DGD Tool - Surface, Alignment and Coordinate Tools

Overview

The DGD Tool - Surface, Alignment and Coordinate Tools gINT Add-In consists of a range of utilities for the processing and querying of 3D surfaces, alignments and tidal data.

1. Set Coordinate Chainage Offset Tool: Calculates the coordinates to/from chainage and offset based on alignment data.
2. Grid File Pre-processing Tool: Pre-processes surface files to produce perfect grids, slice up over sized grids, invert elevations and replace null values.
3. Set Elevation or Depth from Surface Tool: Sets the depth or elevation for a range table structures from 3D surfaces.
4. Set Seabed Elevation Tool: Calculates seabed elevation for each point based on water depth and tidal information.

How It Works

Once installed you simply select the Datgel DGD Tool from the gINT Add-Ins Menu. You can access the four tools below from this menu.

Set Coordinate Chainage Offset Tool

The Set Coordinate Chainage Offset Tool gINT Add-In allows the user to calculate the East/North coordinates for the records on the POINT table from the chainage/offset values of a pre-defined alignment name and vice versa.

Grid File Pre-Processing Tool

The Grid File Pre-Processing Tool gINT Add-in allows the user to:

• Pre-process a grid surface file to fill in the null regions to form a perfect rectangular outline with no holes
• Divide the source grid file into several smaller rectangular grid files to cope with larger surface files
• Invert data, i.e. multiply Z by -1

Set Elevation or Depth from Surface Tool

The Set Elevation or Depth from Surface Tool gINT Add-in allows the user to set an elevation or depth field of a project table in gINT from values in a gINT surface based on the PointID's East and North.

Example Usage:

• Define the natural ground elevation for a CPT or Borehole location tested through a reclamation, by querying a natural ground grid or tin surface
• Update a Geotechnical Unit table with the results of modeled surface generated outside gINT. This would allow you to display the exact modeled data on a borehole log or colour the stick on a fence diagram

Set Seabed Elevation Tool

Made specifically for boreholes that were drilled on locations where the water depth is constantly changing with the tide, the Set Seabed Elevation Tool gINT Add-in allows the user to calculate the seabed elevation for each PointID based on water depth and tidal information. This will update all records on the POINT table that have tidal date/time and tidal water depth information.
