Source-Sink Matching
1. Minimize distance from source to sink2. Minimize distance to CO2 pipelines, if possible3. Avoid sensitive areas
– Protected aquifers– State & national parks– High density population areas

Goals
1. Create unique maps for qualitative source-sink matching
2. Use some spatial analysis to tease out prospective source-sink matches

1) Merge protected areas
![Page 18: Systematic approach to source-sink matching for geological carbon capture and sequestration](https://reader036.vdocument.in/reader036/viewer/2022081604/5681606e550346895dcf9508/html5/thumbnails/18.jpg)
2) Select sources & sinks within 10 km of protected areas
![Page 19: Systematic approach to source-sink matching for geological carbon capture and sequestration](https://reader036.vdocument.in/reader036/viewer/2022081604/5681606e550346895dcf9508/html5/thumbnails/19.jpg)

What’s Next?Create a population density map…
…And use it to screen for Sources & Sinks
![Page 25: Systematic approach to source-sink matching for geological carbon capture and sequestration](https://reader036.vdocument.in/reader036/viewer/2022081604/5681606e550346895dcf9508/html5/thumbnails/25.jpg)
Steps:
1. Download block shapefiles with population and housing unit counts in them http://www.census.gov/geo/www/tiger/tgrshp2010/pophu.html
Population count in each housing unit
These polygons describe housing units

3) Consolidate data
HUGE data set:914,231 polygons!
![Page 27: Systematic approach to source-sink matching for geological carbon capture and sequestration](https://reader036.vdocument.in/reader036/viewer/2022081604/5681606e550346895dcf9508/html5/thumbnails/27.jpg)
2) Calculate areas of blocks
![Page 28: Systematic approach to source-sink matching for geological carbon capture and sequestration](https://reader036.vdocument.in/reader036/viewer/2022081604/5681606e550346895dcf9508/html5/thumbnails/28.jpg)
3) Using “Field Calculator” in Attribute Table, calculate population density
4) Export the population density data to a new feature class and map it!
