Step 1c : Buffer the rivers

The logging area must not be within 1km of the rivers. So we simply buffer the rivers out to 100m as well , in ARC type :

Arc:  buffer riverline waterbuf2 # # 1000 # line
Buffering......
Sorting.......
Intersecting.....
Assembling Polygons....
Creating New Labels.....
Finding inside polygons.....
Dissolving ....
Creating waterbuf2.PAT...
Arc:

Look at the resulting buffer in ARCPLOT, type :

Arcplot: clear
Arcplot: linecolor 1
Arcplot: arcs waterbuf2
Arcplot: linecolor 2
Arcplot : arcs riverline

Step 1c : Buffer the shrine

The logging area must not be within 10km of the shrine. So we need to create a buffer of 10km around the shrine. At the ARC prompt type :

Arc: buffer shrinepoint shrinebuff # # 10000 # point
 Buffering ...
 Sorting...
 Intersecting...
 Assembling polygons...
 Creating new labels...
 Finding inside polygons...
 Dissolving...
 Creating shrinebuff.PAT...
Arc: 

Now look at all the buffers we have created . At the ARCPLOT prompt type :

Arcplot: clear
Arcplot: arcs waterbuff1
Arcplot: arcs waterbuff2
Arcplot: arcs shrinebuff
Arcplot: linecolor 4 
Arcplot: arcs roadbuff
Arcplot:
