[![AppVeyor build status](https://ci.appveyor.com/api/projects/status/github/mdsumner/howzat?branch=master&svg=true)](https://ci.appveyor.com/project/mdsumner/howzat)

[![Codecov test coverage](https://codecov.io/gh/mdsumner/howzat/branch/master/graph/badge.svg)](https://codecov.io/gh/mdsumner/howzat?branch=master)

The goal of howzat is to convert spatial objects to [WKT (Well-Known-Text) geometry format](https://en.wikipedia.org/wiki/Well-known_text_representation_of_geometry). 

WIP: supremely unuseable and untested for now. 

## Installation

You can install the  development version from [GitHub](https://github.com/) with:

``` r

# install.packages("devtools")

devtools::install_github("mdsumner/howzat")

```

## Example

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

```{r example}

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)

```
