Sources of Methane Emissions (Vista-LA), South Coast Air Basin, California, USA

Documentation Revision Date: 2018-01-03

Data Set Version: 1

Summary

This data set provides spatial data products with identified and classified locations of potential methane (CH4) emitting facilities and infrastructure in the South Coast Air Basin (SoCAB). These data products form a GIS-based mapping database designed to address shortcomings in current urban CH4 source inventories and is known as Vista Los Angeles (Vista-LA). SoCAB is the air shed for the greater Los Angeles urban area, which includes urbanized portions of the Los Angeles, Orange, Riverside, and San Bernardino Counties, California, USA. Vista-LA consists of detailed spatial maps for facilities and infrastructure in the SoCAB that are known or expected sources of CH4 emissions and illustrates the spatial distribution of potential CH4 sources, representing a first step towards developing an urban-scale CH4 emissions gridded inventory for the SoCAB. Vista-LA spatial data sets were created utilizing an assortment of publicly available data sources from local, state, and federal agencies for the years 2012 to 2017. The final Vista-LA database contains over 33,000 entries, which are presented as thirteen CH4 emitting infrastructure maps.

This data set includes 13 compressed shapefiles (*.zip). The shapefile data are also provided in .kmz format for viewing in Google Earth.

Data Set Overview

The Vista-LA database is a GIS-based CH4 emissions mapping database designed to address shortcomings in current urban CH4 inventories. Vista encompasses key CH4 emissions categories from the Intergovernmental Panel on Climate Change (IPCC) greenhouse gas (GHG) inventory methodology. Vista-LA spatial data identify and classify locations of potential methane emitting facilities and infrastructure in the South Coast Air Basin (SoCAB). SoCAB is the air shed for the greater Los Angeles urban extent, which includes urbanized portions of the Los Angeles, Orange, Riverside, and San Bernardino Counties. Vista-LA spatial data were created utilizing an assortment of publicly available data sources from local, state, and federal agencies. Vista-LA spatial data are organized using the IPCC categorization for greenhouse gas emissions. IPCC categories utilize a level system (levels 1 to 3), with level 1 relating to general categories (“CH4 Sectors”) and level 3 relating to specific emission sources (“CH4 Sources”). This database contains over 33,000 entries which are presented as CH4 emitting infrastructure maps that will improve understanding of CH4 emissions in the Los Angeles megacity.

Data File Information:

The Vista-LA data set features thirteen spatial layers totaling to 33,614 individual features comprised of geo-located and validated points, polylines, and polygons. This data set contains 13 compressed shapefiles (.zip) of which three are point layers, one is a polyline layer, and nine are polygon layers. The spatial domain for all the data has been geo-processed to fit the SoCAB extent and all data are georeferenced to the WGS 1984 Datum and UTM Zone 11N Projection. Units for dimensions and activity data has been kept consistent with the original data source.

Companion Files: 13 .kmz files are provided which contain the shapefile data for viewing in Google Earth along with NACP_Vista_LA_Data_Information.pdf  that provides specific information and definitions for every data field found in each Vista-LA spatial layer

Application and Derivation

The Vista-LA data product is a key tool for CH4 emissions research and mitigation efforts; by (1) mapping areas of CH4 emitting infrastructure, (2) identifying targets for CH4 surveys, and (3) enabling interpretation of atmospheric observations, including source attribution, and comparison of measured emissions to permitted or reported emissions. Combined with atmospheric observations, Vista enables systematic study of urban CH4 emission sources.

Quality Assessment

Vista-LA data have been significantly geoprocessed, edited, digitized, and standardized on the ArcGIS 10.4 platform. Point source locations and spatial extents of infrastructure known or expected to emit methane were extensively validated by comparing multiple data sets which had varying degrees of spatial accuracy. The uncertainty in the final data has been reduced relative to the original data through comparisons of the existing publicly available data and more recent aerial imagery. Where applicable, the point source locations or spatial extents were modified using the best available information, which significantly reduced the uncertainty in the locations of individual facilities and/or infrastructure.

Data Acquisition, Materials, and Methods

The Vista-LA database extends over SoCAB, the air-shed for the greater Los Angeles urban extent, including the urbanized parts of Los Angeles, Orange, Riverside, and San Bernardino Counties. It follows the IPCC CH4 emissions reporting framework (IPCC, 2006) and is compatible with the State of California CH4 emissions reporting. The database comprises of infrastructures associated with emissions from primarily three sources: energy; agriculture, forestry and other land use; and waste. Spatial data on these infrastructures were compiled from reliable and verified public databases on government and federal/state research agency portals. For more information refer to Carranza et al 2017.

Data Access

These data are available through the Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC).
