Consultants using SCALGO Live Sweden now have the option to specify if their client is a member of Geodatasamverkan or not. When a user tells SCALGO Live that their client is a member of Geodatasamverkan no costs are incurred for the data accessed while this setting is enabled. It is the responsibility of the user to set this switch correctly as we are unable to retroactively change this setting one way or the other. This setting is global to your user account, so if you have multiple SCALGO Live instances running, the change will apply to all of those.

To ensure that it is clear what setting is used, the status will show at the bottom right of your map view at all times. It can be changed by accessing the option in the gear menu in the upper right corner of the screen.

Visibility improvements to flow lines

By popular request we have made flow lines in SCALGO Live easier to see on the map.

It is now possible to import your own raster models into SCALGO Live. The model will be available in a workspace where all the usual workspace tools and analysis options will be available. You can also choose to combine the imported model with the national model in a workspace to e.g. include the entire watershed of your imported model in that workspace.

For more information about using the raster upload feature, please consult the manual.

Today SDFE released updated hydrological corrections for the Danish elevation model from 2015, known as Denmark/2015 in SCALGO Live. These corrections, collected in 2016, significantly improve flow routing in many places and affect many of our analysis products (including the flash flood map, flow accumulation, watersheds and sea-level rise). We have updated our analysis products on the 2015 model to use the new corrections.

Workspaces

Your existing workspaces have not been updated, if you wish to update your workspace to use the new elevation model you can export all your workspace edits through your account page and then import those edits into a newly created workspace.

We are proud to announce the release of three new elevation contour data sets in SCALGO Live, all based on the 0.4m national elevation model. They are available for immediate viewing and download in SCALGO Live.

Contour map

The contour map is used to depict the main features of the elevation model with pretty and smooth contours. It is available with an equidistance of both 0,5 meter and 2,5 meter. The elevation of a contour is guaranteed to not deviate more than half the equidistance from the underlying point in the model.

Extremal points

The contour map is enriched by a set of extremal points. Those are points that are at the top of a hill or at the bottom of a depression. Each such point is annotated with the elevation value at that point.

Reference contour map

The reference contour map very accurately conveys the information of the underlying elevation model. It has an equidistance of only 25 centimeters. The deviation on reference contours in relation to DHM is not only restrained to half the equidistance (as with the contour map), but also restricted to 80 centimeters in the plane i.e. the elevation on a reference contour can be found within 80 centimeters in the model.

You can now download orthophotos as PNG and JPEG files, great for working with the photos in image editing software such as Adobe Photoshop. Note that orthophotos are high-resolution and therefore very large, if you download a large area (e.g. larger than 1 km²) you are likely to run into issues when opening it in an image editing program.

You can now create subsurface structures in workspaces. Using subsurface structures, you can simulate pipes and culverts without deforming the surface of the terrain model - thus flow on top of the subsurface structure is preserved. For more information read the announcement (in Danish).

We have added the sea-level to terrain profiles and changed the terrain profile tool such that the water level in the profile is continuously updated as the sea-level slider changes. This also works for the Flash Flood map.

Toggle between relative and absolute water depth

Relative water depths are shown on top of the terrain elevation. Absolute water depths are shown independently of the terrain.

Continuously updated point query results

Point query results are continuously updated when changing slider value.

Improved feature imports

When importing a terrain feature (by dragging a shapefile to the select tool of a Workspace), you can now choose between either using the elevation and width from an existing field on the feature or using a custom value declared in the UI.

Improved download names

Using the address data from DAWA we have improved the names of downloaded files by including a reverse geocoded name in the filename. This means that filenames will contain the name of a nearby street, city or region which makes it easier to distinguish between multiple downloaded files.

The new nationwide orthophotos from spring 2016 are now available in SCALGO Live for both visualization and download.

We have updated the elevation models and the analysis products (flash flood map, flow accumulation, watersheds and sea-level rise) to include newer buildings from GeoDanmark - acquired on August 4 2016 from Kortforsyningen. Your existing workspaces have not been changed.

We have added a number of features to SCALGO Live. Significant items in this release include:

Address search

You can now navigate to an address using the new address search bar

The source of the address data is DAWA, we have also switched to DAWA for the creation of workspace names. To facilitate this change, the SCALGO Live instance switcher has been moved. Users that have access to multiple SCALGO Live instances will find the switcher in the gear menu in the top right.

Single Sign-On Support

We have implemented support for SAML-based single sign-on (SSO). If your organization wishes to use SSO for SCALGO Live please contact support for guidance.
