I want to be able to draw a circle with 50km radius and then fill the circle with values corresponding to the free space loss formula below:
FSPL(db)=20 log10(d)+20log10(f)+32.44
a circle of 50km around the "west Myara site" and then for every pixel(I guess) I would like to know its corresponding FSPL value and have it colored accordingly.
would I have to convert the polygon to a raster and then use the raster calculator to produce the values of each cell/pixel? if thats the case I would need to find the distance of the pixel/cell from the center point (in this case "west of Myara site" point) and how would I do that ?
