GeoWKTer is a JavaScript library designed to convert Well-Known Text (WKT) representations of geometries into GeoJSON format. This tool is useful for developers and GIS specialists who need to work with geographic data across different standards.
Here's a basic example of how to use the GeoWKTer library:
// Initialize the GeoWKTer instance
let geoWKTer = new GeoWKTer();
// Example WKT input
let wktText = `
GEOMETRYCOLLECTION(POINT(4 6), LINESTRING(4 6, 7 10))
GEOMETRYCOLLECTION(POLYGON((8 4, 11 4, 9 7, 8 4)))
`;
// Convert WKT to GeoJSON
let wktDataArray = geoWKTer.read(wktText, 'Example Label');
let geoJsonData = geoWKTer.toGeoJSON(wktDataArray);
// Output GeoJSON
console.log(JSON.stringify(geoJsonData, null, 2));
read(wktText, label): Parses a WKT string and returns an array of geometry objects. It splits multi-line WKT text and labels each geometry.
toGeoJSON(dataArray): Converts the parsed WKT data array into a GeoJSON FeatureCollection.
