turf-intersect

find the intersection of spatial features

turf.intersect(poly1, poly2)

Takes two Polygon|polygons and finds their intersection. If they share a border, returns the border; if they don't intersect, returns undefined.

Parameters

| parameter | type | description | | ——— | ——————– | —————— | | poly1 | Feature. | the first polygon | | poly2 | Feature. | the second polygon |

Example

poly1 = {
ype": "Feature",
roperties": {
"fill": "#0f0"

eometry": {
"type": "Polygon",
"coordinates": [[
  [-122.801742, 45.48565],
  [-122.801742, 45.60491],
  [-122.584762, 45.60491],
  [-122.584762, 45.48565],
  [-122.801742, 45.48565]
]]


poly2 = {
ype": "Feature",
roperties": {
"fill": "#00f"

eometry": {
"type": "Polygon",
"coordinates": [[
  [-122.520217, 45.535693],
  [-122.64038, 45.553967],
  [-122.720031, 45.526554],
  [-122.669906, 45.507309],
  [-122.723464, 45.446643],
  [-122.532577, 45.408574],
  [-122.487258, 45.477466],
  [-122.520217, 45.535693]
]]



polygons = {
ype": "FeatureCollection",
eatures": [poly1, poly2]


intersection = turf.intersect(poly1, poly2);

olygons

ntersection

Returns Feature.<Polygon>,Feature.<MultiLineString>, if poly1 and poly2 overlap, returns a Polygon feature representing the area they overlap; if poly1 and poly2 do not overlap, returns undefined; if poly1 and poly2 share a border, a MultiLineString of the locations where their borders are shared

Installation

Requires nodejs.
