View Full Version : Photoshop need help with map area measuring.
I just wanted to figure out what is the area (miles squared) of a specific area selection on the map. The trouble is that is it not exactly a square. Does anyone know how do I figure it out are (maybe in pixels)?

if you go in window/histogram you can show the number of pixel of a selected zone. Click on the triangle with tree horizontal lines and select show statistics in the menu.
like this (I have PS CS3) : 57510
To get the size of the area you will need to find the worth of 1 pixel in miles/km depending on the scale of your map.
I tried it and it makes no sense. I selected an area an it gave me 70,000 pxls then I selected as smaller portion of that area (2/3) and it gave me 150,000 pxls???? Am I doing something wrong? (I was using lasso tool)
Ok got it I didn't notice the recalculation error message at first. Thanks a lot for the info!
