely configurable with any number of colouring ranges and can clearly and cleanly show which areas need to be addressed.
  • The 3D view is another easy way to visualize the areas where data encroaches on the model, especially when using the simple transparency settings.
  • With the linear referencing provided in reference models, creating regular vertical cross-section profiles of the data and model is just a matter of selecting each feature in a map. These profiles are suitable for displaying in reports and for further analysis against previous plots.

Shoal Management

Manage hazards with this configurable view of conformance. Designed to maximize the width of the channel that is available to vessel traffic, shoal detection facilitates the publication of simplified representations of hazardous areas.

Areas where bathymetry is above the model are marked, with additional areas created at every user-specified step above the model. These areas are covered by minimum bounding boxes, which can be automatically and manually merged to ensure the number of publications meets your needs. The more shoals at different depths are published, the more of the channel is available to shallow-draft vessels; the fewer shoals are published, the easier it is to manage the publications.

In the above images, the shoal areas are shown as red lines, and the minimum bounding boxes are shown by black dashed lines.

Additional metadata, such as the clearances between the shoals and the sides of the model, is calculated automatically when shoals are detected. Other metadata, such as the nearest reference feature, can be determined on request. The end result is a configurable shoal publication, with automated tools and manual overrides available at every step along the way.

Model Editing

In addition to supporting the open LandXML specification, the Engineering Analysis Module provides tools to create a 3D model of the maintained area with the reference model editing functionality in BASE Editor.

A typical 3D model includes horizontal areas bounded by side slopes at a given gradient. These can be defined based on an alignment with linear referencing (stationing), with the referencing based on straight and/or curved segments. Profile lines can then be automatically generated at fixed distances along the alignment.

Models can also be created from existing vector background maps, including S-57 ENC, CARIS, Shapefiles and many other formats.
