Catchment basins #5
Comments
Excellent - need to move quickly now. |
Having a quick look now - I think we need to have a "basic" version of all examples that works without needing keys. Any extra setup is going to stop people getting started. Fancier tools requiring keys will follow in a separate section. |
So far, having some problems: I installed dodgr as follows, not sure if it is the right version: devtools::install_github("ATFutures/dodgr") I get the following errors: system.time (
+ dandenong_streets <- dodgr_streetnet (bounding_polygon, expand = 0, quiet = FALSE)

@richardbeare I think you also need the dev version of |
Ah - thought I remembered something about that, but couldn't find it. |
OK, @mpadge @SymbolixAU

A few brief comments until I find time to address the points:
I have that one firmly on my radar, just didn't have time yet to finish it off. Unless anyone else particularly wants to, I'm happy to tackle that, and will do it early next week at latest (first Dec week).
Sounds good. There's also the
No worries, all the code I did can easily just switch to keyless
Just my laziness there. I'll change that so that the script creates the local folder and data on initial run, then just uses that from then on.
My only firm plea:
If you can explain what you mean, we should be able to address it. I've checked out the OSM data for MMC at least, and the full building details are there, along with the 2 main entrance roads (emergency and public entrances). Can easily use one or the other of those, or both, or do something else with building geometry. |
I found that the OSM search for the Kingston hospital was a problem. Using the street address (as reported by google) did not give the correct location. Hopefully there's a better way. On paths - do relative paths not work robustly? I'd have thought that |
@mpadge : I've placed a rough skeleton of the catchment basin example. The plan is
It will be good if you can take over this one now. The road distance travel time estimates sound ideal for some of the work you've been doing recently. We should also clean up the geocoding for the rehab centers. I'm not sure how to do better with osm.
