Systematic sampling is almost identical to simple random sampling if the population list is randomized.
It can be guaranteed by detailed stratification or systematic sampling.
Systematic sampling Each unit in the sampling frame has an equal probability of being selected but selection is based on a predefined rule.

However, when the population list from which the sampleis drawn is large, simple random sampling may not be practical and more systematic sampling procedures should be considered.
This analog of random sampling or systematic sampling allows constructing regional random sampling under conditions of lack of sampling grounds under limited material and time resources6.

After a certain period of acceptable results(12 months or 10 lots,whichever comes first), the sampling frame may change from systematic sampling and testing of each lot, to random sampling of lots delivered to countries.
Illustrations of operational monitoring systems at the national level(e.g. Brazilian and Indian surveys and estimated deforestation rates, such as for the Brazilian Amazon) up to the regional/global level by remote sensing surveys were provided,followed by options for future monitoring based on systematic sampling.
In each completed enumeration area, following a full household listing, 20 households were selected, using systematic sampling with a random start, and 4 households were randomly allocated to each of the five treatment arms, translating into an initial allocation of 560 households per treatment arm.
This is accomplished through mapping of seamounts using multi-beam echo sounder, side-scan sonar and single- ormulti-channel seismic systems, systematic sampling using dredges and corers, bottom video and photography, water column sampling and laboratory analysis of crusts and substrates for composition and physical properties.
Random sampling approaches include both(1) simple or systematic random sampling where each sampling unit has the same chance of being selected; and,(2) cluster sampling approaches where the population is split up into sub-groups and sampling units are chosen randomly within clusters.
More generally, a systematic analysis of sampling errors can help to achieve significant quality improvements and/or cost savings in the compilation of indices.

Cluster sampling of classes can be achieved either by simple random sampling or systematic random sampling.
As most existing schemes for fixed-size sampling proportional to size are rather complicated, a systematic version is used instead.
These include simple random samples, systematic random sample, cluster samples, stratified samples and multistage sampling.
Accuracy: Overall agreement of a measurement to a known value, taking into account random and systematic error(precision and bias) of both sampling and analytical operations.
