Scope of works
• Conduct detailed topographic surveys
• Quality assurance and processing of the raw data
• Prepare plan, profiles and crosssections of the
streams, major valleys and drains.

Plans, Profiles and Cross
Sections

4. • Spatial and non spatial
datasets
• Detailed collection of
points along the drains at
10m intervals
Data collection

5. Data quality assurance
• Remove of all float points
• High PDOP values (above 4)
• Check for conformity to standard codes
• Overlay analysis of the data points with Orthophotos &
DEM’s

6. Plan and Surface

7. Plan and Surface
• Import the field data
• Create point groups
• Build a surface
• Create contours
• Quality assure the
contours

8. Creation of a profiles
• Invert profile
• Surface profiles
• Superimpose the surface
on the invert profile
• Quality assure the Profiles

9. Creation of a cross sections
• Sample lines along the
alignment
• Create cross sections at
10m intervals
• Quality assure the cross
sections
