Custom icons for kml layer using in Google maps Api - parsing

I want to display data from kml file, which is situated here http://maps.google.com/maps/ms?f=q&msa=0&output=kml&msid=201434694813577429889.0004ba2d12b7538131e5e .
It is output from MyPlaces. I want to do more stuff with it - change icons, use clustering and so on, so embedding is not good solution.
I've tried to load the file using KmlLayer in GoogleMapsApi, which works, but I don't know, how to change icons and how to get data for each marker (coordinates, description, ..).
Actually, what I need is just the access to the data in kml, I am able to do all other programming on my own. The file is continuously changing so I need to do all the stuff online.

You could use a 3rd party KML parser (through a proxy) like geoxml3 or geoxml-v3. They render the KML using native Google Maps Javascript API v3 objects, you can modify those using the Google Maps Javascript API. When you do that you lose the benefit of KmlLayer's tile based rendering, so with complex KML, you may have performance issues.
example with your KML (seems to have a character encoding issue)

How to show GeoJson javascript data as layer in Google Maps in iOS swift

I have requirement that is, I have to show GeoJson data (java script file) as a layer in Google maps either using Native or Web view. I have checked few forums, as per they said, it is possible only for Android to load java script for loading data layer in Google maps.
So, my requirement is, I want to show some java script which contains geojson data as layer and then after that, I have to draw a route or path from start point to end point in map(like user started walking from 1 place to other place around 1 to 10 kms like footsteps).
I seen in Google maps forum, only Android and Web possible this kind requirement.
And I have checked MapBox library too, I am not sure whether it will help to my requirement. But, my preference is Google Maps.
Anyone can suggest me how to achieve this?

Generating Images from maps

How do you capture an image of a user generated map, like one created using Leaflet.js?
Here is my example:
I have a website that generates a map.
I want to save an image of that map
e.g. when the user shares their profile, the preview image is of their map.
I know facebook, Strava, and most other services show images of a user map in their news feeds instead of showing interactive maps.
The problem
The map is generated client side, so grabbing an image of the map serverside isn't possible
Possible Solution
Once a map is generated, use PhantomJS to capture a screenshot of the map, and crop out the rest of the website.
Question
Since this is such a common thing to do, is anyone aware of a better or more standard way of grabbing these screenshots? I've seen things like the mapbox static API, but that doesn't capture the custom pins and line features on my maps.
I'm using rails for the back end.
You can make your map to be able to read the url params and set its state from it. When the user changes something on the map, the map's state is saved as url parameters and then send it/store it on the server for PhantomJS to generate it.
E.g.
&coords=123.123,10.123,54.54,45.11&zoom_level=5&....

Displaying "my map" layers in Google maps for iOS SDK

Is there a way to display (and search in markers data) "my maps" layer in a GMSMapView in the Google maps SDK for iOS? Searched docs but couldn't find.
"my maps" are basically custom maps with additional layers you can create on top of a google map region, I want to use a public one that has tons of layers and markers already in place (I do not want recreate them programmatically).
basic example for "my maps" data:

thanks!
Unfortunately it looks like there is no API for accessing My Maps, see here:
Google maps API - get my custom map
However, it looks like it's possible to convert your My Map into KML, either a one-time download or a live link to the current map content, see here:
https://support.google.com/mymaps/answer/3109452?hl=en
(I found this via Add Google "My Maps" Layer to Google Maps Javascript API, although the UI to get the KML has since changed from that answer in 2009).
Once you have the KML you can't add it directly to your map, but you can parse it and then add each of the markers etc, see here:

Display kml file on a map

In my application I would like to display a kml file over the google maps using google map api v3.
While I was searching for the solution I came across geoxml3, BUT i don't really understood its use and for what is used.
Can anyone explain if its the solution to use geoxml3 to overlay kml file stored locally in my application.
Or else what is the main use of geoxml3?
The Google Maps API v3 method for displaying KML (using tile based rendering) is KmlLayer
Developer's Guide (including examples)
geoxml3 was developed before KmlLayer was released, it parses KML to native Google Maps API objects (losing the benefit of tile based rendering, but allowing access to individual objects)
KmlLayer requires the KML be accessible by Google's servers. If the file is local, geoxml3 can access local files (under some conditions, with some browsers) and render them on a Google Map, but remember, unless you have a Business License, to meet the terms of use, your map must be publicly available (or you app must be, IANAL, read the terms for yourself).
geoxml3 is a KML processor for use with the Google Maps v3 API. It allows you to render KML data on a Google Maps application. This KML data can be used to generate markers, polylines, or whatever other objects you wish.

Google Maps API

I am building a twitter, google maps mash-up.
I am trying add user's twitter profile picture to the map as a custom marker,
I know how to add custom markers from images but was wondering if there was any easy way of adding a different image for every marker.
You can make google maps use a kml file which can be dynamically generated based on current twitter pics. A kml file is a basically an xml file that contains geo-data.
The following link will provide you with examples, look at Marker Icons. There is also sample kml format for what your placemark mark up should look like. It consists of the coordinates of the marker and the picture you want to use.
