Tools for Validating 'GeoJSON'
Tools for linting 'GeoJSON'. Includes tools for interacting with the online tool < http://geojsonlint.com>, the 'Javascript' library 'geojsonhint' (< https://www.npmjs.com/package/geojsonhint>), and validating against a 'GeoJSON' schema via the 'Javascript' library (< https://www.npmjs.com/package/is-my-json-valid>). Some tools work locally while others require an internet connection.
GeoJSON linters available in geojsonlint
- GeoJSON lint web service - via
geojson_lint() - GeoJSON hint JS library - via
geojson_hint()- currently usinggeojsonhintv1.2.1 - is-my-json-valid JS library - via
geojson_validate()
All three functions return the same outputs. If the GeoJSON is valid, they return TRUE.
If the GeoJSON is invalid, they return FALSE, plus reason(s) that the GeoJSON is invalid
in an attribute named errors as a data.frame. The fields in the data.frame's are not
the same across functions unfortunately, but they can be easily coerced to combine via
e.g., plyr::rbind.fill or dplyr::bind_rows or data.table::rbindlist(fill = TRUE)
The parameters for the three functions are similar, though geojson_validate() has an
extra parameter greedy that's not available in the others, and geojson_hint() has
... parameter to pass on curl options as it works with a web service.
