Import 3vGeomatics Data

This feature allows users to import 3vGeomatics data to EX3. The sensor data is in *.csv format and this page will demonstrate how to import the data onto the results.

1. Select File > Import > Import 3vGeomatics Data or Interpret > Import Sensor Data > Import 3vGeomatics Data

After selecting the Import 3vGeomatics Data, a file selection window will be opened.

2. When a csv file in 3vGeomatics format is selected, it will to open an Import Window with some import options. According to the documentation from 3vGeomatics, they have three formats: Displacement with XO markers (the “x” and “o” indicates if the displacement result has been interpolated or not), Displacement without XO markers, and Instantaneous Velocity.
Currently only Displacement without XO markers is supported in this version of EX3.



The import options are listed below:

Reference Point Display/Selection View: Locates on the right side of the window. It displays the geometry point cloud in top view. There are buttons to allow users to translate or zoom in/out the view. Additionally, users can set the reference point (origin in the local coordinate) by selecting the point on the geometry. The selection updates the value displayed in Reference Point.

Reference Point: Locates in the first line on the window’s left side. It displays the current reference point in X and Y. The reference point is the first point in the file by default, and it is already converted to its local coordinate if the points saved as longitude/latitude in the file. The default value of reference point is (0.0, 0.0). The values displayed are accurate to four decimal places by default. The users can enter values to set the reference point according to their needs.

Properties: Locates below Reference Point. It contains all the available properties to import form the file. For now, Displacement is the only available option available.

Begin/End Date: Locates below Properties. It lists all the dates saved in the file and users can obtain the (displacement) values by the range of selected dates.

If users click the Cancel button, the import process will abort and return to the main window. When the OK button is clicked, it will move to the next stage.

3. In the Edit Point Cloud window, it provides couples of options to allow user to edit the point cloud, including translate, rotate, scale, change orientation and data filtering, and a viewport to preview the edited point cloud. Select OK to complete the edit.

The filtered points, whose value is out of range, are rendered in red color; while the unfiltered ones are in green color.

The default display mode is in Point Cloud, but users can set it to Solid Mesh in the Properties panel. The Properties panel is on the bottom left corner of the main window.

Select: View Options > View Mesh > Solid Drawing.

It automatically updates the views by rendering the geometry in solid mesh.

The users can maximize the view they want to keep by double clicking on the view and it will hide all the others for a better view. For example, here we only keep the 3D view, which is on the top right corner, and it looks like this:
