Sample Plotter

Generate sample points for a study area and all in your browser!

This is a small project to provide a web app to generate sample plots given an area of interest.

Webapp: sampleplotter.com

Sample Types:

Random Systematic Equidistant
sample_type Description
random Randomly creates the specified number of points.
systematic Given a target number of points (n), a systematic grid of points is created. A between point distance (d) is calculated to get the total number of points as close to n as possible. Initial point is randomly chosen between 0 and d for both x and y axes.
equidistant Given a number of points (n), a systematic triangular grid of points is created. Points are equidistant from each other. A between point distance (d) is calculated to get the total number of points as close to n as possible. Initial point is randomly chosen between 0 and d for both x and y axes.

Check Topology:

If "check_topology" is on, as close to n points as possible will be created only within study area.

Random Systematic Equidistant

Rotation:

Rotation in degrees of point array in counter-clockwise direction about extent center.
