Spatial Methodology

This chapter provides an introduction to spatial methodology for emissions mapping, outlining the draft framework and offering general guidance. It covers the importance of mapped emissions data, finding key spatial data sources, and understanding different spatial features. Additionally, it delves into sector-specific guidance for energy production, transportation, waste treatment, and more. Good practice tips, verification procedures, and dealing with limited data are also discussed.

Presentation Transcript

  1. Spatial Methodology Introduction Outline of draft Chapter General guidance Sector specific Highlights

  2. Chapter Introduction • What does this chapter do: • Why mapped emissions data is needed: • Reporting Spatial Emissions:

  3. Finding key spatial data sources • National Datasets: • Population and employment. • Gas distribution networks: • Agricultural data. • Road Network Information. • Airport activity data. • Local Inventory data: • Large Point Source Information. • International Datasets • Corine: • ICAO: • Eurostat:

  4. General Guidance: • Gathering and dealing with point source data • Distributing national emissions • Understanding and combining Spatial Features: • Point Sources • Area Sources (Polygons) • Area Sources (Grids) • Line Sources • Combining different spatial features • Understanding and Converting different Spatial Projections.

  5. Basic Principals • Gather Point Sources • Grid the rest • Where : • Emissionix : is the emissions attributed to a specific geographical feature (e.g. a gridcell or administrative boundary)within the spatial surrogate dataset x. • Emissiont : is the total national emission for a sector to be distributed across the national area using the (x) surrogate spatial dataset. • Valueix - jx : are the surrogate data value of each of the specific geographical features within the spatial surrogate dataset x.

  6. Good Practice • Setting priorities and work with Available Resources and data • Verification procedures

  7. Sectoral Guidance • Energy production and Stationary Combustion in Manufacturing Industries and Construction • Commercial Combustion • Residential • Agricultural & Forestry Combustion • Industrial Processes and Fugitive Emissions • Fugitive Emissions • Solvent Use • Road transport • Railways • Water transport • Air transport • Waste treatment and disposal

  8. Dealing with multiple methods
