EGK TerraScan — Professional Survey Visualization and Engineering Intelligence
Developed by EGK Microelectronic Solutions Group Sdn. Bhd., EGK TerraScan Engineering Edition is a professional survey data visualization and engineering review application designed for civil engineers, land surveyors, road contractors, infrastructure professionals, researchers, and technical specialists.
Transform supported LiDAR point clouds and RTK/GNSS survey datasets into an interactive workspace for point inspection, spatial review, preliminary quality assessment, and engineering measurements. Built with SwiftUI and SceneKit, TerraScan brings essential survey visualization and review tools together in an intuitive mobile application.
POWERFUL ENGINEERING FEATURES
Interactive 3D Point Cloud Visualization
Explore supported LiDAR datasets in an interactive 3D environment. Inspect spatial point distributions and review terrain and survey data visually.
LiDAR and Survey Data Import
Import supported point-cloud and coordinate datasets from compatible files through the iOS document picker. Review imported data directly on your device.
Survey Point Management
Browse, search, sort, and inspect survey points and their associated coordinate information.
Survey Data Quality Assessment
Run preliminary data-quality checks to identify non-finite coordinates, duplicate point labels, and potential elevation outliers for further investigation.
Engineering Measurements
Measure horizontal distances and elevation differences between selected points. Calculate planar polygon areas by selecting boundary vertices in the correct order.
Elevation Profile Review
Explore a quick-look elevation profile to support preliminary inspection of elevation variation across imported points.
Engineering CSV Reports
Export survey point information and basic quality flags into CSV reports for further review and use in compatible spreadsheet applications.
Survey Equipment and Format Reference
Consult the built-in reference guide covering major surveying equipment manufacturers and commonly encountered file formats.
Designed for Professional Workflows
TerraScan supports preliminary review workflows for road construction, civil engineering, land surveying, infrastructure inspection, utility mapping, and technical research.
FILE COMPATIBILITY
Supported import capabilities depend on the file format, version, structure, and data layout. The application includes LAS point-cloud reading, ASCII PCD support, basic XYZ/PTS parsing, and supported survey-coordinate text workflows. LAZ decompression, E57 decoding, and certain proprietary scanner formats require additional format-specific support and are not universally available.
Consult the in-app format guide for compatibility information before importing project-critical data.
LOCAL DATA PROCESSING
Select files through the iOS document picker and process supported datasets locally within the application. Maintain backups of original survey files and verify important engineering results against appropriate reference software and project specifications.
