*pointsWithinPolygon* on Trufjs
I'm trying to get some point inside multiple polygon using pointsWithinPolygon in turfjs, but the result is unexpected.
Is there any chance that pointsWithinPolygon isn't compatible with FeatureCollection?
Here is the example of my usage.
let points =
"type": "Point",
"coordinates": [
106.866995, -6.261513
]
let filter =
"type": "FeatureCollection",
"features": [
"type": "Feature",
"properties":
"IdArea": 4
,
"geometry":
"type": "Polygon",
"coordinates": [
[
[
106.314674,
-6.6348689124
],
[
107.5781628906,
-6.6348689124
],
[
107.5781628906,
-5.9742195859
],
[
106.314674,
-5.9742195859
],
[
106.314674,
-6.6348689124
]
]
]
]
let result = turf.pointsWithinPolygon(points, filter);
console.log(result);

Result: geojson with empty feature Expected: one point that intersect with the polygon, in this case the result supposed to be geojson with one point feature

You are trying to use geoJsons as inputs to turf's pointsWithinPolygons function.
The function takes a turf.points array of points, and a turf.polygon array of polygon vertices.
Based on the variables you established, you would need to call:
let result = turf.pointsWithinPolygon(turf.points([points.coordinates]), turf.polygon(filter.features.geometry.coordinates));
