How to use SVG markers in Google Maps API v3

Question

Can I use my converted image svg as google map icon  I was converting my png image to svg and I want to use this like google map symbol that can be rotated  I already tried to use the google map symbol but I want to have an icon like car  man  etc    That s why I converted my some png files to svg  just like this example site what does he use for these http   www goprotravelling com

As mentioned by others in this thread  don t forget to explicitly set the width and height attributes in the svg like so    lt svg id  some id  data-name  some name  xmlns  http   www w3 org 2000 svg       viewBox  0 0 26 42       width  26px  height  42px  gt    if you don t do that no js manipulation can help you as gmaps will not have a frame of reference and always use a standard size    i know it has been mentioned in some comments  but they are easy to miss  This information helped me in various cases

Yes you can use an  svg file for the icon just like you can  png or another image file format  Just set the url of the icon to the directory where the  svg file is located  For example   var icon             url   path to images car svg           size  new google maps Size sizeX  sizeY           origin  new google maps Point 0  0           anchor  new google maps Point sizeX 2  sizeY 2      var marker   new google maps Marker           position  event latLng          map  map          draggable  false          icon  icon

Things are going better  right now you can use SVG files           marker   new google maps Marker               position   lat  36 720426  lng  -4 412573               map  map              draggable  true              icon   img tree svg

If you need a full svg not only a path and you want it to be modifiable on client side  e g  change text  hide details       you can use an alternative data  URL  with included svg   var svg     lt svg width  400  height  110  gt  lt rect width  300  height  100    gt  lt  svg gt    icon url    data image svg xml charset UTF-8 base64     btoa svg     JavaScript  Firefox  btoa   is used to get the base64 encoding from the SVG text  Your may also use http   dopiaza org tools datauri index php to generate base data URLs   Here is a full example jsfiddle    lt  DOCTYPE html gt   lt html gt       lt head gt           lt meta http-equiv  content-type  content  text html  charset UTF-8    gt           lt script src  http   maps google com maps api js sensor false  type  text javascript  gt  lt  script gt       lt  head gt       lt body gt           lt div id  map  style  width  500px  height  400px   gt  lt  div gt           lt script type  text javascript  gt              var map   new google maps Map document getElementById  map                      zoom  10                  center  new google maps LatLng -33 92  151 25                   mapTypeId  google maps MapTypeId ROADMAP                              var template                       lt  xml version  1 0   gt                          lt svg width  26px  height  26px  viewBox  0 0 100 100  version  1 1  xmlns  http   www w3 org 2000 svg  gt                              lt circle stroke   222  fill     color     cx  50  cy  50  r  35   gt                          lt  svg gt                     join   n                var svg   template replace     color        800                 var docMarker   new google maps Marker                   position  new google maps LatLng -33 92  151 25                   map  map                  title   Dynamic SVG Marker                   icon    url   data image svg xml charset UTF-8     encodeURIComponent svg   scaledSize  new google maps Size 20  20     optimized  false                              var docMarker   new google maps Marker                   position  new google maps LatLng -33 95  151 25                   map  map                  title   Dynamic SVG Marker                   icon    url   data image svg xml charset UTF-8 base64     btoa svg   scaledSize  new google maps Size 20  20     optimized  false                          lt  script gt       lt  body gt   lt  html gt    Additional Information can be found here   Avoid base64 encoding   In order to avoid base64 encoding you can replace  data image svg xml charset UTF-8 base64     btoa svg  with  data image svg xml charset UTF-8     encodeURIComponent svg   This should work with modern browsers down to IE9  The advantage is that encodeURIComponent is a default js function and available in all modern browsers  You might also get smaller links but you need to test this and consider to use   instead of   in your svg    Also see Optimizing SVGs in data URIs for additional info   IE support  In order to support SVG Markers in IE one needs two small adaptions as described here  SVG Markers in IE  I updated the example code to support IE

You can render your icon using the SVG Path notation   See Google documentation for more information   Here is a basic example   var icon          path   M-20 0a20 20 0 1 0 40 0a20 20 0 1 0 -40 0       fillColor    FF0000       fillOpacity   6      anchor  new google maps Point 0 0       strokeWeight  0      scale  1    var marker   new google maps Marker       position  event latLng      map  map      draggable  false      icon  icon       Here is a working example on how to display and scale a marker SVG icon   JSFiddle demo  Edit   Another example here with a complex icon   JSFiddle demo  Edit 2   And here is how you can have a SVG file as an icon   JSFiddle demo

I know this post is a bit old  but I have seen so much bad information on this at SO that I could scream  So I just gotta throw my two cents in with a whole different approach that I know works  as I use it reliably on many maps  Besides that  I believe the OP wanted the ability to rotate the arrow marker around the map point as well  which is different than rotating the icon around it s own x y axis which will change where the arrow marker points to on the map   First  remember we are playing with Google maps and SVG  so we must accomodate the way in which Google deploys it s implementation of SVG for markers  or actually symbols   Google sets its anchor for the SVG marker image at 0 0 which IS NOT the upper left corner of the SVG viewBox  In order to get around this  you must draw your SVG image a bit differently to give Google what it wants    yes the answer is in the way you actually create the SVG path in your SVG editor  Illustrator  Inkscape  etc       The first step  is to get rid of the viewBox  This can be done by setting the viewBox in your XML to 0    that s right  just one zero instead of the usual four arguments for the viewBox  This turns the view box off  and yes  this is semantically correct   You will probably notice the size of your image jump immeadiately when you do this  and that is because the svg no longer has a base  the viewBox  to scale the image  So we create that reference directly  by setting the width and height to the actual number of pixels you wish your image to be in the XML editor of your SVG editor   By setting the width and height of the svg image in the XML editor you create a baseline for scaling of the image  and this size becomes a value of 1 for the marker scale properties by default  You can see the advantage this has for dynamic scaling of the marker   Now that you have your image sized  move the image until the part of the image you wish to have as the anchor is over the 0 0 coordinates of the svg editor  Once you have done this copy the value of the d attribute of the svg path  You will notice about half of the numbers are negative  which is the result of aligning your anchor point for the 0 0 of the image instead of the viewBox   Using this technique will then let you rotate the marker correctly  around the lat and lng point on the map  This is the only reliable way to bind the point on the svg marker you want to the lat and long of the marker location   I tried to make a JSFiddle for this  but there is some bug in there implementation  one of the reasons I am not so fond of reinterpreted code  So instead  I have included a fully self-contained example below that you can try out  adapt  and use as a reference  This is the same code I tried at JSFiddle that failed  yet it sails through Firebug without a whimper        lt  DOCTYPE html gt       lt html gt       lt head gt       lt meta charset  utf-8    gt       lt meta name  viewport   content  width device-width  initial-scale 1    gt
