Transect Mapping
Transect mapping is a mapping which is done along a path, along which one counts and records
occurrences of the objects of study. A transect map, accomplished through a transect walk, is a
tool used by a group undertaking observation-based community improvement, which should
include informed community members and people with the technical skills to identify and
propose solutions to issues that are visibly manifested on a walk through the community. The
walk can take 1-3 hours, but advance planning is important to identify objectives and methods.
Transect mapping requires an observer to move along a fixed path and to count
occurrences along the path and, at the same time, obtain the distance of the object from the path.
Transect walks can supplement formal maps and data, but in cases where these do not exist, they
are an excellent tool for creating a record of environmental and human conditions.
