As it so happens, I am reprogramming some functions in a MapBasic program at present and I am encountering problems with the coordinate shifts that have been discussed recently. In the program, the line is drawn into the cosmetic layer, the polygon in the editable layer. Both objects are extracted to variables for processing, where the polygon object is split by the line into two polygons. The process seems to work fine (BTW the extractnodes function is a great new feature). However, on closer inspection, there is a problem. When the split polygon objects are added back to the original layer, they have shifted about 4cm from the original object. This will mean that they no longer adjoin the neighbouring objects. The split also occurs about 4cm from the original. In light of the recent discussions, it all seems to make sense, but it does not help the situation. ?? Any suggestions?? Its 2 AM here so I am going to bed, but maybe tomorrow I will try overlaying nodes with neighbouring polygons etc. to see if that works... Or maybe buffer the polygons by 4cm and erase the result with the neighbouring polygons.
