Introduction

The geo-sensor always provides relative coordinate values, which are based on a point zero (0,0,0).

If the start and endpoints (manholes, connection points or buildings (e.g. pumping stations) have been set manually via a map with an integrated coordinate system (e.g. DXF plot) or a GPS point layer (manhole layer in the SHP format), they automatically get the corresponding coordinate positions.

Use the module WinCan Map (2D visualization of pipe courses) to quickly set manholes and connection points at the desired location. The module WinCan 3D (3D visualization of pipe courses) will be used later on to get an additional three-dimensional view of the pipe course as it would look like in reality.

WinCan Map User Settings

General Settings

Similar to WinCan VX, Map is also a global solution, so again there is no one set of settings that works for everyone. To ensure good results in 3D Measurement projects, please pay attention to these settings in File → Settings options:

...

Also, there is a more user friendly ‘Theme for All’ for the other non-measurement layers:

Setting Up a Project

Launch WinCan VX, create the sections to be inspected and fill out all mandatory (yellow) fields. Next run WinCan Map and you will then automatically be asked for the corresponding projection system (e.g. Switzerland= EPSG:21781 or EPSG:2056; Germany= EPSG:4839 or EPSG:5243 etc.) as well as a DXF­ plot used as a reference layer. The latter one is useful for precisely positioning the manholes:

...

As soon as the DXF plot appears in the map panel you must proceed as follows to set the manholes on the map layer:

Go to the legend panel, select the layer WinCan_Manholes and hit the command Tools → Draw (1).

This is going to display the drawing panel at the right part of the Map interface (2).

...

Highlight the desired object from the group of available manholes, activate the function Tool → Snap to nodes and select the DXF-plot as the snapping layer (3):

...

Next activate the drawing tool Draw point (4), move the mouse pointer at the desired location on the plot and finally click to draw the manhole position. Mind the crosshair icon that clearly indicates which reference line of the plot the manhole is going to snap to.

The manholes now appear on the map and the corresponding coordinate values are saved in the database.

If a manhole does not yet exist in WinCan VX you can draw it in Map at the desired location on the DXF plot as a new point of the layer WinCan_Manholes. Mind that you have selected the DXF plot as the snapping layer.

Next, enter the appropriate manhole name into the dialogue box that pops up and confirm with the green OK button:

...

In both cases the manhole coordinates are automatically taken from the projection system the DXF­ plot is based on.

Make sure you placed the camera into the manhole where you want to start the 3D-measurement and switch back to WinCan VX.

Keep the Map interface open as it is going to show you the measurement progress in real time.
