It enables governments, NGOs, utilities, contractors, engineers, and technical consultants to automate environmental compliance, identify risks and opportunities, quantify the impact of infrastructure projects or environmental change, track progress toward policy objectives and save time by seamlessly sharing data with partner organizations and public stakeholders. The platform integrates live data from virtually any source - including IoT sensors, geospatial datasets, photos, and web-scraped feeds - and transforms it into performant, interactive 2D and 3D maps and time-series charts that are always up-to-date. Users can simulate scenarios, calculate metrics or continously generate operational forecasts by deploying physics-based models, machine learning algorithms, or their own custom scripts directly within the digital twin. Secure APIs and open data portal functionality make it easy to share data and insights with partners, public stakeholders, and external tools. # Features ## Link map features with timeseries and photos Select any feature on the map to view its live sensor data, historical trends, associated properties or photos. This cuts investigation time from hours to minutes. ## Visualize in 2D or 3D Bring raster and vector data to life in 2D or 3D maps. Apply rule-based or data-driven coloring to map features to highlight locations with anomalies. Time travel to inspect historical states or modeled future scenarios. ## Explore time series with interactive charts Connect sensor measurements to spatial objects or regions and display results in interactive charts. Visualize thresholds to detect exceedances of safety, compliance, or operational limits. Chart configuration supports custom indicators, aggregation methods, and domain-specific layouts. ## Connect anything Integrate data from virtually any spatial format and protocol (KML, GML, GeoJSON, Geotiff, WMTS, WFS, HDF, NetCDF, Shapefile), photos, time series from IoT devices and sensors such as JSON, CSV, XML or semi-structured data from websites. Use one of the 200+ data sources already available in Nexus or bring your own. ## Always up-to-date Keep data at its original source and let Nexus connect to it to bring it to life. Maps and charts update continuously, ensuring the digital twin reflects the current state of assets and environments without requiring manual re-imports or refreshes. ## Operational forecasting and scenario analysis Get decision support by simulating based on live data rather than static model inputs. Deploy built-in or user-supplied calculations, such as scripts in any programming language, trained machine learning algorithms, or physics-based models. Supported use cases include: - Scenario modeling (“what-if” studies) - Policy and performance indicator generation - Compliance and safety limit evaluation - Spatial interpolation - Continous operational forecasting ## Work from anywhere on any device Access the digital twin in the field or in the office. The browser-based viewer runs on desktop, tablet, and mobile without additional software installation. ## Share data with partners and citizens Use Nexus as an open data portal, or securily connect Nexus to external applications through REST APIs or direct database connections for programmatic access. Supported ecosystem integrations include GIS platforms (ArcGIS Online, QGIS), BI and analytics tools (Tableau, Power BI), and Python workflows for custom processing and automation.
