PIX4Dsurvey is a powerful photogrammetry and point cloud processing software developed by Pix4D, designed to bridge the gap between photogrammetry, LiDAR, and CAD/GIS workflows. It enables surveyors, engineers, and geospatial professionals to efficiently extract critical vector data from point clouds and imagery, transforming complex 3D data into actionable, CAD-ready deliverables. The software supports large datasets and integrates seamlessly with other Pix4D products and third-party tools, making it a versatile solution for surveying, mapping, and construction applications.
Key Features of PIX4Dsurvey
Data Capture and Import:
Capture images or point clouds using drones, laser scanners, or LiDAR systems.
Optimize drone flights with the free PIX4Dcapture mobile app for automated data collection.
Import point clouds from PIX4Dmapper, PIX4Dmatic, PIX4Dcloud (.p4d, .p4m files), or third-party sources in .las or .laz formats.
Merge multiple datasets (photogrammetry and LiDAR) into a single project for comprehensive analysis.
Vectorization and Data Extraction:
Vectorize point clouds into points, polylines, polygons, and catenary curves with intuitive tools.
Extract key elements like curbs, building footprints, walls, and road markings with minimal clicks.
Use Smart Grid to automate spot elevations, simplifying point clouds by identifying terrain changes.
Access original images via Pix4D’s rayCloud to refine vectorization in 2D and 3D views.
Terrain Modeling:
Generate Triangular Irregular Networks (TINs) to model terrain accurately, creating Digital Terrain Models (DTMs) in LandXML or GeoTIFF formats.
Apply Terrain Filter to classify point clouds into terrain and non-terrain classes.
Create contour lines with short loop control for enhanced LiDAR compatibility and exportable outputs.
Integration and Export:
Seamlessly integrate with CAD and GIS software, exporting vector layers with custom properties in formats like .dxf or LandXML.
Export simplified, accurate data with reduced file sizes for efficient workflows.
Import and edit DXF files while preserving layer structures for contextual analysis.
Advanced Tools and Automation:
Automate road marking detection for single, dashed, or double lines, streamlining road surveying.
Perform volume measurements and generate detailed PDF reports with site images and inventories.
Use object detection to identify features like manholes and drains, even in low-resolution point clouds.
Scalability and Performance:
Handle billions of points across multiple point cloud files in a single project.
Optimized for large datasets with a lightweight point cloud display and fast processing.
Available in multiple languages (English, Spanish, Japanese, French, Chinese) for global accessibility.
Workflow Flexibility:
Supports both Windows and macOS with floating licenses for use across devices.
Offers monthly, yearly, three-year, or perpetual licensing options, with a free trial available.
Provides tools for manual and automatic point cloud classification, including ASPRS standards.
