Create survey work from drone data in a smart way

COMBINE DATA FROM DRONES, FIELD WORK, & CAD

Sometimes drone data is the only data source you need. Often, it is not. Add data from your field instruments (GPS or total station) to capture topographic features that cannot be observed from drones. Import civil designs from CAD and compare them with your drone data.



Give and revoke external access to your projects at any time through Virtual Surveyor desktop

Support for data formats coming from civil design, field instruments, photogrammetry and airborne LiDAR:
  • 1Orthophotos
  • 2Digital Surface Models
  • 3Point Clouds to DSM
  • 4Point Clouds to Ortho
  • 5Field Surveys
  • 6DXF/LandXML files



LOOK AT YOUR DATA FROM ANY ANGLE

An interactive 3D view is ideal when you want to understand a topography and/or compare it with a design. A 2D map view is often easier when you are mapping linear features or need to prepare a report. The 2D profile view helps you to understand how your topography has changed over time. Switch instantly between these views.





DIFFERENT SETS OF LENSES FOR BETTER INSIGHT

Often an orthophoto clearly displays the information you need to survey. Sometimes you want to look at the elevation only. Change the appearance of your drone data instantly through any of the 6 terrain lenses and visualize information that was hidden before.







Survey points with descriptors

POINT TOOLS
Measure, describe, and structure survey points directly from your drone data. Work with drone data the same way as a surveyor in the field!

Surveying curb and gutter with arcs and line offsets.



The low-pass intelligent gridding is an ideal tool to survey areas that have lots of vegetation.

GRIDDING TOOLS
Create survey points at regular intervals. Or use intelligent algorithms to place points at bare-earth or topographic breaks. Erase tools provide an easy way to make quick edits.
  • 1Regular point grids
  • 2Low-pass grids
  • 3Q-Point grids
  • 4Remove grid points

SURFACE TOOLS
Convert your survey points and linework to a lightweight CAD model of the topography. Display the surface as triangles for design, or contour lines for map purposes.
  • 1Quick surfaces
  • 2Triangulate surveys
  • 3Contour/TIN display
  • 4Remove triangles
  • 5Surface clipping

Triangulate breaklines and point grids together into a topographic surface.

Stockpile volumes

STOCKPILE TOOLS
Calculate volumes for stockpiles or basins. Works for free standing, walled and fully enclosed piles.
  • 1Stockpile volumes
  • 2Basin fill volumes
  • 3Volume annotations
  • 3Volume export
 Learn more on stockpile inventory



CUT-AND-FILL TOOLS
Compare progress over time between drone data, a design file or a baseline.
  • 1Cut-and-fill analysis
  • 2Spot heights
  • 3Volume/balance regions
  • 4Export cut-and-fill map
  • 5Create reports
Cut-and-fill analysis over a construction site


REMOVE MACHINES
Every drone survey comes with machines. Remove bulldozers, excavators, conveyors and other material on your site with a single-click. Ensure your cut-and-fill analyis only includes the bare-earth topography. 

Remove the bulldozer from the drone survey


FLATTEN WATER
Drone photogrammetry produces noise over water. LiDAR data from drones typically show holes over water. Remove these artifacts easily with the water tools and flatten water in just a few mouse clicks.

Remove noise from water by levelling the elevation to the extracted water level


MODIFY TERRAIN
Level your elevation terrain to any reference level you import or create. Triangulate a reference surface from a boundary. Adjust to the proper elevation, include breaklines or automatically extract a flat elevation value.

Create a baseline by removing stockpiles by levelling them to acreated or imported reference level.


Extract a water level with a single-click.

WATER
Simulate a water level on top of your drone data and calculate the intersection with the terrain. Extract a water level in a single click.
  • 1Create water surface
  • 2Set water level
  • 3Extract terrain intersection
  • 4Calculate basin volume


FLOW DIRECTIONS
Enable the slope directions lens and see how the water flows through your current or designed topography. Learn more about terrain lenses

SPEED UP YOUR PRODUCTION PROCESS

Accelerate your survey workflows with the productivity tools in Virtual Surveyor. The software produces the bulk of the output. You only need to review, remove and add some points or breaklines to complete the job.


Extract breaklines by combining manual input and computer calculation power
Guided Breakline Drawing

Breaklines describe changes in slope and are very important when creating an accurate surface. Draw the first segment of your breakline to give direction and let Virtual Surveyor do the rest of the job for you. Watch how it's done!




Low Pass Points

The Low Pass filter is an ideal tool for placing ground points in complex landscapes like forested or urban areas. The algorithm does the bulk of the work and you provide the final edit. Watch how it's done!

Q-Points allow to quickly place points a breaklines
Q-Points

Q-Points are the most important points to describe your topography. The Q-Points algorithm places these points for you in minutes. You only need to review and make a few edits before making your final surface. Watch how it's done!
