Hello,
please, I wanna solve one problem with line elevation on wastewater network. I have really big network of lines in 2D, but every line has 2 attributes (BOTTOM_ELEVATION_FIRST - elevation of first line vertex and BOTTOM_ELEVATION_LAST - elevation of last line vertex). Unfortunately, values of these 2 attributes are not filled for all features. So, I have situation when some features have both values, some features have just one value and some features have none values. :-/ What I need is to join lines according to fact if the attribute of elevation is filled or not - the goal is getting lines which have filled both attribute values.
Do you have any idea, how to figure out this issue, please?
Thank You so much!
Lubo
