#
#EXERCISE: HOW LONG ARE COMMON BOUNDARIES OF POLYGONS?
#
#
## Requires: GRASS 6.1-CVS from 13 Oct 2005 or later
##
## data: sudden infant deaths data from North Carolina
## data imported from SHAPE file with v.in.ogr
#
##let's have a look
# d.mon x0
# d.vect sids
#
##we work on a copy:
# g.copy vect=sids,sids_nc
#
##we add a second layer to the map which references the boundaries of
##polygons. In the vector geometry we generate an ID (category) for each
##boundary:
# v.category sids_nc out=sids_nc2 layer=2 type=boundary option=add
#
##Underlying idea:
##we'll fetch the IDs (categories) of the polygons left and right from
##each boundary and store it into the attribute table linked to layer 2.
##In general:
## cat_of_boundary | cat_of_left_polygon | cat_of_right_polygon | length_of_boundary
##
##We want only one category per boundary, that's why the sides check is
##needed (a boundary may consist of several pieces)
##
##So we create a new attribute table and link it to the new layer 2
##of the vector map:
# v.db.addtable sids_nc2 layer=2 col="left integer,right integer,length integer"
#
##Now we query the polygon/boundary relationsships and store it into
##the attribute table linked to layer 2:
# v.to.db map=sids_nc2 option=sides col=left,right layer=2
#
##Now we have unique categories for the boundaries and can calculate the
##lengths:
# v.to.db map=sids_nc2 option=length col=length layer=2
#
##Done.
#
##See the new attribute table containing the boundary lengths:
# v.db.select sids_nc2 layer=2
#
## verification (let's check boundary #193):
# d.vect sids_nc2 cat=193 layer=2 col=red type=boundary
# d.zoom
# d.measure
## LEN: 12756.00 meters
#
##what does the attribute table say:
# v.db.select sids_nc2 layer=2 | grep '^193'
##190|65|68|12814
#
##This is reasonably close since on screen digitization in d.measure
##isn't always that precise ...
