style='font-size:10.0pt;font-family:Arial;color:navy'>I have been trying for
months to find a way of selecting the records of a land based species that have
accidentally been recorded in the sea i.e. not on one of the land
polygons. I’ve tried qgis and mapinfo and not been able to find a
way of selecting records that are NOT on the land. Have tried adding a
sea layer but both mapinfo and qgis crash (out of memory) when trying to cookie
cut this to produce a sea only polygon. The very annoying thing is that I
did manage to do this once so know it is possible but just can’t remember
how and I’ve not been able to find any documentation that would help.<o:p></o:p></span></font></p>

covers the whole world.<o:p></o:p></span></font></p>
