I'm working with fish distribution data, and have combined several 24k habitat maps into a single layer that I'll call "critical habitat"
In merging multiple distributions into one dataset, there are line segments that overlap one another.
Part of my project involves measuring the stream mileage in this "critical habitat" data set, but because there are stream segments with overlapping geometry, I'm unable to simply calculate each stream length and sum the for the whole dataset. I believe doing so would 'double-count' in those areas where there is feature overlap.
Is there a way to merge these multiple overlapping features into one, or is there any way to accuracy calculate the total feature extent while avoiding any 'double-counting'?
