Part 1: Combining Geoprocessing Operations
- Open these shapefiles in today's data:
- PaCounty2015_01 (PA counties)
- DCNR_StateParks201308 (PA state parks)
- Limit_Marcellus_Poly_110317 (Marcellus shale)
and this CSV:
- Oil_Gas_Well_Historical_Production_Report
- Convert all layers to the same projection to make geoprocessing easier. Use State Plane Pennsylvania North (3650).
- Buffer the parks by two miles (10,560 feet). Use Select by location to determine how many wells are within the buffered state parks.
- Intersect counties and the Marcellus Shale layer to find the parts of counties that are in the shale.
- Dissolve the intersected layer by county name.
- Calculate the area of the dissolved features. This is the area of county within the shale.
- Join the area from the previous step to the original counties layer.
- Style the counties by the percentage of area covered by the shale.
- If you have time, use a similar process to the one above to style the counties by percentage of area within two miles of an oil or gas well.
Part 2: Model builder
- Make a model with the graphical modeler (Processing > Graphical Modeler) that:
- takes an input vector layer,
- reprojects it into 2263, and
- buffers it by 2000 feet.
- Test the model with a NYC-based dataset of your choosing.
- If you have time, add another input (for example, a number or another layer) and another algorithm to your model.
