I'm getting mixed messages from the way my geometry is being displayed - and different editing/analysis tools produce inconsistent results. [ATTACH=CONFIG]27991[/ATTACH] The attached image shows a single polygon displayed with 'Radiation Overlay' style from the ESRI library. Notice how the hatching and the outer edge follow different paths.
Now, if I do an OUTSIDE_ONLY buffer I get the following result: [ATTACH=CONFIG]27992[/ATTACH] --the buffer follows the line of hatching
But if I do a FULL buffer then Clip out the centre it follows the outer edge of the original poly: [ATTACH=CONFIG]27993[/ATTACH] So I'm confused about which is correct and how my original poly is stored in the database.
It is not acceptable for me to have gaps or overlaps in my final geometry.
Does this happen with Shapefiles? I haven't noticed it.
I would like to make the switch to Geodatabases but this will be a deal breaker - I am aware of the X,Y tolerances but the change in geometry is ~30 times the tolerance. The worst part however is the inconsistency - I may be able to accept it if it was consistent but I cannot have overlap/underlaps in my geometry.
