write new content for interactive plotting with leaflet

[ErinBecker]

Leah has a sample lesson that she can provide to show one possible way of implementing this.

@lwasser - could you please put the link to the sample lesson in this issue?

[lwasser]

Here you go

https://earthdatascience.org/courses/earth-analytics/get-data-using-apis/leaflet-r/

i think i may have another one somewhere but this is a start.

adding @tyson-swetnam to this conversation! @ErinBecker why can't i add him as an assignee since he is working on the lesson? just curious. it's nice if people see someone is working on htis actively

[ErinBecker]

@tyson-swetnam hasn't accepted the invite to join the geospatial-maintainers team yet, and so he can't be assigned issues. I've emailed him just now to remind him about the invite. Should be able to start assigning him work soon!!

[lwasser]

ok wonderful. i was wondering what that is about!! thanks @ErinBecker he is working on this lesson which is super awesome!!

[tyson-swetnam]

Sorry @ErinBecker somehow I missed seeing the invite in my Github. I'm here now!

[tyson-swetnam]

@ErinBecker Plotting with Leaflet instead of plot() could impact the entire rastor/vector lesson structure. It would be less work to just introduce Leaflet as a new Lesson (15). On the other hand, if we integrated it as a major revision to the lessons starting with Lesson 2 (Plotting Rasters) and Lesson 6 (Opening Shapefiles in R) it could eventually make its way into all of the lessons.

Thoughts?

Here are the rstudio leaflet lessons: https://rstudio.github.io/leaflet/

[lwasser]

we are not replacing plotting throughout @tyson-swetnam we are adding a new lesson on interactive plotting :)

[lwasser]

in a separate issue we are replacing plot() wtih ggplot () throughout. that is static plotting.

[lwasser]

@ErinBecker i'm wondering if we need to write very explicit issues that explain a bit of what we are trying to do with each new set of edits and what was discussed in the meetings? otherwise i think everyone may get confused :) and rightfully so as they weren't at all of the discussions which makes some tasks confusing but it's a nice way to save everyone's time!!

[ErinBecker]

@lwasser - I agree. It would be good to write up more detailed issues. I assumed that the meeting minutes were sufficient background, but I probably have some blind spot there since I was at the meetings!

[ErinBecker]

@lwasser - I've got back to back meetings starting soon. Would you be able to write some more detailed issues for the Maintainers so they know what the next steps are?

[lwasser]

I can work on this a bit tomorrow or maybe tonight! I’m in the same camp tho – meetings this afternoon and a presentation. ☺

[ErinBecker]

I'll see what I can do!

[ErinBecker]

Thanks @tyson-swetnam and @lwasser for the conversation above. I'm elaborating a bit on the CAC discussion to see if I can help clarify the goals here.

The CAC had an in-depth discussion about the various options for both static and interactive plotting of geospatial data. The options that were considered for interactive plotting were leaflet and mapview. The relative benefits and downsides of these two packages were considered and the majority voted to use leaflet, as it is easier for learners to customize.

There is more detail about the CAC's discussions of these issues

here here and here

The decision at this point was to add a new episode to the raster-vector lesson for interactive plotting using leaflet, doing some customization but keeping the leaflet code as simple as possible.

[ErinBecker]

This won't be implemented before the first lesson release, currently scheduled for mid-July. I've added a status:wait label.

[rbavery]

Hi @ErinBecker just curious what the status of this is? I'll be teaching some geospatial R plotting and since most time is spent doing interactive analysis rather than publication quality static graphics I'd prefer to show folks first how to use mapview. If there's something already in the works for interactive mapping in R I would love to work off of that, if not no worries.

[kerchner]

We used this material before, and it worked well. Took about an hour:

I think the main issue here is that many learners would like to walk away knowing how to create a choropleth map, whether it's interactive, like with leaflet, or static. Leaflet is great, by the way, but it might be one step beyond simpler cholopleth mapping, in terms of a logical order of instruction.

I favor mapview for it's simplicity so my strategy during workshops is to continually encourage learners to view their output using mapview. My preference would be to include a tooltip pointing learners to mapview and reminder for instructors in the notes rather than writing standalone interactive plotting content.
