Seam lines autoclassified to power lines

Hi,

When we are bringing DSM data into global mapper as las files from photogrammetric software we are finding a strange phenomenon that certain areas, mainly seam lines but other areas too are being auto classified by the LiDAR module as power lines. We get round this by selecting the 'powerlines' and reclassifying them to ground points, then when we do 'autoclassify ground points' we check to option to reset ground points to unclassified.

just thought this a bit strange

thanks in advance
