About
PIX4Dsurvey is purpose-built surveying software developed in collaboration with professional surveyors to bridge the gap between raw point cloud data and CAD-ready deliverables. It supports importing point clouds from PIX4Dcloud, PIX4Dmatic, PIX4Dmapper, or any third-party .LAS or .LAZ file, allowing users to combine multiple datasets—including aerial photogrammetry and ground-based LiDAR—into a single project. The software's core strength lies in its vectorization engine: users can extract points, polylines, polygons, and catenary curves directly from point cloud data, verified against captured imagery for accuracy. The Smart Grid feature automates spot elevation extraction by reading the terrain class at key locations, saving thousands of manual clicks and cutting vectorization time by up to 50%. PIX4Dsurvey also supports TIN (Triangulated Irregular Network) generation for terrain modeling and exports DTMs in LandXML format. Volume measurement tools let users calculate volumes of any object—including against walls or in corners—in just a few steps. Custom layers and properties ensure smooth, direct export to CAD and GIS environments, reducing file size and preparation time. Ideal for land surveyors, civil engineers, and geospatial professionals, PIX4Dsurvey is available in 11 languages and works as part of the broader Pix4D ecosystem or as a fully standalone solution for any LiDAR or photogrammetry workflow.
Key Features
- Multi-Source Point Cloud Import: Import point clouds from PIX4Dcloud, PIX4Dmatic, PIX4Dmapper, or any .LAS/.LAZ file, and combine multiple datasets—aerial and ground-based—into a single project.
- Intelligent Vectorization Tools: Extract points, polylines, polygons, and catenary curves directly from point clouds with built-in tools, verified against captured imagery for precision.
- Smart Grid & TIN Modeling: Automate spot elevation extraction with Smart Grid and generate Triangulated Irregular Networks (TINs) to model terrain accurately, saving thousands of manual clicks.
- Volume Measurements: Calculate volumes of any object—including those against walls or in corners—in just a few steps with fast, simple measurement tools.
- CAD & GIS Ready Export: Export projects as vector files with custom layers and properties in LandXML and other formats for direct, lightweight integration into any CAD or GIS software.
Use Cases
- Land surveyors extracting 2D/3D vector elements (curbs, building footprints, walls) from drone-captured point clouds for CAD deliverables.
- Civil engineers creating accurate Digital Terrain Models (DTMs) in LandXML format from LiDAR or photogrammetry data for infrastructure planning.
- Geospatial professionals combining aerial photogrammetry and ground-based laser scan data into unified, CAD-ready survey projects.
- Survey firms calculating earthwork or stockpile volumes directly from point cloud data without needing additional software.
- AEC teams streamlining the transition from raw field scan data to GIS-compatible vector layers with custom properties and reduced file sizes.
Pros
- Major Time Savings: Users vectorize up to 50% faster by combining point cloud data with image verification, and the Smart Grid eliminates thousands of manual clicks for spot elevations.
- Flexible Data Compatibility: Works with any .LAS or .LAZ file and integrates natively with the full Pix4D product suite, making it versatile for both aerial and ground-based survey data.
- Smooth CAD/GIS Transition: Outputs are immediately usable in major CAD and GIS platforms with custom layers, properties, and reduced file sizes—minimizing post-processing effort.
Cons
- Paid Subscription Required: PIX4Dsurvey is a commercial product; full access requires a paid license, which may be a barrier for smaller teams or individual freelancers.
- Pix4D Ecosystem Dependency for Best Results: While it accepts standard .LAS/.LAZ files, the most seamless workflows are achieved when using other Pix4D products for data capture and processing.
- Desktop-Only Application: As a standalone desktop application, it lacks fully browser-based access, requiring software installation and sufficient local hardware resources.
Frequently Asked Questions
What point cloud formats does PIX4Dsurvey support?
PIX4Dsurvey supports .LAS and .LAZ point cloud files from any source, as well as native project files from PIX4Dcloud, PIX4Dmatic, and PIX4Dmapper (.p4d or .p4m).
Can I use PIX4Dsurvey without other Pix4D products?
Yes. PIX4Dsurvey is a standalone application that can work with any LiDAR or photogrammetry point cloud in .LAS or .LAZ format, independent of the rest of the Pix4D ecosystem.
What CAD and GIS software is PIX4Dsurvey compatible with?
PIX4Dsurvey exports vector files with custom layers and properties compatible with major CAD platforms (such as AutoCAD and Civil 3D) and GIS software, using industry-standard formats including LandXML.
How does the Smart Grid feature work?
Smart Grid reads the terrain classification of the point cloud and automatically identifies locations of elevation change—similar to how a field crew takes spot elevations along breaklines—eliminating the need for thousands of manual clicks.
Is a free trial available?
Yes, Pix4D offers a free trial of PIX4Dsurvey so users can evaluate the software before purchasing a full license.
