Table of Contents


By pressing the layers_button Button a sidebar with different kind of layers is shown at the left of your screen.


Each layer has a set of tools as shown below


  1. Shows the symbology section of the layer (legend)
  2. Shows the information section (primary a link to the GitLab repository, it is highly recommended to look for more information about the data in the GitLab Repository )
  3. Download the default dataset
  4. Download layer for the layer selection

There are two categories of layers:

  1. Vector Layers
  2. Raster Layers

The following layers can be found and visualized (you can see also the legend and also the information section of each layer):

Raster Layers

Following raster layers are visualized:

  1. 17 x Buildings layers:

    • Heat Density Map (total / residential / non residential)
    • Cooling Density Map (total / residential / non residential)

    • Buildings Volumes (total / residential / non residential)
  2. 1 x Population layer

    • Population Total
  3. 3 x Renewable Energy Sources Potential layers:

    • Solar radiation on building footprint
    • Wind potential at 50m
    • Forest Residues
  4. 5 x Climate layers:

    • Temperature
    • Cooling Degree Days
    • Heating Degree Days
    • Solar Radiation
    • Wind Speed

Vector Layers

The following vector layers are visualized:

  1. 4x Industry layers:

    • Industrial Site Emission
    • Industrial Site Excess Heat
    • Industrial Site Company Name
    • Industrial Site Subsector
  2. 6 x Renewable Energy Sources Potential layers:

    • Waste Water Treatment Plants Power
    • Waste Water Treatment Plants Capacity
    • Agricultural Residues
    • Livestock Effluents
    • Geothermal Potential Heat Conductivity
    • Municipal Solid Waste
  3. 1 x Electricity Layer:

    • Electricity CO2 Emissions Country Average

Calculation Module Layers

Some Calculation Modules generate a layer with the calculated results, such as CM - Scale Heat and Cool Density Maps for instance. When these CMs are run, the relative layer appears on the left side of the screen, in the layer section, at the very bottom. The layer can be then selected and used in further calculations. As for every other layer, few buttons below the layer title allow showing the layer symbology, available information about the layer, downloading the layer dataset, and downloading the layer as a raster file.
