Surveying linear features e.g river banks

Submitted by BiodiversityOverton on

Hi, just started using irecord and getting to grips with it!  We'd like to use it for recording a water vole survey. Is there any way of identifying linear features i.e a stretch of river as opposed to general areas e.g 100 metre squares? Also no water voles seen but evidence of presence recorded i.e. latrines and feeding sites.
