The importance of handling survey correctly
Anyone can do it? A surveyor should do it ! Sometimes a road designer
inherits it A design is only as accurate as
the survey

SURVEY ACCURACYA design is only as accurate as the survey
PAV 1 - +/- 0.01m (point) PAV 2 - +/- 0.025m (point) PAV 3 - +/- 0.035m (point) PAV 4 - +/- 0.05m (point

Traditional Methods of Import to InRoads (from CAD)
1. Triangles 2. Spots and Breaklines3. Generic names off feature4. By Feature Style with intelligence

Traditional Methods of Import to InRoads

Summary of Import Methods
1. Triangles-inefficient, non intelligent but quick
2. Spots and Points-non intelligent and quick
3. Generic names off feature – quick and non intelligent
4. By Feature Style – arguably time consuming but with intelligence

Survey Composite (Model 2 - Step 2)
Merge Feature Photogrammetry Plus Topography
5 Feature plus 3 Photogrammetry plus 1 topography

Handling of Survey is a key component of any Project
Allow to resource it- do not underestimate the task
Make the most of correctly forming models with named features
Make the most of the Import Surface Advanced function
