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.
Example showing some point layers from the GeoDanmark "Teknik" group colored differently, with municipality boundaries in the background.

New flash flood map

Aug 17, 2016

We are excited to announce a new major upgrade to the flash flood map in SCALGO Live. The new flash flood map is simpler to use and offers several benefits:

  • You can query, download and visualize the water depth in a depression.
  • You can easily get the volume of a depression, and the water volume in the depression.
  • You can view watersheds and flow for any amount of rain.
  • More powerful watershed queries highlighting the downstream sink of the query point.

Read more about the new flash flood map here (in Danish).

Download of risk polygons

Jul 11, 2016

For certain raster-based flooding layers (e.g. sea-level rise, flooded areas of a Flash Flood Map, etc.), flood masks can now be downloaded as polygons. The polygons are simplified to greatly reduce file size and feature complexity and this makes them ready for use in GIS tools such as MapInfo, or as a basis for automated vector-based risk analysis and early-warning systems. Multiple thresholds can be specified to efficiently generate flood masks for different events, and the amount of simplification can be specified to control the complexity of the generated mask polygons.

Example of 1.34 m sea-level rise (blue area), with a downloaded (and imported) mask polygon in black on top.

Updated orthophotos

Mar 17, 2016

New nationwide orthophotos are now available on SCALGO Live for both visualization and download. The orthophotos were released by Styrelsen for Dataforsyning og Effektivisering earlier this month (release notes) and were sourced in 2015.

The new orthophoto has nationwide coverage.

Nationwide hydrology on the new DHM/2015 model now available

Mar 10, 2016

We have updated the Denmark/2015/Sea sea-level rise analysis, as well as the Denamark/2015/Rain watersheds and flow accumulation on the flooded model to have national coverage*. Previously, these layers were only available for Eastern Danmark. Interactive watershed queries using the watershed tool are also available nationwide.

For important information about hydrological corrections, please see our note.

In this area, the new model correctly resolves the stream ensuring the water takes a correct path downstream. Both partial river networks are shown here visualized on top of the DHM/2015/Rain model.

We have also added a sea-level rise computation based on the DHM/2015/Sea model.

(*) A few minor sections are not yet available due to missing data in the initial versions of the model put out by SDFE.
