Transect
Encyclopedia
A transect is a path along which one records and counts occurrences of the phenomena of study (e.g. plants noting each instance).
It 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. This results in an estimate of the area covered, an estimate of the way in which detectability increases from probability 0 to 1 as one approaches the path. Using these two figures one can arrive at an estimate of the actual density of objects.
The estimation of the abundance of biological populations (such as terrestrial mammal species) can be achieved using a number of different types of transect methods, such as strip transects, line transects
, belt transect
s, point transects and curved line transects.

town planners use the term transect
to refer to the varieties of land use from an urban core to a rural boundary. General New Urban transect classifications (from highest to lowest density) are: urban core, urban centre, general urban, suburban, rural, and natural.

Line-intercept sampling
In statistics, line-intercept sampling is a method of sampling elements in a region whereby an element is sampled if a chosen line segment, called a “transect”, intersects the element ....
, belt transect
Belt transect
Belt transects are used in biology to investigate the distribution of organisms in relation to a certain area, such as the seashore or a meadow. It records all the species found between two lines and how far they are for a certain place or area and how many of them there are...
s, point transects and curved line transects.

New urbanism
New Urbanism is an urban design movement, which promotes walkable neighborhoods that contain a range of housing and job types. It arose in the United States in the early 1980s, and has gradually continued to reform many aspects of real estate development, urban planning, and municipal land-use...

Transect (urban)
The urban-to-rural transect is an urban planning model created by New Urbanist Andrés Duany. The transect defines a series of zones that transition from sparse rural farmhouses to the dense urban core. Each zone is fractal in that it contains a similar transition from the edge to the center of the...
