I have this spatial query in mysql:
select st_intersects(st_buffer(point(8.429614,45.017725),0.05),shape)
where shape is a column in db with geometry format. I don't understand what unity of measurement is used for the distance in st_buffer function. What represents 0.05, 5km?5miles? I have the radius express in km. I red the answer for this question that is similar to mine: What is the unit of measurement used in MySQL's spatial Buffer call? but i dont'understand the unity of measurement used in my case.
