SCALGO Live's depression map allows you to investigate the depressions in the terrain and has just become much more powerful. You can now use new volume and area sliders to hide small depressions and focus on the bigger ones. Furthermore, the default rendering style has been changed to a hatched pattern that makes it easier to distinguish between inside and outside of a depression.

But that's not all, several other interesting features have been added to the depression map:

• On point queries you now get the area of the maximal depression and the area of the selected region as well.
• You can download the map as both an area and volume raster, and as depression polygons annotated with area and volume.
• The profile tool now shows depressions too.
• A banded rendering style is now supported - more on that below. You can use either volume or area to define the bands.
  
• We now support volume and area contours, allowing you to easily find areas in a depression with a particular capacity.
  

Some of these features are shown here:

Banded styles for all analyses

We now support banded rendering styles for all analysis layers. Banded rendering allows you to color the analysis layers in three color bands defined by two threshold values on water depth or event. Previously this was possible only for the flash flood map. Furthermore we have tweaked the colour palette to get a nicer looking output. We have also created a colorful slider to help you set the right threshold values.

With SCALGO Live modelspaces you can now import your hydrodynamic models into SCALGO Live where the simulation results come to life through advanced visualisation, interactive exploration and easy sharing with colleagues, clients and consultants.

You can read more about Modelspaces on the add-on page or get the details in the documentation.

We have made new learning material that demonstrates how you can approach different projects based on concrete use cases. These new use-case videos cover a wide range of topics and demonstrate how the tools in SCALGO Live can be used for different purposes. The videos will give you inspiration about out what projects are possible with SCALGO Live, and provide you with guidance on how to carry them out.

Just getting started with SCALGO Live? We also have a number of getting started videos that can help you with the basics.

Links to the use case and getting started videos are available from the Help menu inside SCALGO Live.

By popular demand we have made some of the Environment Agency flood risk assessment maps and flood zone maps for England available directly in SCALGO Live.

Flood maps for planning

From the flood maps for planning service we have added the following layers:

• Areas benefiting from flood defence
• Flood defence
• Flood storage area
• Flood zone 2
• Flood zone 3
• Main rivers

Flood warning information service

From the flood warning information service we have added depth and speed layers for the low, medium and high risk rainfall scenarios corresponding to return periods of 30, 100 and 1000 years. To make this easily accessible inside SCALGO Live we have created a slider that allows you to quickly navigate between the return periods. We have also given you filters on water depth and velocity so you can focus on areas with a certain minimum water depth or velocity.

All the new layers are available from the library.

We have improved our system for exporting SCALGO Live maps to images as JPG and georeferenced PDFs. The new system is significantly faster than the old system and does a better job at determining an appropriate size for dialogs in the output, including the legend. By popular demand, we now also include vector data that you have dragged into SCALGO Live for visualisation in the exported document.

Try it out and don't hesitate to let us know what you think.

A year back we asked ourselves: "What is the simplest and most intuitive way to shape the terrain and test how landscaping ideas influence the flow of surface water?". Since then we have worked hard, and today we release a brand new set of tools. Check it out in SCALGO Live, and let us know what you think.

Interested in learning more? You can sign up for our next webinar where we will demonstrate the tools in detail. The webinar is available in English and in Danish.

The default coloring of flooded areas is now based on water depth, such that shallow areas are light blue and deep areas are dark blue, instead of the event based coloring that has been the traditional default choice in SCALGO Live. This makes the maps more intuitive and problematic areas easier to distinguish. The event based coloring is still available in the layer settings . In parallel we are also rolling out support for depth filtering in the sea-level rise analysis. This happens on a country-by-country basis.

Today we announce the availability of a nationwide high-resolution mapping of impervious surfaces for SCALGO Live in Denmark. The map, produced by SCALGO, is based on machine learning techniques and has a resolution of 20cm. It is available as a standalone layer in the Imperviousness category in the library. In Danish the category is called Befæstelseskort.

The mapping of impervious surfaces segments the country into 3 different classes: pervious, impervious and lake. The category is further subdivided into a building type and a general other impervious category.

Watershed queries

When you perform a watershed query you get the total area of impervious surfaces in the watershed.

Annotated administrative regions

We have annotated a number of datasets, including the cadastral parcels, sewer catchments, planning zones as well as municipal regions with information about imperviousness. You can find those layers in the Imperviousness category alongside the impervious surfaces map itself. For each polygon in those data sets we have added a field that provides the total impervious area in the polygon, as well as the percentage of impervious surfaces.

We now give local users (e.g. municipalities and water utilities) access to the full national SCALGO Live setup in their country.

As a consequence, workspaces and links can now be shared freely between consulting engineers and local users. See the manual for more info on how to share workspaces.

Note that if you previously had access to a local theme to facilitate sharing (e.g., you are an engineer working for a municipality), this access will be revoked as it is now unnecessary and the local themes will be retired.

Special notice for WMTS users

If you use SCALGO Live WMTS services in external GIS software you will have to update your service URLs. You can fetch a fresh WMTS link in the ticket configuration page. No other changes are necessary. If you do not have easy access to change your WMTS settings and need a little time in which the old system is still available, please contact SCALGO Live support.

We have made some updates to the way you download data and analysis results from SCALGO Live. Most notably, we have moved the file format and projection controls to the menu that appears after you have selected the layer you want to download, and we only show options relevant for the particular layer. This makes downloading easier if those details are not important to you. The update also includes new download features.

New features

We have also added new download options.

Lower resolution elevation model downloads

For many workflows external to SCALGO Live, the normal high-resolution elevation model available nationwide in SCALGO Live is too big to handle. You can now choose a resolution when you download, and the layer will be down-sampled to this resolution.

Download water depth for a particular sea-level rise event

Need to know exactly how high the water column on a cell is for a sea-level rise of e.g. 2 meters? You can now download a water depth raster for a particular sea-level rise.

Updates to the Danish elevation model

Since the Danish elevation model is partially updated every year, it is often important to understand when the data for a particular area was collected. To that end, we have added a layer, based on data from SDFE, showing the composition of the Danish elevation model (DHM). You can use the point query tool on this layer to get more information about the acquisition time for a particular area. The layer is available in the Elevation category in the library.

Alongside this change we have renamed the Danish analyses layers to simply "Denmark" to underline the fact that it does not make sense to attribute a single year to the model. As always, we will continue to update our analyses as the model evolves, to ensure you are always looking at the newest data.
