Leverage sf?

[cpsievert]

cc @sckott @rmendels

The fairly new sf package is gaining lots of traction and there is even a new geom_sf() coming to ggplot2

Assuming we can represent griddap/tabledap data structures using simple features, we can leverage/augment some already existing "automatic plotting methods" (e.g., plot.sf() and geom_sf()).

I'm thinking that (over the next week or so) I will attempt to write some tabledap/griddap_csv/griddap_nc methods for the sf::st_as_sf() generic, so generating plots could be as simple as:

library(rerddap)
library(sf)
library(ggplot2)

d <- st_as_sf(tabledap('erdCinpKfmBT'))
plot(d)
ggplot() + geom_sf(data = d)

Does this sound reasonable?

[rmendels]

It sounds interesting, I want to look at the quality of the plots, but just that type of simplicity is what I am after.

@rmendels fyi this has a decent overview of plotting sf objects via the plot() generic -- http://r-spatial.org/r/2017/01/12/newssf.html

To see some geom_sf() examples:

devtools::install_github("tidyverse/ggplot2#1990")
library(ggplot2)
?geom_sf # see examples section

[rmendels]

Neat. But can it handle rasters say over the ocean, or over land as in my examples, or are you thinking of only using this for table data? And I have no problem if you build against a feature of ggplot2 that is still only on github.

can I close this @cpsievert ?

yep
