javascript - Google Maps Json to GPX -


i'm trying coordinates google timeline convert them gpx format. there exist api can extract time , location google maps timeline json out?

the json-file looks this:

{   "locations" : [{     "timestampms" : "1383767355903",     "latitudee7" : 481848021,     "longitudee7" : 112554011,     "accuracy" : 100   }, {     "timestampms" : "1383767295887",     "latitudee7" : 481848003,     "longitudee7" : 112554027,     "accuracy" : 100   }] }

i think have coordinates in google pixels , need convert coordinate latlong. 

function latlng2point(latlng, map) {   var topright = map.getprojection().fromlatlngtopoint(map.getbounds().getnortheast());   var bottomleft = map.getprojection().fromlatlngtopoint(map.getbounds().getsouthwest());   var scale = math.pow(2, map.getzoom());   var worldpoint = map.getprojection().fromlatlngtopoint(latlng);   return new google.maps.point((worldpoint.x - bottomleft.x) * scale, (worldpoint.y - topright.y) * scale); }  function point2latlng(point, map) {   var topright = map.getprojection().fromlatlngtopoint(map.getbounds().getnortheast());   var bottomleft = map.getprojection().fromlatlngtopoint(map.getbounds().getsouthwest());   var scale = math.pow(2, map.getzoom());   var worldpoint = new google.maps.point(point.x / scale + bottomleft.x, point.y / scale + topright.y);   return map.getprojection().frompointtolatlng(worldpoint); }

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
