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.
回答1:
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
