This sample demonstrates the use of topology functionality (CreateShape,
TGIS_Topology.Create and TGIS_Topology.SplitByArc functions) in the TatukGIS
Developer Kernel for ASP.NET to split a polygon shape into multiple polygons
using a splitting line drawn by the on-line user.
To split polygon simply draw the splitting line by clicking in the map window.
The splitting line can be complex, formed with an unlimited number of vertices,
and can cut the polygon into more than just two shapes. Click on the "Split
Shape" button to render the result of the splitting operation. To start again
from the beginning, just click "Create New Line" button.
