This article explains how to interpret the Contours and use the Structure Elevations to determine the slope of the property and elevation at each corner of a design.
The contour and topography data in Canibuild is generated using LiDAR (Light Detection and Ranging) technology.

Toggle Contours – Displays coloured contour lines indicating changes in elevation. |
 |
Structure Elevations – Shows elevation levels above sea level at each corner of the structure. |
How to Check the Slope of the Property
- Click Toggle Contours on the main toolbar (Top Right).
-
Observe each contour line marked with a number or RL (Reduced Level), indicating height above sea level.
-
Use the colours to quickly understand elevation
Red indicates the Highest Point on the property
Blue indicates the lowest point on the property
Solid lines indicates a 1 m elevation change
Dotted lines indicates a 250 mm elevation change.
When contours are turned on, a notification will display the type of data:
-
Pre-existing contours, high confidence.
-
Pre-existing contours, low confidence.
-
Proposed contours (by the developer for a new subdivision).
-
Contours unavailable.
If contours are unavailable, a notification will appear at the bottom of the screen. This often occurs in new subdivisions. If you have a contour survey from the developer, please submit it to our team for upload.
Proposed contours outside the standard 1 m or 250 mm intervals are shown as solid orange lines.
How to Understand the Structure Elevations
-
Left-click on the design.
-
Select the Elevation icon from the Design Options.
The structure elevations show the change in height at the four outer most corners of the structure:
-
The Green point (A) is always the highest point.
-
The Blue points indicate how much lower they are than point A.
Click on any letter to view additional details:
- NGL – Natural Ground Level.
- FFL – Finished Floor Level.
You can edit the 0 value at Point A to simulate foundation height. For example, entering 0.3 will update the FFL to 300mm.
