New Hydrological Corrections

May 2, 2017

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.

The bridge over the the Gudenå along the new freeway in Silkeborg is opened by a hydrological correction. The blue line shows the updated flow accumulation analysis.
The bridge was not represented in the old set of corrections, causing a significant detour of the Gudenå.

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.

Elevation contours now available

Mar 31, 2017

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.

Download orthophotos as JPEG and PNG

Mar 27, 2017

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.

Select the download format from the "Aerial Format" dropdown menu.

Subsurface structures in workspace

Mar 17, 2017

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).

Sea-levels in terrain profiles

Dec 16, 2016

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.

Updated orthophotos

Nov 15, 2016

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

Models and analysis update

Nov 4, 2016

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.

User interface updates

Oct 21, 2016

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.

User interface updates

Sep 28, 2016

We have added a number of features to SCALGO Live, fulfilling a number of popular feature requests:

Profile exports

You can now export profiles as CSV files, making it easier to import and graph the data in third-party tools. The export is initiated by hitting the green download icon in the profile window.

Moving features

You can now move entire workspace features at a time. To move a feature, use the select tool to select a feature, then press and hold the shift button while dragging the feature with the left mouse button to move it. To move polygons you can also place the mouse cursor in the interior of the polygon and drag the polygon with the left mouse button to move it.

Login improvements

You no longer stay on SCALGO Live Global upon logging in, instead you are automatically transferred to your Live Flood Risk page. Furthermore, workspaces are now folded by default (unless you're following a link displaying a layer from a workspace, in which case that particular workspace is unfolded).

GeoDanmark/FOT data, Matrikelkortet now available

Sep 6, 2016

The Danish Agency for Data Supply and Efficiency (SDFE) regularly releases extracts of a number of topographic and administrative geodata products including polygons representing the boundaries of the administrative subdivisions in Denmark (DAGI), topographic base data with road, railroad, and stream geometries, buildings, and much more (GeoDanmark/FOT), as well as Denmark's digital cadastral map (Matrikelkortet). From now on these datasets are fully accessible in SCALGO Live, including fast download of local extracts. The datasets will be updated regularly in the future. Along with this release the following changes have been made:

  • The "Administrative Borders" category is renamed to "DAGI".
  • All layers from the "Vector Subdivision" category can now be found in the "GeoDanmark" category.
  • The "DHyM Tilpasninger" layer is replaced by two layers in the new "Hydrological Corrections" category: "Denmark/Rain" and "Denmark/Searise", representing the set of hydrological corrections based on the old national Danish elevation model DHM/2007.
  • We have enhanced the display options. For example, the items in a GeoDanmark vector layer can be colored differently by their "FOT ID" to easily distinguish different objects, or uniformly in yellow, green, purple or blue to distinguish different layers. Polygonal data can be displayed with their outline only, so other data can be seen in the background.
