2.0 Objectives
2.1 Objective # 1
-
To identify the active porosity in each slides given - a total of 4 slides.
2.2 Objective # 2
-
To have at least three random horizontal transects on each soil slides
to figure out the diameter of each pore cells (geometric mean of pore diameter)
- a total of 4 slides.
Both objectives use Idrisi to try to automate the identifications and counts
in each slide. Java program will be use for Objective # 2 to count
the porosity diameters in each slide.
2.3 Resolution of the four slides
-
Scanned slide as 600 dpi.
600 dpi = 1"
1102 columns/600" = 1.84columns per inch to cm = 4.67columns per cm/1102
columns = 4.24*10-3cm/100cm = 4.23*10-5 x 1000000u
=
42.4u
Each pixel equal 42.4u by 42.4u
Each pixel equal 42.3u by 42.3u
Each pixel equal 42.3u by 42.3u
Each pixel equal 42.3u by 42.3u
