I have observed some unusual behaviour with the Clean command.
I am running MapInfo 64-bit version 16.0.3
I have a table containing one record, a very large polygon, which is the result of buffering railway tracks.
The original .MAP had a file size of 5,789 KB
The original polygon had 728,840 nodes
I ran the Clean command on the table (without the Overlap or Gap Area keywords)
The new .MAP had a file size of 11,455 KB
The new polygon had 713,647 nodes
The change in number of nodes does not worry me. It is almost the same, and is easily explained by being a result of cleaning.
But, why has the .MAP file doubled in size? The number of nodes has not doubled. Is there something different in the way the geometry has been stored?
