Step-by-step guide

Once CCTV survey data has been created or imported, the applicable InfoAsset Manager tools and options can be used to work with this data. For example, CCTV defect scoring can be used to judge pipe conditions.

Begin with a network containing CCTV survey data open on the GeoPlan.

To control the display of CCTV defects:

2. In the Properties and Themes dialog, select the CCTV Defects tab.

The Custom CCTV Code Display grid enables full control over which types of defects are displayed.

3. To show a specific defect type, select the checkbox in the Show column.

5. In the CCTV Defect Display group, select a general display option of Display Current or Display All.

The CCTV Grade Display group provides a quick way to control the Show settings in the grid.

7. For this example, select a Defect Grade of 1.
8. Click Set.

7. To set the defect symbol size, use the Size drop-down.
