Hydrography Download Service

Hydrographic information that meets the requirements for INSPIRE and the Swedish water standard. The product name in Swedish is Hydrografi Nedladdning.

Brief information

The service contains lakes and watercourses and associated information related to them, e.g. rapids, dams and waterfalls. The service also includes a geometrical network according to INSPIRE and a logical network according to the Swedish water standard.
The service consists of four information themes that can be downloaded separately:

  • Network according to the Swedish water standard
  • Physical waters according to the Swedish water standard
  • Network according to INSPIRE
  • Physical waters according to INSPIRE

As a fifth choice, in addition to the four themes mentioned above, a history file can be downloaded. It contains the changes that have occurred since the previous version of the product.

The product has nationwide coverage and is geographically divided into main drainage basins, coastal areas and Norwegian product areas. The delivery format is GML.

Objects related to Nationell strandlinje (NSL) (National shoreline) are found around the coast and the larger inland lakes. Where main drainage basins extend across national boundaries, information with limited cross-border content is included. Foreign data is delivered in separate files and can be visualized together with the Swedish data.

The download is provided as an Atom feed. There are many different clients, including browsers, that can read the Atom feed. Browser support for reading Atomic feeds varies, some have it built in support (FireFox up to version 60), for others a plugin is required to read the feed.

A browser is probably not the best client for retrieving data. Examples of a plugin that can read the feed, draw coverage polygons and download and draw the data in Inspire services can be found on RSSOwl (opens in a new window)

Here you can find films about our hydrography products and their applications (in Swedish).

How to retrieve the data

The service is primarily developed for machine-to-machine interfaces, an ordinary web reader can’t handle atom feeds. You can however download the product directly via some web readers if you install an extension.
For Chrome you can find such an extension here (in Swedish): https://chrome.google.com/webstore (new window)

For Firefox you can find such an extension here (in Swedish): https://addons.mozilla.org/sv-SE/firefox/addon/feed-preview/ (new window).

  1. Open the technical description for the service and copy the link for the access point Produktion (Production), then paste it into your browser.
  2. Choose the theme you are interested in, then select the area you want to download and finally the coordinate system in which you want data to be presented.
  3. Fill in your login details in the box that comes up.
  4. Unzip the downloaded zip file.
  5. Open the GML files in a software that can read GML files, such as QGIS.

Maintenance and update frequency

The information has nationwide coverage and is updated once per year.

Lantmäteriet updates basic geographic information at different intervals, using aerial imagery data, in accordance with The national image provision programme.

Objects included in the Nationell strandlinje (NSL) (National shoreline) are updated in collaboration with the Swedish Maritime Administration. 

Problem solving for QGIS

If you use QGIS, there is a problem that means that not all attributes in the logical network according to Swedish water standards become visible.

The Swedish water standard's page for XML schema files (new window) contains this link: http://resource.sgu.se/data/schemas/ss637008/example/example.zip (new window).

Via the link you can download a file with a description of how to handle this problem.

The file states, among other things:
"When the GML file is loaded, all xlink attributes are normally scaled away, which means that you can not follow the links in, for example, WS_FlowConnection. It is possible to load the GML file instead via a plug-in to QGIS (GML Loader) which allows the links to be loaded as separate fields or the attributes of the linked object to be included. The disadvantage is that the number of fields becomes extremely large because all the fields in the linked tables are displayed. "

In that case, you see all the fields, but the entire paths are then displayed in the attributes.

If you use QGIS, there is also another problem you should be aware of and that is that the attributes hydroID in WatercourseLink (polygon) and Standing Water, as well as relatedHydroObject in WaterCourseLink are NOT displayed in QGIS.


Our geodata services are normally available around the clock and we provide support during the day.

The versions of the services may overlap, so pay attention to which version you pick up at home. Version history describes the changes that occurred at each update.

Current versions:

    Technical framework and standard for download services

    Download services are based on the standard protocol WCS (new window) from OGC or the web standard Atom (new window).

    WCS works as a display service, but with the ability to download the data contained in the service. Most GIS software on the market has built-in support for the WCS standard .

    Atom is an XML-based format used for web feeds and can be used in most RSS readers or feed readers.

      Version history 

      Version and date

      Changes compared with previous version

      Version 1.1

      Available in verification environment:

      Available in production environment:

      The change does not involve a new access point or version.

      All areas are updated.

      The boundaries of some main catchment areas, coastal areas and Norwegian product areas have changed slightly.

      In the theme Swedish water standard, physical water, channels are now reported in RiverReach, via the origin attribute.

      Shoreline to sea and closure to sea are now reported only in coastal areas, applies to both Inspire and water standard themes.

      Version 1.1

      Available in verification environment:

      Available in production environment:

      The access point is the same as before, as well as the version.


      Correction of the previouos release, so that the wrong type of identifier no longer is used. In the previous release, both regarding Inspire and the Swedish water standard, some lakes and watercourse surfaces had ”aceid” as identifier instead of ”vattenytaid”. That is now corrected.

      In the Swedish water standard the value
      ”-999” is presented in the attribute ”elevation” in StandingWater when no elevation value is available. This is done to avoid possible risk of inconsistent attribute names when QGIS is used.

      Version 1.1

      Available in verification environment:

      Available in production environment:

      The change means that a new access point needs to be used. Please look over the systems or applications that connect to this version.

      All areas have been updated.

      In the theme regarding the swedish water standard the following changes have been introduced: MainRiver instead of RiverReach, RiverReach instead of RiverReachSegment (line) and WaterSubSystem instead of RiverReachSegment (polygon). Also presented are Outflowlocation and aqueduct (Crossing), the latter has also been introduce in the Inspire theme. More attributes have also been introduced, in both the swedish water standard themes and the Inspire themes.

      A history file is also available in the product, containing id’s for the lakes, water courses, centre lines and indistinct centre lines where the geometry have been changed since the last release.

      Version 1.0.1




      All areas have been updated.

      The following three changes, introduced for a smaller number of areas in the previous release, have now been introduced in all areas:

      • The detail type Vattendrag under mark (Watercourse below ground) have been recoded into the detail type Stomlinje otydlig (Centre line, fictitious).
        - In the Inspire themes the geometric network remains intact. However, Vattendrag under mark (Watercourse below ground) will no longer be presented in the layer Watercourse, since Stomlinje, otydlig (Centre line, fictitious) is not coded to Watercourse, which Vattendrag under mark (Watercourse below ground) previously was.
        - There will be no consequences at all in the Swedish water standard themes. Thus, the logical network remains intact.
      • The detail type Blekvät (Lime stone bog) has been re-coded as Sankmark, svårframkomlig (Wetland, difficult to pass).
        - In the Inspire theme Wetland and in the water standard theme WS_WetlandWaterBody, Blekvät has been coded as Sankmark svårframkomlig (Wetland difficult to access) in the attribute local Type.
      • The detail type Dambyggnad (Dam building) has changed from only referring only to the part of the dam that carries the dam hatches to the entire dam structure. The change affects approximately 300 dam buildings. 

      In addition to the above, the following corrections have been introduced: 

      • Errors have been corrected in the network in accordance with the Swedish water standard, where earlier stomlinjer (central lines) in watercourse surfaces have disappeared from the network.
      • The attribute beginLifespanVersion, is now handled in the same way in the Swedish water standard as in Inspire. The attribute gets a new date even when an existing object's geometry has changed and not just when a new object is created or when an existing object's attribute has changed.
      • Some shorelines in the coastal areas have previously been missing in the Inspire theme for physical waters. This is now corrected.
