XXII. Common Sampling Patterns

Question 1

What sampling pattern involves acquisition of samples that are equally spaced apart, both vertically and horizontally.

Answer 1

grid sampling pattern (or systematic grid sampling)

Question 2

Simplest grid design because all the samples are equally spaced apart vertically and horizontally.

Answer 2

Regular Grid

Question 3

Samples are equally apart horizontally. Every other sample line is offset one half sample spacing which decreases the diagonal spacing between samples.

Answer 3

Staggered Grid

Question 4

Each sample has same distance of away from each surrounding sample. This pattern is sometimes called a triangular grid because 3 nearest samples form an equilateral triangle.

Answer 4

Equidistant Grid
