Three Rivers Park District Theodore Wirth Request

[ravenmcknight]

Description

This PR creates a new folder, follow_up_requests, with one completed request for Three Rivers Park District. The script follow_up_requests/trpd-wirth-home-locations/theodore_wirth_agency_percentages.R aggregates estimated home locations for visitors to Theodore Wirth Regional Park into several regions of interest, such implementing agency boundaries, suburban Hennepin County, etc. The results are written to an excel workbook with a metadata sheet in the same folder.

Hi @eroten! I think this one is pretty straightforward.

One thing to note is that I read the implementing agency boundaries from a shapefile on the N drive (line 58) because I can’t currently connect to GISLibrary through R (issue with my machine, working to get it fixed with IS). Please feel free to change that if you’d rather this use the councilR function to access GISLibrary.

Thanks again for getting this started!

@ravenmcknight Do you recall how the agency boundaries were created? I'd prefer we have that instead of a full path

[ravenmcknight]

@eroten The agency boundaries should be the equivalent of reading the “RegionalParksSystemImplementingAgencies” layer from GISLibrary. I’m just now realizing that this is the only data across the whole repo that would not be accessible to someone outside of the Council, though. Would it make sense to save a copy to data-raw and read it from there? I couldn’t find the agency boundaries on Geospatial Commons or anywhere else public, so I’m not sure about “publishing” it here.

@ravenmcknight, thats a good point. Could we replicate the data manually using the city boundaries and county boundaries? We should be able to use an st_difference() to cut out MPRB and Bloomington from Hennepin County and St. Paul from Ramsey County. That can be done entirely with data from {tigris}, so will be reproducible outside the Council. We would save the code to make the dataset, but not have to save the dataset itself.

@eroten ah yes, I like that! I can put that together a little later today.
