4D digital twin platform

Your assets, element by element. Over time.

TEAL 4D connects 3D surveys, information and activities in one web environment. Each asset element has its own record, condition and history to follow over time.

Industries

One model, multiple industries.

Configurable element types, hierarchies and attributes adapt the data model to your asset. From cultural heritage to emerging applications in infrastructure, the environment and agriculture.

Available

Cultural heritage

Cathedrals, historic buildings and monumental sites. Materials, conservation condition and interventions linked to each element, supporting the work of technical teams and conservators.

  • Architectural and decorative elements
  • Monitoring, analysis and maintenance
  • Intervention records
In development

Infrastructure

A model for organising bridges and other structures into spans, piers and joints, linking inspections and interventions to each element.

  • Inspections by element
  • Monitoring between surveys
  • Sensor data on the 3D model In development
In development

Environment and agriculture

Applications in development to connect multispectral surveys, vegetation indices and monitoring campaigns, supporting agronomic assessments.

  • NDVI, NDRE, GNDVI, LCI, OSAVI
  • Comparison across surveys
  • Interventions by field
How it works

From raw data to asset management.

  1. 01

    Capture

    Start with your existing surveys or use QP DRONE's services to capture the data your project needs.

  2. 02

    Structure

    Organise your asset into elements, hierarchies and attributes, and link point clouds and 3D models displayed in the 3D Tiles format.

  3. 03

    Manage

    Link inspections, analysis and interventions to elements, with defined workflows and responsibilities.

  4. 04

    Track over time

    Connect surveys and interventions to the asset's history. Time is the fourth dimension.

The platform

Data, models and activities, in your browser.

Technical teams, researchers and managers access the same project through a browser, with assigned roles and permissions.

Web 3D viewer

Stream point clouds and meshes, with measurements and cross sections directly on the model.

Configurable data model

Configure element types, hierarchies and attributes for your asset through the interface.

Traceability over time

Changes to data are recorded to document how the asset evolves.

Workflows

Monitoring, analysis and maintenance, with clear status and responsibilities for each activity.

Teamwork

Multiple users working on the same project, each with their own role and permissions.

Excel when you need it

Update attributes in bulk directly from a spreadsheet.

From survey to management

One partner, from flight to digital twin.

QP DRONE, QP NOVA's survey division, captures the data. QP NOVA processes it and TEAL 4D links it to asset elements, keeping your work connected from one survey to the next.

Capture

Drone photogrammetry, multispectral and thermal surveys, planned around your asset and repeatable over time.

Processing

Point clouds, models and indices, processed, georeferenced and ready for the platform.

Management

Models, information and activities linked to asset elements, ready to be updated with each new survey.

Deployment and data

Your data stays yours.

Architecture, security and deployment requirements are agreed with your IT team before the project begins.

Dedicated deployment

An instance dedicated to your project. Deployment within your own infrastructure can be assessed with your IT team.

Open standards

Models displayed in 3D Tiles, the open OGC standard, with data export options.

Controlled access

OpenID Connect authentication, with roles and permissions assigned for each project.

Developed by QP NOVA

A platform developed in Italy, backed by direct expertise in the software and data management.

Our roots

Over a decade of research, one product.

TEAL 4D builds on applied research into surveying and managing built heritage, developed in collaboration with academia.
