Digitize Reality: Transform your mobile device into a powerful 3D scanner. Simply point and record to create professional-grade 3D models. Pair with a compatible RTK device for centimeter-level accuracy, precise measurements, and geolocated 3D reconstructions. Visualize the captured model in the app, upload and export, and view it in AR. New ArcGIS Workflow: PIX4Dcatch now streams ArcGIS data in realtime in AR to provide in-field operators full contextual information about the entire site including 3D reconstructions and attributes. Our capture feature generates complete and defensible georeferenced 3D reconstructions which can be communicated seamlessly back to ArcGIS. New Guide-To Feature: PIX4Dcatch has a guide-to feature directing users to specified geolocated assets for staking, boosting onsite efficiency and accuracy. Just select the point or reconstruction you would like to find and follow the arrows in AR. WORKFLOW 1 – Scan & Capture Walk around your site. The app automatically gathers data and provides live feedback using iOS LiDAR, ensuring you capture every detail. For enhanced accuracy, use an RTK device compatible with PIX4Dcatch, PIX4D Autotags with a fully automated workflow, or combine both. 2 – Process, Analyze & Share Process your data by uploading to PIX4Dcloud for online analysis and sharing, or export to PIX4Dmatic for desktop processing. Both platforms offer a 14-day free trial. Projects can also be exported to third-party photogrammetry software. Measure spaces, document results, and enjoy all the benefits of a detailed 2D/3D model of your surroundings. 3 – View in AR Experience an immersive augmented-reality view. Display 3D models and points directly in your phone camera in AR. ____________________ USE CASES • Digitize construction sites • Measure stockpiles and other objects • Document underground utilities • Digitize indoor and outdoor spaces with Autotags • Visualize and verify 3D models in AR in real time • Perform single-point measurements with RTK accuracy ____________________ COMPATIBILITY • Optimized for LiDAR-equipped devices (Pro series phones) • All ARKit-enabled devices • RTK devices: Emlid Reach RX and RX2, TopCon HiPer CR, Bad Elf Flex Mini, Bad Elf Flex, Trimble DA2, Leica Zeno FLX100 ____________________ TERMS OF USE https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Proceq GPR Subsurface: Powerful sensors with radar beams for subsurface mapping applications. Intelligent software at your fingertips. The mission behind Proceq GPR Subsurface is simple: Scan the underground to provide a clear 3D image of what lies beneath, to detect and map the findings effortlessly and reliably, and to collaborate anywhere, anytime, for utility strike prevention, as-built map verification, structural investigations and various geophysical applications. The revolutionary Proceq GS series is the world’s most advanced subsurface mapping system, equipped with Stepped-Frequency Continuous-Wave (SFCW) technology and precise GNSS positioning. The true-ultrawideband antenna system and Swiss-made, optimized electronics deliver unparalleled resolution and penetration depth - at the same time. The magic starts once you connect the GS9000 or GS8000 wireless to your iPad and fire up the Proceq GPR Subsurface app. The carefully designed user interface increases your productivity by making measurements and analysis simple and intuitive; for example, by switching between top and sectional views with a simple gesture. A rich feature set brings advanced workflows on-site, so that you can get more things done while in the field. See the heatmap of the subsurface form in front of your eyes at the specified depth range, annotate your findings with precise geolocation, tags, photos, voice memos and comments in the logbook. Access and share them with colleagues anywhere, anytime, and export your measurements in one click, in the form of rich reports, the most common CAD/GIS mapping formats, or raw data for further processing, all over the cloud. Detect utility lines and label them accordingly to produce as-built maps, or digitize any other findings on the ground. Get an instant understanding of what is below your feet with the revolutionary Free Path 3D real-time visualization, or superimpose your area scans onto the real world with Augmented Reality - unique features in the industry. Download the free app now and explore the state of the art of subsurface mapping with the included demo files.

Verdict

The call

The clearest difference is in-app purchases: Proceq GPR Subsurface at none against PIX4Dcatch's 1. Proceq GPR Subsurface also leads on rating (5.0 vs 4.7) and review sentiment (50% vs 33%). PIX4Dcatch's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (262 vs 3). On price, ads, monetization model and device support there is nothing between them.
