New in Modelspaces: Explore hydrodynamic simulations and visualise the dynamics of flow velocity

May 13, 2024

We have just released some exciting features for Modelspaces in SCALGO Live.  You can now query information about water flow, volume, and depth from your dynamic flood simulations.

We have also created a whole new set of visualisation styles to animate the dynamics of velocity.  The old styles are still available, should you need them.

Please read more in the accompanying blog post.

One of the new features allows you to draw a line across flux results to get information about flow rate and volumes.

National German high-resolution land cover map

May 6, 2024

Today we announce the availability of a nationwide high-resolution land cover map for SCALGO Live in Germany. The map, produced by SCALGO, is based on machine learning techniques and has a high resolution of 20 cm.

It is available as a standalone layer in the Land cover category in the library.

The map is fully integrated into SCALGO Live Germany and is, for instance, used to show aggregate land cover information for watershed queries. For more information please see the complete release announcement.

German cadastral maps

As part of this release we are also adding aggregated cadastral data to SCALGO Live Germany. The new layer, called Flurstücke, is available in the ALKIS category. We have also computed aggregated land cover information for each land parcel, you will find this layer in the Land Cover category.

Note that only a select number of federal states are available in the Flurstücke layer, please consult the documentation for more information about this.

Specify basins and protrusions by drawing their outer boundary

Mar 12, 2024

SCALGO Live has long supported creating basins and protrusions having side slopes with a given gradient.   The way this works is that you draw a polygon covering the bottom of your basin or the top of your protrusion (hill).  Then you specify a gradient, and SCALGO Live automatically interpolates between the drawn flat area and the surrounding terrain while respecting the specified gradient.

A basin created by drawing the bottom area and adding slopes on the outside.

There are use cases, however, where it is more natural to be able to specify the outer boundary of your basin or hill.   For example, you may have a given plot of land where you want to create water storage.

SCALGO Live now supports this use case:    Again you draw a polygon and specify a gradient, but this time SCALGO Live adds the slope on the inside.

A basin created by drawing the outer boundary and adding slopes on the inside.

The tools you have always used for creating basins and protrusions now support both ways of specifying side slopes.  Use the checkbox "Side slopes are outside" if you want to add slopes on the outside of your area (the default is now to add them on the inside).

The new controls for specifying if side slopes go on the inside or on the outside of the drawn area.

The two modes behave a bit differently:

  • When adding outside slopes, the polygon you draw is a flat horizontal polygon (since it's the bottom of your basin), so in the profile view you will see all vertices at the same elevation (and you cannot change this).   How far the side slopes will go depends on the elevation of the terrain, for an uneven terrain it is not easily predictable.
  • When adding inside slopes, the polygon you draw actually has 3D coordinates (SCALGO Live automatically samples the terrain at each vertex).   This makes it possible to create a basin whose outside aligns with the terrain along the given area boundary.   From these 3D coordinates, SCALGO Live then computes the appropriate sloping to achieve the target depth (or height for protrusions).    The depth is always measured from the lowest boundary vertex, the height is measured from the highest boundary vertex.

    When you edit the boundary of such a basin, you may have to readjust the elevations at the vertices to make sure it again aligns with the terrain, otherwise you'll have sharp edges on the boundary.

Simplified path features

Feb 28, 2024

Since the very beginnings of SCALGO Live, it was possible to modify the terrain model to see how this influences the flow of water and the various analyses.

The first tools were quite simple, and allowed you to draw walls, depressions, or protrusions with vertical walls only. Then came side slopes for more realistic dams and basins, the possibility to specify the cross section (for instance to represent a river bed according to actual measurements), and most recently the ability to create a terrain by drawing contour lines.

Until now, when you draw a path feature using the "interpolate", "raise", or "raise flat" tools without any side slopes, it was still represented in the terrain as we implemented it in the first version many years ago (top figure below).

We have now changed it so that when you create a simple path without side slopes or general cross sections, it is added to the terrain using the same method that we use for general paths (that is, for paths with side slopes or cross sections). As you can see in the bottom figure, this avoids the traditional plateaus at each vertex, and in general fits better with the other ways of using our tools.

(top) Old path style with rounded edges and discontinuities at joints. (bottom) New default path style.

It is worth noting that the new method is applied only to newly created features - your existing features remain unchanged. If you want an existing path feature to use the new method, use "Edit both cross sections" from the context menu, select "Width only", and save again. Note that you will not be able to go back to the traditional way, though.

New land cover map for Finland

Apr 26, 2023

We are happy to announce that SCALGO Live in Finland has been updated with a new land cover map covering the entire country. The land cover map is produced using a machine learning model developed by SCALGO, in close collaboration with SYKE (The Finnish Environment Institute).

Figure 1. The new land cover map divides Finland into 10 land cover classes.

The new map is based on a powerful machine learning model that allows us to classify each pixel into the following categories: impervious, shallow vegetation, dense vegetation and bare land. These four land cover classes are supplemented with auxiliary data from DigiRoad and Maastotietokanta, to create a map with 10 unique classes.

The map is fully integrated into SCALGO Live and is, for instance, used to show aggregate land cover information for watershed queries. For more information please read the accompanying blog post.
