Research direction

Start by locating the Java Turf and GeoJSON APIs corresponding to coordEach and toWgs84, then compare them with the JavaScript examples in this issue. Determine how coordinate traversal and coordinate conversion should fit the existing Mapbox Java API, and verify the behavior with suitable project tests. Done means both requested methods are available for the described GeoJSON transformation.

Description

jira-sync-complete

JavaScript code here , now，need to transfer it for Java. but Turf for Java hasn't been provided these methods("turf.coordEach" and "turf.toWgs84").
`let matrix = [
[1, 0, 0],
[0, 1, 0],
[-7497858.8300422, 295668.93016059976, 1]
]
var geojson;

if(trans){
$.getJSON('./xjlmk.geojson', null, function(data){
geojson = data;
transformGeo(geojson, matrix);
geojson = turf.toWgs84(geojson);
});
}

// geojson坐标配准
var transformGeo = function (features, matrix) {
var ret = [];
if(matrix.length != 3) return features;

turf.coordEach(features, function (currentCoord, coordIndex, featureIndex, multiFeatureIndex, geometryIndex) {

	var x = currentCoord[0] * matrix[0][0] + currentCoord[1] * matrix[1][0] + matrix[2][0];
	var y = currentCoord[0] * matrix[0][1] + currentCoord[1] * matrix[1][1] + matrix[2][1];

	currentCoord[0] = x;
	currentCoord[1] = y;
});

};`
