PRINCIPLES
OF LANDSCAPE CLASSIFICATION
This chapter describes the last step in the characterisation process,
namely classifying and describing landscape character. It looks at:
the
principles and practice of landscape classification;
terminology used,
with the aim of encouraging greater consistency amongst
practitioners;
dealing with
boundaries between landscape character types
and areas;
description of
character.
Landscape
classification is central to Landscape Character Assessment and is
concerned with the process of dividing landscape into areas of
distinct, recognisable and consistent common character, and grouping
areas of similar character together. Classification can be carried out
at any scale and so can provide information on the extent and
distribution of different types and areas of landscape from the
national to the local scale. Classification provides the central
framework on which subsequent judgements about landscape character are
based.
Classification
requires the identification of patterns in the landscape, created by
the way in which the natural and human influences on the landscape
interact to create character. Methods of classification are simply ways
of recognising and recording these patterns. Broadly, classification
approaches take three forms, and there may be a variety of combinations
of these:
professional and/or stakeholder judgement about boundaries based on the
manual manipulation of all data collected;
use of GIS for the
manipulation of map data and computer classification
techniques to devise the classes of landscape
character and the appropriate
boundaries;
use of GIS to
assist in the manipulation and analysis of map
data to help inform
professional and/or stakeholder judgements
about the boundaries of landscape
classes.
