MGISS launches new version of augmented reality web app

23 February 2020

UK geospatial specialist MGISS has released a new version of its web app TopoGrafi which allows for the display of 3D data in real-world models.

TopoGrafi is an end-to-end platform for capturing buried asset data and processing it for visually impactful and interactive augmented reality (AR) visualisations. Aimed at the utility and infrastructure sectors, TopoGrafi is already helping organisations in water and highways sectors enhance asset location data, improve on-site safety and reduce construction and maintenance costs.

Mike Darracott, managing director and founder of Liverpool-based MGISS, said: “TopoGrafi provides a single platform that allows data capture applications and augmented reality visualisations to use the same 3D coordinate system, also allowing for additional integration with high accuracy base maps and other data layers.” 

Many field-based data collection tools only project in 2D, which is why MGISS developed the unique TopoGrafi solution to display 3D data in real world models. Designed to be used alongside apps such as Esri Collector for ArcGIS, the TopoGrafi platform uses data from low cost, high accuracy, on-demand positioning services – GNSS (Global Navigation Satellite System).  

TopoGrafi applies near-real time conversions transforming the recorded positions to local reference systems aligning it with high accuracy mapping including Ordnance Survey MasterMap. 

The TopoGrafi toolkit also includes functionality to “snap” 3D features to each other and to other spatially referenced data to create a true 3D model which can then be used to create AR visualisations accessible from the desktop or in the field.
