Python Geosystem / KML / Google Earth

[Kasper Jepsen]

Hi,

I have used some time to look around the internet, but seems not to get me further, therefore i think i would ask in here :)

I would like to add an overlay picture in google maps, ny add it to KML file, that part i think i know how to do.

What i have issues with is to calculate the 4 corners of the picture.

If o know the center lat/lon and i want to add the picture (10m x 10m) with this position in the middle of the picture?

Also how to know how many pixels this picture have to be... maybe the ratio is enough and then it will scale it automatic.

I think this is mainly a issues of understanding the geo system, but also how to code it, what libraries are smartest to use etc.

Hope you can help me in any direction :)
