howzat

The goal of howzat is to convert spatial objects to WKT (Well-Known-Text) geometry format.

WIP: supremely unuseable and untested for now.

Installation

You can install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("mdsumner/howzat")

Example

This is a basic example which shows you how to solve a common problem:

library(howzat)


library(silicate)  ## just for data examples
library(sf)        ## just to verify the formatting

wkt(sfzoo$polygon)
wkt(sfzoo$polygon) == st_as_text(sfzoo$polygon)
wkt(st_sfc(sfzoo$multipolygon, sfzoo$multipolygon + 10))
wkt(st_sf(a = 1, g = st_sfc(sfzoo$multipolygon)))
wkt(sfzoo$multilinestring)
wkt(sfzoo$multilinestring) == st_as_text(sfzoo$multilinestring)
wkt(sfzoo$linestring)
wkt(sfzoo$linestring) == st_as_text(sfzoo$linestring)
wkt(sfzoo$multipoint)
wkt(sfzoo$multipoint) == st_as_text(sfzoo$multipoint)
wkt(sfzoo$point)
wkt(sfzoo$point) == st_as_text(sfzoo$point)


wkt(sfzoo$multipolygon)
wkt(sfzoo$multipolygon) == st_as_text(sfzoo$multipolygon)
