Boundary Changes and Data Capture
Graphical editing of land parcels is fully topological and provides the user with a rich set of functions for changing the existing parcel boundaries and data capture of the newly declared parcels.
It includes the following functions:
add polygon,
change border,
join polygons,
split a polygon,
make a hole in a polygon,
fill a hole in a polygon,
change polygon attributes.
Additional functions can be defined and easily implemented when the need arises. In cases of boundary disputes or explicit doubly-declared areas, topology checking can be disabled while editing;
however, the polygons resulting from such editing are marked and can later be retrieved when resolving the dispute or excluded when calculating the area eligible for payments.
