Cone Generation

Spatial Analyst: Cones in a Random Pattern

Cones_pat = abs(eucdistance(con((\$\$ROWMAP mod int(normal() * 1 + 20) eq 0) and (\$\$COLMAP mod int(normal() * 1 + 20) eq 0),255),#,#,10,#) - 10) * (40 / 10)

Class objects by pattern by class Spatial analyst: Generate objects in a random pattern within the aspen

class

Raster Calculator: aspens_pat = eucdistance(con((\$\$ROWMAP mod int(normal() * 1 + 20) eq 0) and (\$\$COLMAP mod int(normal() * 1 + 20) eq 0) and [k_aspens] > 0,255),#,#,10,#)

Raster Calculator: esri_aspen = sqrt(pow(10,2) - pow([aspens_pat],2))

The result

Bump mapping

• (eucdistance(con( (\$\$rowmap mod int(normal() * 5 + 10) eq 0) and (\$\$colmap mod int(normal() * 5 + 10) eq 0),255),#,#,60,#)) * (-20 / 10) + 120
