csv2geojson.csv2geojson(csvString,{latfield:'LATFIELDNAME',lonfield:'LONFIELDNAME',delimiter:','},function(err,data){});
Parse a CSV file and derive aGeoJSONFeatureCollectionobject from it. Err is non-falsy if latitude and longitude values cannot bedetected 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 beauto, and it will try, \t | ; and choose the 'best'.
csv2geojson.dsv(delimiter).parse(dsvString);
Thedsv 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 polygonor line that has the coordinates of those points, in the order given.
The latest build will be at
https://npmcdn.com/csv2geojson@latest/csv2geojson.jsOpen that path in a browser to be redirected to the lastest pinned version.
Looks for fields like/^Lat/i.
- topojson supports joining data in CSV
- gdal supports specific CSV structures to and from other data formats
This is what powers the CSV/TSV import ofgeojson.io.
