Basemap Data

The Norwegian Polar Institute offers downloads of the official topographical basemap datasets for Norwegian polar land areas, under these terms of use. The data are either scale independent or created for best visual appearance when printed at selected map scales (see description column). The data are provided in the most commonly used GIS file formats, to be used e.g. to create custom maps or to do analyses. NOTE: The downloads are not maps, but rather map data which can be used to create maps from scratch in GIS software. Click the links below to go to data product page for metadata and data downloads. Partners in Norway digital (Norge digitalt): Please download data from the Geonorge website instead.

Basemap Services

The Norwegian Polar Institute offers a selection of cached and dynamic basemap services which can be consumed to create interactive web mapping applications or as layers in desktop GIS, under these terms of use. The cached services are tiled map services which are maps that have been predrawn by the server at defined scales (zoom levels) and stored as graphic files to serve maps fast. The dynamic services are WMS services, which return map images as requested by the user, consisting of the active map layers, map extent and zoom level at the client side.

The cached services can be used in clients with support for ArcGIS Server tiles such as OpenLayers, Google Maps or Esri's JavaScript API in the same way as Google Maps or Esri Maps is built up. Read the developer's guide on how to create web applications with those basemaps.

The dynamic services, as well as the cached services, can be added as layers in most mainstream GIS software, such as described here for ArcGIS and QGIS.

Cache zoom levels and scales

To easily combine cache from different services in the same map window, it is an advantage to have a common definition of the geographic area that defines the service. Because the cached services have fixed zoom levels, the service can not deliver tiles that lies between two defined zoom levels.

The table below shows the zoom levels, scales and resolutions for the cached services at the Norwegian Polar Institute (except the EPSG:3857 service). These are the same as in the Norwegian Mapping Authority caches for mainland Norway.

Image formats and coordinate systems

Services are available in two image formats:

  • Image / jpeg (does not support transparency)
  • Image / png (supports transparency)

Tile size for jpeg is about 1/3 of the png so it must be considered what is important, speed or support for transparency. The image tiles have a resolution of 96 dpi with a size of (256x256 pixels).

Thematic Map Services

NPI delivers a wealth of thematic maps as dynamic map services. Dynamic map service is a service where a server request to send map section in the form of raster files back to the user, either directly in the browser, a web application or a desktop application.

Dynamic services based on WMS specification are flexible and provides the user with many options, such as:

  • Choosing which map projection will be produced in
  • Turn on or off layers in the service.
  • Choose scale freely
  • Which image format and transparency to be produced
  • Retrieving Legend of the various map layers
  • Obtaining basic information about objects on the map from attributes (feature info) etc

All services are published on NPI's map services directory.
