Using the Line Density tool on a geologic fault layer, I now have a density raster. Great, exactly what I wanted. Now I need to be able to do a probability density analysis by calculating an areal distribution or pixel count for each of the density classes. In other words, my fault densities range from <= .015 km/sq km up to <= .15 with .015 breaks from the low to the high. Now I need to know what percent of my map (world) is covered by each of the densities. It seems that I should be able to get a pixel count for each of the density classes. e.g. Pixel count for pixels with density <= .015, pixel count for densities > .015 and <= .030, etc. Thank you.
