Released maps

Maps of Energy Nexus are published here once their data rights are cleared and they have been reviewed. Each shows its time and space reference, its sources and its uncertainty.

05Process

How the process runs.

Process

Released maps: Layers to published map

Layers enter with their rights, are aligned, analysed and checked for uncertainty, then released after public-safe review; a map is a governed spatial claim.

  1. 01 Data

    1. 01Source layers with their rightsDataset · NXS-GRX (canonical data, provenance and risk)Spatial views of The Global Risks Index (NXS-GRX) products sit under the boundary licence gate. Rights classification sets how a layer may be used.
  2. 02 Harmonise

    1. 02Coordinate reference and boundary versionRecord · NXS-EOP (earth observation and digital twins)The area of interest preserves its coordinate reference system, polygon validity and observation support. Boundary versions are kept.
    2. 03Harmonise units, variables and timeStepUnit metadata, conversion records and transformation logs are required. Alignment is an evidence event, not hidden preprocessing.
  3. 03 Analyse and check

    1. 04Analyse with a recorded processing recipeModel · GIS teamA processing recipe records parameters, calibration, inputs and output lineage. The analysis methods are named in each product’s own record.
    2. 05Spatial uncertainty checkGateSpatial uncertainty is recorded and affects downstream use. A high-uncertainty polygon may suit internal review, not public-safe release.
  4. 04 Publish

    1. 06Spatial metadata bundleRecordThe bundle records boundary type, jurisdiction, geometry version, projection, resolution, source, time window, uncertainty and access class.
    2. 07Public-safe release of the mapDecisionThe output record names the redactions, uncertainty and public-safe reviewer. A map is a governed spatial claim, never merely a picture.

Spatio-temporal intelligence · Data protocols: semantic, jurisdictional and temporal intelligence · NXS-EOPDesigned programme process, not a record of operation. No cycle has run and every programme is at service level R0. A gate is a programme decision, never a public-authority approval, certification or deployment authorisation. The pages cited are design doctrine.

06Reading the maps

Cautions that apply to energy maps.

  • Open grid maps (for example from OpenStreetMap) are incomplete at distribution level.
  • Capacity maps do not show availability; derating in heat and drought matters.
  • Locations of critical substations are released only at owner-agreed aggregation.
  • Generation-mix maps are annual averages and hide seasonal and hourly scarcity.
07Status

Releases appear as they are reviewed.

Analysis runs in Foundry; reviewed releases are listed here.
