InSAR Norway
This web portal presents information about ground deformation of Norway generated by analyzing long time series of radar satellite imagery as part of the "InSAR Norway" project. See www.insar.no for more information.
Terms and conditions
The data and services offered by the Geological Survey of Norway (NGU), together with its partners, within the InSAR Norway project, are made available under the Norwegian Licence for Open Government Data (NLOD) 2.0. By using "InSAR Norway" services, you automatically consent to these terms. The service contains modified Copernicus Sentinel data (2021).
Project attributions
- The InSAR Norway project is managed and coordinated by the Geological Survey of Norway.
- The project is cofunded by the Norwegian Space Center and the Norwegian Water Resources and Energy Directorate.
- The service is powered by NORCE Geo Viz developed by NORCE Norwegian Research Centre AS.
Data attributions
The service uses terrain and map data from several sources:
- Geological Survey of Norway
- Norwegian Mapping Authority, GeoVekst and Counties (terrain data, topographic raster map and orthophotos over Norway)
- Copernicus Programme: European Union and European Space Agency
- Radarsat-2 data provided by Norwegian Space Agency/KSAT under the Norwegian-Canadian Radarsat agreements, 2009-2018
- Blue Marble: Next Generation; NASA Earth Observatory

Add WMS or WMTS layers
Enter the URL for a WMS or WMTS server below and click Add WMS or Add WMTS depending on the server type. Note that any custom WMS/WMTS servers added here will disappear when the page is reloaded.
No servers added yet.
Requirements
To use an external WMS or WMTS server, the server must meet the following requirements:- Support the necessary CORS-headers
- Support secure HTTP
- Support delivering imagery in Web Mercator projection (EPSG:3857, EPSG:900913)
The visualization's support for WMS and WTMS servers has some shortcomings, some of which may result in a given server not working even if it meets the requirements above. If you experience problems, simply reload this page.

Plot window
To open the plot window, click a point or select a group of points. The plot window will appear once data for the point(s) have been fetched from the server. To plot multiple single points, hold down the Shift-key while clicking each point. (Note that the summary display above the plot and the data table will only contain data from the last point clicked.)
- Hover the cursor over points in the plot to show their value.
- Click-and-drag to move the plot.
- Zoom the plot by scrolling in or out.
- Hold down the Shift-key while zooming to lock zoom to the Y-axis.
- Hold down either of the Command, Control or Alt keys to lock the X-axis while zooming.
You can also toggle connecting lines between each datapoint, points, select a curve to fit to the data and set a fixed limit on the Y axis from the popups at the bottom of the plot. Click the View Data button to show raw data for the last selected point. The plot shown can be exported as an SVG.
