Hello, My task is to ensure that 75% of a stream length is 'vegetated' to 30m. I am trying to follow a work flow that suggests segmenting a stream every 100m and then use Euclidean allocation to create various buffers. By segmenting and then buffering the stream I will then have 'evaluation units' that can be used to manipulate land cover. My question is, using python, how could I divide the stream segments of a shapefile into subsegments every 100m, having these sub-segments maintain a link to their original full stream segment. Once I have these subsegments, can a Euclidean allocation function be easily applied to attain evaluation units that maintain information about adjacent evaluation units? Any help on this one would be greatly appreciated 🙂

Hello, I have a land use shapefile that I am trying to modify in python. I have created a buffer around surface water polygons and I want to convert a percentage of the land use types that fall within the buffer to a specific land use. For example, within a 100m buffer of my stream I want to ensure that at least 10% of the region is 'naturally vegetated'. If it is not, then I want to convert 10% of changeable land (i.e. row crops) to 'vegetated'. If anyone could assist me with this one, it would be greatly appreciated. Thanks in advance, Bethany Thank-you Nobbir, this work flow has been very helpful:)
