I am looking to calculate the sum of overlapping polylines in a field. I have fish distribution data and I would like to create a richness field to calculate the number of species on each stream segment.

I have previously converted all of the polylines to rasters and used the weighted sum tool, however, I would like the richness number stored back in a merged shapefile. The final result will be a web mapping application and the pixelated raster on the web is less than aesthetically appealing.

Any suggestions would be greatly appreciated,
