Dear colleagues,<br><br>i have problems with ST_difference operator.<br>I have imported two *.shp files in postgis databas, country(polygon) and region of country(polygon).<br>I have run ST_difference query and the result was as i expected, but result was also part of <br>
both polygons, more precise some of boundary lines that both polygons contains.<br>I have checked geometries in AutoCAD and both geometries are similar, line on line, point on point.<br>Than I run queries in postgis to show me Geometry as text of both polygons and result of ST-difference. And all geometries contained same coordinates.<br>
<br>I hope that you have understand my problem and thank you for your help.<br><br>Marko<br><br> <br>
