Slope and Aspect

• Already covered in detail
• Remember that slope can be calculated in two ways
• Degrees
• AND WE WILL ALWAYS WORK IN

4
And degrees is default!!!
5
RECLASS

• The ability to change any or all values in an
  image to different values.
• Several ways
• RECLASS module
• Reclass file (.rcl)
• ASSIGN (Later)

6
Image Similarity

• Three methods
• Use REGRESSion. -- R
• If R1 then the relation between the images is
  perfect
• If R0 then there is NO relation between
• Use CROSSTAB image similarity
• Cramers V
• Kappa

7
Palettes

• Two tools make sure you get the right one
• Symbol Workshop -- vector stuff
• Symbol Workshop Palettes
• Where saved
