geojsonsf

[SymbolixAU]

In the readme you identify the conversion to/from GeoJSON is slow

They are slower with the Spatial classes due to internal conversion to/from json

Other than the date fix (thanks again!), is there anything you would like added to geojsonsf so you can use it in rmapshaper to do the GeoJSON <--> sf conversion?

Working in geojsonsf branch.

To Do:

• remove support for geojson lists
• drop geojsonio (possibly to Suggests for now as it's useful in tests)
• figure out what classes to support. geojsonio creates c("geojson", "geoj_json", "json") and geojsonsf creates c("geojson", "json")
• Wait for geojson_sf with NA numeric values changes to character SymbolixAU/geojsonsf#79 to be fixed
• drop geojsonlint (use jsonify::validate_json to validate character strings of geojson)
• drop support for POSIXlt (or convert on the fly)

Would you like me to add a json class` to geojsonsf ?

[ateucher]

Sorry @dcooley I was wrong - geojsonsf already adds json class:

library(sf)
#> Linking to GEOS 3.8.1, GDAL 2.4.4, PROJ 7.0.0
library(geojsonsf)

xs <- st_polygon(list(cbind(approx(c(0, 0, 1, 1, 0))$y,
                            approx(c(0, 1, 1, 0, 0))$y)))
xsf <- st_sf(geometry = st_sfc(xs, xs + 2, xs + 3), a = 1:3)

class(geojsonsf::sf_geojson(xsf))
#> [1] "geojson" "json"

Checklist updated - rmapshaper can just have methods for geojson I think...
