var csv2geojson = require('csv2geojson');
var geoJson = csv2geojson.csv2geojson(csvString, function(err, data) {
// err has any parsing errors
// data is the data.

Parse a CSV file and derive a GeoJSON
FeatureCollection
object from it. Err is non-falsy if latitude and longitude values cannot be
detected or if there are invalid rows in the file. Delimiter can be ','
for CSV or '\t' for TSV or '|' and other delimiters.
Delimiter can also be auto
, and it will try , \t | ;
and choose the 'best'.
csv2geojson.dsv(delimiter).parse(dsvString);
The dsv library for barebones DSV parsing.
csv2geojson.auto(dsvString);
Automatically choose a delimiter to parse a dsv string with, and do it.
csv2geojson.toPolygon(gj);
csv2geojson.toLine(gj);
Given a GeoJSON file consisting of points, derive one consisting of a polygon or line that has the coordinates of those points, in the order given.
