The new era of surveying is transforming topographic map acquisition methods in many sectors, including mining and civil construction. In the past, topographic data had a point density of 1-5 meters using a theodolite or a total station, requiring more time and manpower. The latest tools, such as total laser scanners, drone photogrammetry, and LiDAR, can quickly obtain data with point densities down to millimeters. This increased density results in better 3D modeling, precision, and accuracy, but also leads to larger amounts of data for processing.
Currently, many software developers are competing in point cloud-based data processing in both the mining and civil sectors. Most of them provide separate software for processing point cloud data and then converting it into CAD format for further processing in other software.
In fact, the point cloud feature in GEOVIA Surpac has been around since version 6.8 in 2017, with support for LAS, XYZ, and ASC data formats. Another convenience is creating a DTM (Digital Terrain Model) from a point cloud, either as a 3D solid or a 2D mesh. GEOVIA Surpac also supports reading and writing OBJ data file format (including image texture format). OBJ is a geometry file format that is the standard output for many photogrammetry systems. In 2020, it was enhanced with point cloud classification, which can reduce noise from vegetation and buildings, and the inclusion of lexographic meshing, making it easier to form solids.
Public trust in GEOVIA Surpac software is proven by the large number of mining sectors that currently use GEOVIA Surpac for calculating and collecting volumes for payment and purchases. By continuously developing the software, Dassault ensures that GEOVIA Surpac remains up-to-date with advances in mapping survey tools and the various types of data produced. Loyal GEOVIA Surpac users can rest assured that GEOVIA Surpac will always keep pace with the latest developments in survey mapping.
