How to use Maptiler to display tiles in Google Map

问题:

I have an image 1810x14871 png file, and I would like to display it as tiles on Google maps.

I'm using Maptiler, I would like to check with you few points:

1) Since I would like to display it on Google maps. Hence, in first screen I have to select "Mercator tiles", right?

2) In the coordinate System screen, my image is based on WGS84 projection. Hence, Do I need to select WGs84, or "Web Mercator", or UTM Projected?

3) In Geographical Location page, I selected "Load from World file", I created a .wld file with the following content: 0.2751031636863824 0.00000 0.00000 -0.26898567682063484 611289.7255515818 2614249.2935071616

Is it OK? please advice if I made a mistake somewhere, because tiles is not displayed on Google maps.

Thanking you.

1) yes, choose mercator tiles

2) WGS84 is default, so just click on set in the coordinate system box

3) There is a specification from ESRI how to save a worldfile: http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?pid=3034&topicname=World_files_for_raster_datasets

In your case I would maybe try visual georeferencing - will be quicker, here is how to do it: https://www.youtube.com/watch?v=eJxdCe9CNYg
