Virtual Surveyor adds functionality for larger drone survey projects – GPS World magazine

Virtual Surveyor drone surveying and mapping software has added new functionality that enables users to process larger projects without buying more powerful computers or cloud services, according to the company. This addition is one of several included in Virtual Surveyor 6.2.

“Our objective with Version 6.2 is to make our users more productive while saving them money by eliminating the need to invest in new hardware or processing services,” said Tom Op ‘t Eyndt, CEO of Virtual Surveyor in Belgium. “We have addressed the fact that drones are capturing more data at higher resolution, resulting in enormous files sizes.”

According to the company, Virtual Surveyor 6.2 solves the problem of large files by offering enhanced clipping and mosaicking functionality. The new version allows users to merge multiple smaller processed pieces of orthophotos and digital surface models into a single project and create smooth edges between these pieces with the new clipping tool. The mosaic can then be exported to a new tiff file or serve as the basis for a full area virtual survey.

In addition, Virtual Surveyor 6.2 offers a 3D Fly Through capability that allows users to select spatial bookmarks and waypoints in their scene and create a movie that allows the viewer to fly through the terrain in three dimensions.

Virtual Surveyor 6.2 also features improved surface handling for volume calculations. This feature was developed primarily for users who measure volumetrics of material piles in drone survey data. This capability makes it easy to represent topographies as triangles, contour lines or outlines without creating three different objects, the company said.

Other enhanced features of Virtual Surveyor 6.2 include a renumbering tool that allows users to select a set of times, features or geometries in the data set and automatically number them sequentially from any chosen starting number; concave hull extraction that allows users to select a section line to create a surface for a curved roadway; and boundary selection that allows users to trace around an unwanted feature and delete that object and all the points within it.

“The advantage of Virtual Surveyor is that it combines the interpretation skill of a professional surveyor with computing power to create standard survey products,” said Op ‘t Eyndt. “Surveyors can now accomplish more in Version 6.2 without expensive upgrades to other aspects of their workflow.”
