In practice, systematic sampling is used on account of its simplicity and convenience. It's easy to explain to the people doing the actual work. It can be justified theoretically wherever the population from which units are to be sampled systematically are randomly distributed. It can be used for sampling households, sampling callers on a telephone line, sampling plants along a transect in (say) a field, sampling people passing through customs, and so on.
a line transect looks like a few lines and dots used to mark a certain area.
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
Sampling and Non sampling errors
Random Sampling
It means cut crossways.

Please transect the frog or fail the course. Please do not transect the grass. How's the transect today?
The belt transect method of vegetation is a field sampling technique used to quantify plant species composition, abundance, and diversity in a specific area. It involves laying down a belt or line across the habitat and recording all plant species that lie within or intersect the line. This method helps researchers obtain a systematic and representative sample of the vegetation in an area.
A transect is a slice or path through the environment. It may be any dimension from a few inches to an entire region. To "take a transect" one would use sampling methods such as the Dissect and Quadrat. The entire transect does not have to be analyzed, only typical portions of it. For example, in sampling urbanism to write a design/zoning code, the analysts identify the rural-to-urban transect of a given town or neighborhood, note the distinct habitat zones along the transect, and sample the built elements in typical portions of each habitat. This is done by measurement and identifying types visually, both on the ground and from aerial mapping. The "DNA" of the community may then be written into a code for the future. The technique originated in the ecological and biological sciences, as they sample the many elements that co-exist in a habitat or series of habitats. Both the urban and natural versions of transect analysis help identify the individual elements necessary to make that habitat healthy and sustainable for its human residents and plant/animal residents respectively.
Relative abundance is typically calculated by dividing the number of individuals of a particular species by the total number of individuals in a community and expressing this as a percentage. This helps to compare the presence of different species in a community. Additional methods, such as quadrat sampling or transect sampling, can be used to estimate relative abundance in ecological studies.
A beach transect is a geographical technique in which the angle of a beach is measured with a ranging pole and a clinometer.
