Boundary Observations vs Boundary Lines
Boundary observation connectivity is often the same as parcel or boundary line topology but
- Some boundary lines don't have observations (eg. the straight black lines 2, 3, 4, 5) below
- Some observations cover more than one boundary line (eg. the red, curved and dashed lines 2, 3 ,4, 5, 6) below
- Landonline does not create polygons from loops of observations
as polygons but it does create parcel polygons from loops of boundary
lines.
