What I need

I need to convert a list of markers to a tile layer

I've been googleing without success how to do this. Anyone has faced this problem and has a nice easy solution?

Why I need it

I've developed a HTML application that displays a map. This map has many fixed markers (they do not change in time). Due to that:

  1. I want to speed up the application
  2. I want to hide the marker position from malicious users (so they can't use the information I've gathered for they're own porpose)

I want to convert the markers to a tile layer.

Your "Question" looks like it is asking three questions: 1. How to speed up the application? 2. How to hide the marker position from malicious users 3. How to convert the markers to a tile layer? My recommendation would be that three Questions be posted. – PolyGeo Jun 27 '13 at 10:34
@PolyGeo My question is How to convert the markers to a tile layer, I've posted the other things to contextualize. – Mateu Jun 27 '13 at 10:50
That changes my recommendation to using that as the title of your question and editing the body of it to make that more obvious. – PolyGeo Jun 27 '13 at 10:53

There is no need to reinvent the wheel. Among the solutions for too many markers, there is one called Fusion Table Layers. They act as a layer, which is rendered at Google servers - so it is very fast.

You can find live examples in the Google Developer's Docs.

If he wants to use the Google Fusion Tables layer, the table he uses will have to be shared. That means that I (as a malicious user) can simply look at his code, grab the table id from it, go to the fusion table and download the whole stuff in like 5 minutes. – Tamas Jul 3 '13 at 22:18
