I found a way to calculate area more easily, without Photoshop.

1) Color your map or whatever so that what you want to measure is white and the rest is black.

2) Upload the black and white map.

3) Type in into any random article and press "Preview."

4) Take the color's RGB values (using Digital ColorMeter in Macs), or else find a program that will do so, such as Paint. Find the speck and hover over it.

5) If it can give you the RGB percentages, there's your percentage of the whole picture that has what you want to measure.

Notes:


 * If you can only get the RGB value that goes from 0-255, simply multiply by 100 / 255 or about 0.392156863.


 * In some computers, windows will cast a "shadow," which may disrupt your results. Make sure that any windows are clear from the dot.  This is mostly Macs, though.


 * To calculate how many pixels are white in your picture, multiply the percentage by height and width. ~
