This is probably a silly question, but I am having a hard time finding good resources for this just by googling.
I have 3 different markers that I'd simply like to look different. Is there a good and simple tutorial for this? or could someone just paste some code to do that? I imagine its a one-liner kind of thing.
Thanks,
Alex
When you create your Marker, set the icon and shadow properties of the MarkerOptions to the images of your choice. There are lots of examples, this one might get you started.

So this question may seem hard to understand and very vague and that's because I have no other way of explaining this, so I'll try and describe what I want to achieve.
So essentially I want to create a character model (based from the protagonist of Minecraft, Steve). What I'd like this to serve as is a texture viewer from which a user enters his username into. A site that does is can be found here
See how the texture is displayed by a 3d blocky character? That is what I want to create, so essentially a blank 3d model where users textures will appear on when entered.
I'm not asking for entire code on this, I just need to some guidance as to how I would go about doing this.
Thanks for any and all help! If you got more questions I will try and answer them as best as I can. Thanks again!
In my experience, whenever trying to implement some graphics-related feature boils down to working with svg, or canvas, or just plain images. I would recommend that you look into using the HTML5 canvas element with maybe WebGL.
So I have been searching on google for over half an hour now trying to find an easy html clickable map without any JS if possible but I just can't find one that suits my needs. I just want it to be a map with all of the countries in a container or something so I can make a quiz for myself (I want my OWN one). I just thought it would be fun to try to make a quiz for myself but I just need a world map template.
I think MapBox Studio can help you.

It's easy to use, i don't need to explain a lot :)
I hope this is help you !
I have a map that I have many markers and some of them are overlapping so that I can hardly find the way to make it click.
I found the mapclustered grouping markers, but I do not really like that idea, I need to see them all.
Is there any way that when approaching the mouse pointer to those markers that are piled then they can be "opened" in some way to then to do click?
I hope someone can give me a clue how.
I found the answer to my question. There is a library that does just what I need. Called OverlappingMarkerSpiderfier.
It can be seen running here

it says how this is the easiest clustering posible, but I can't find any client side solution for this. Does anyone know for free open source, client side solution of grid based clustering for google maps markers ? i don't want MarkerClusterer.
I didn't find it, so i went and start coding my own solution. The first obvious request is that it has to be fast for up to at least 1000 markers loaded on map. Every zoom in out, move and soo on, will repeat procedure/function of clustering. Grid blocks are customizable, default value is 50*50 pixels.
Image below is showing what should the result look like.
I'm having problem with algoritem, now all I can think of to achive this is to itterate through all markers for each grid and ask if it is inside bounderies and then increase array of grid ++. This obviusly can't be done that way. There should be some hash or something that just one itteration through all markers would be needed and I would know in which grid specific marker belongs to.
I hope someone will give me a hint for algoritem I'm after. Thank you !
Seems like geohash is the answer to your problem, you even allude to that solution in your question. It's explained well here:
http://blog.trifork.com/2013/08/01/server-side-clustering-of-geo-points-on-a-map-using-elasticsearch/
I am actually exploring developing a similar clustering algo for Google Maps API v3. I'll post more if I actually get anywhere with it.
You can use a geohash or a space filling curve to reduce the dimension and reorder and hash a marker. On the server side you can use a point and a spatial index data stucture but you can also compute the geohash manually. Look for xkcd internet map comic and the hilbert curve to see how it works.
I have been searching everywhere but I could not find an answer. I
need to have drawing resizable polygons with mouse interaction but I
do not want irregular, overlapping or intersecting polygons in the
end.
Here is a simple example of drawing resizable polygons
http://www.wolfpil.de/polygon.html
You can easily create & resize polygons which is great. But I need an
extra functionality to detect intersections and NOT allowing weird
looking shapes/polygons.
You can see the problem in this video:

The only solution for that problem I found at http://www.wikimapia.org. They have added features to handle the problem.
You can see it in this video: http://www.youtube.com/watch?v=K7-K0k2D-2A
I spent 3 days trying out to achieve something like this. I have gone
through wikimapia's javascript code but it is way too complex for me
to understand.
In sum, it does not have to look as fancy as as wikimapia's. I just
need resizable polygons which do NOT intersect while resizing or
adding new points to it. Can you give me any suggestions how to
achieve that?
Thank in advance.
Depending on how many points that you allow, a naive, simple O(N^2) line intersection algorithm suffices. Algorithmically this is not the best solution, but for starting out it's the most accessible for a beginner in computational geometry.
For starter, see Wikipedia article on line segment intersection. One of its links has an easy to understand explanation on how to compute the intersection point of two line segments.
Good luck!
While this is not a complete answer, note that the example you supplied appears to be using the Geometry Controls from the GMaps Utility Library, which is an open source project hosted on Google Code.
