Transitioning LiDAR Processing Workflows: From MicroStation to the Terrasolid Spatix Platform

For decades, Terrasolid applications (TerraScan, TerraMatch, TerraModeler) have relied on Bentley MicroStation as their underlying CAD engine. However, the introduction of Spatix—a lightweight, purpose-built CAD engine developed specifically for Terrasolid—represents a major shift in geospatial software delivery. This paper explores the technical motivations behind Spatix, its impact on LiDAR classification workflows, and the benefits of a standalone environment for geospatial analysts. 1. Introduction: The Evolution of Terrasolid

Terrasolid is widely recognized as the market leader in processing airborne, mobile, and UAV LiDAR data. Traditionally, these tools operated as add-ons to MicroStation. To provide more flexibility and lower the barrier to entry, Terrasolid developed Spatix—a platform that allows users to run the same professional-grade tools without the overhead or licensing requirements of a third-party CAD system. 2. The Spatix Engine: Technical Overview

Spatix was designed to mimic the core functionalities of MicroStation required for point cloud visualization and vector drafting while stripping away unnecessary features.

Decoupled Architecture: Terrasolid developers isolated the CAD interaction layer, allowing dialogs and settings to function as native Windows elements.

Visualization Capabilities: It supports 3D terrain modeling, surface generation, and high-performance point cloud rendering.

Native Integration: Spatix is included in the Terrasolid software price, offering a "simpler delivery" and a unified installer for new evaluations. 3. Key Advantages for Geospatial Workflows

The shift to Spatix offers several operational benefits for mapping professionals:

Accessibility: New customers can evaluate the software without purchasing a separate CAD license, significantly reducing initial setup costs.

Specialized Filtering: Spatix-based algorithms have proven highly effective in complex environments. For instance, recent studies in snow cover monitoring identified the Spatix-based algorithm in Terrasolid as the most reliable method for snow-free ground filtering.

Interoperability: Users can run both MicroStation and Spatix on the same machine using a single license, facilitating a smooth transition for existing teams. 4. Application in Modern Surveying

Modern LiDAR projects—ranging from UAV-based forest mapping to mobile mapping with vehicle scanners—require robust feature extraction. Terrasolid on Spatix maintains the full suite of classification tools, including:

TerraScan: Ground point classification and point-by-point editing.

TerraMatch: Calibration and boresight adjustment for mobile and airborne systems. As the industry shifts toward cloud-native point cloud

TerraModeler: Creation of Digital Elevation Models (DEMs) and contour maps. 5. Conclusion

The introduction of Spatix ensures that Terrasolid remains adaptable in a changing GIS landscape. By providing a standalone platform, Terrasolid has successfully removed the dependency on external CAD software while maintaining the high-accuracy processing standards required for professional geomatics and remote sensing.

As the industry shifts toward cloud-native point cloud databases (such as PDAL with EPT or Cesium’s 3D Tiles), where does a proprietary desktop format like Terrasolid Spatix fit?

The answer lies in fidelity. Cloud formats prioritize visualization (what you see), while Spatix prioritizes engineering accuracy (what you measure). For civil engineers, surveyors, and forestry analysts who need millimeter-accurate point selection and classification, Spatix remains irreplaceable.

However, Terrasolid has begun bridging the gap. Newer versions of the Spatix engine support streaming from cloud storage (AWS S3 or Azure Blob) using a cached index. This means you can store your master Spatix file in the cloud, and your local TerraScan will only download the cells you need.

Bottom Line: Terrasolid Spatix is the most important LiDAR processing update since the invention of ground classification. It successfully bridges the gap between raw point clouds and intelligent infrastructure models. If you bill by the deliverable, not by the hour, you need this.

Title: An Overview of Terrasolid Spatix: The Powerhouse for Point Cloud Processing

Introduction

In the realm of LiDAR and point cloud processing, Terrasolid is widely regarded as the industry standard. While their flagship suite of tools (TerraScan, TerraModeler, TerraPhoto) is traditionally associated with Bentley MicroStation, the shift in software platforms led to the development of Terrasolid Spatix.

Spatix is the dedicated CAD platform designed specifically to host Terrasolid applications. It represents a pivotal evolution for the software, moving away from dependency on third-party CAD engines to provide a standalone, optimized environment for geospatial data.

This write-up explores what Terrasolid Spatix is, its key features, and why it matters to surveyors and data processors today.

Just like a hard drive, a Spatix file’s index can become suboptimal after thousands of edit operations. Use the Optimize Spatix tool (found in Terrasolid Utilities) to rebuild the spatial index. This should be done after major classification runs.

For a typical LiDAR production line, the Spatix workflow looks like this:
