Multiple peaks with peak_local_max

Thank you for you answer Josh,

these red dots are actually an array, where each cell has a coordinate x 
and y.
To be honest I wanted to export this red dots with the following structure:

590600,00 6890408,00 1019,04

This image I'm using each pixel has a geographic coordinate. But, at the 
moment I use the image in the scrip, the coordinates are lost and remains 
only basic pixel coordinates (i. e. 40, 412, 210).
I'm quite new at scikit and python. So I'm trying to learn things with 
practice.

Thanks for your attention
