Nohm Atlas

Explore the map.
Choose what to model.

Use Atlas to view networks, land and assets. Set the study area and choose how much detail the model needs. These screens show European examples. We plan to add data and models for other regions.

Networks and assets

View networks together.

View assets and their connections. Add network layers or change the countries shown. Check the source and date of the data.

Current Nohm Atlas methane network view across Europe, with network and provenance controls

Nohm Atlas capture. Gas topology: SciGRID_gas; 2026 capacity and system data: ENTSOG/GIE. Basemap: Esri, HERE, Garmin and OpenStreetMap contributors.

What you can examine

View networks,
land and assets.

01Networks and assets

Follow connections between generation, storage, demand and transport infrastructure.

02Land and constraints

Check a proposed site against protected areas, water and existing development.

03Geography and detail

Set the study boundary, then decide where zones are enough and where you need individual nodes.

04Model structure

Inspect the assets and flows in a model before you change a scenario.

05Other environments

The Artemis study applies the same system view to a conceptual lunar base.

Model scope

Choose the study area
and model detail.

Use the map to choose the study area and assets to include in the model.

01 / Scope and resolution

Use more detail in the study area.

Model one country, region or network at node level and keep surrounding areas less detailed.

Expand the study area

Include neighbouring areas when flows or constraints cross the boundary.

Group regions

Group similar regions before setting the model detail.

Example: node level in the study area, less detail farther away.

02 / Model composition

Adapt an existing model to a new study.

Use the part of a larger model that the study needs. You can extend the study area or add another resource, such as water. Keep the original model for comparison.

Reuse model components

Adapt an existing model instead of rebuilding every component.

Compare versions

Keep the original and updated scenarios for comparison.

Ways to adapt

Extract

Extend

Connect

Compare
scenarios

Keep both model versions for comparison.

03 / In development

Run the model from Atlas.

We are developing a way to prepare and run models from Atlas. Results would appear on the map.

Each run would record its scenario, climate year and model version.

Running models from Atlas is planned and is not shown in the current demo.

Use the platform to analyse the data and run models.
