About NLive

NLive is a system developed by NORCE that enables high-performance visualization of georeferenced and timestamped datasets in 3D on a virtual globe. The system can display both realtime and timeshifted datasets combined with different map and object layers, such as points or buildings. The timeseries come from many different sensors and instruments, including cameras, hyperspectral imagers and laser scanners integrated with drone flight telemetry, AIS or transponder data, air quality measurements, and more. The system is highly extensible and adaptable, enabling integration with new datasets and data sources in an efficient manner.

Windfield-hdr — Windfield reconstructed from SAR satellite data

RESICE-hdr — Realtime drone visualization with optical and IR cameras combined with Sentinel 2 satellite image

Coastal-hdr — Coastal monitoring with streaming video and AIS data

EGMS-hdr — European Ground Motion Service, about 10 billion points with associated timeseries

Applications

NLive is used to visualize large-scale ground deformation datasets computed using interferometric SAR data from satellites. It provides the front- and backend to InSAR Norway and the European Ground Motion Service.

Research

NLive has been and is actively used in multiple research projects at NORCE, including the ESA-funded Cryosphere Virtual Lab and EU's Horizon Europe-funded M4Mining project. NLive is also used internally at NORCE when conducting flight campaigns with either drones or the manned NORCE research aircraft (LN-UAV) or Lufttransport's LN-LYR.

Examples

The following links will open NLive with a preconfigured view and timestamp to show some datasets that have been gathered throughout the years:

RESICE drone flight in Ny-Ålesund on Svalbard. The flight campaign included realtime, onboard processing of optical and infrared camera images to detect ice bergs in Kongsfjorden.
RADAR tracking and streaming video. This flight demonstrates visualizing onboard RADAR data combined with streaming video from a gimbal-mounted camera.
Coastal monitoring with a drone equipped with a streaming, gimbal-mounted video camera and AIS receiver.
Ice drift monitoring and tracking using a drone from the Kronprins Haakon research vessel.
Visualization of temperature and other meteorological data from a drone flight conducted at Elvenes in Inner Troms. Customize the visualization by modifying the settings for the Hanoi instrument in NLive's settings.
Manned flight with LN-UAV to capture optical and hyperspectral data of basking shark.
Air quality monitoring using fixed sensor stations in Kvinesdal, Norway.
