Description Usage Arguments Details Value See Also Examples

Tool to support the selection of an adequate satellite spatial resolution. Evaluates how the change in spatial resolution changes the amount of samples and sample regions based on a set of coordinate pairs.

1	sMoveRes(x, y)

`x`	Object of class SpatialPoints or SpatialPointsDataFrame.
`y`	vector of spatial resolutions (unit depends on spatial projection).

Given a vector of pixel resolutions (y), the function determines the number of unique pixels and unique pixel regions after their temporal aggregation. For each spatial resolution, the function starts by converting x to unique pixel coordinates and labels them based on their spatial aggregation. Then, the function counts the number of samples and sample regions. The output of the function consists of:

stats - Summary statistics reporting on the number of unique samples and sample regions per spatial resolution.
plot - Plot representing the change in number of samples and sample regions per spatial resolution.

If x is a move or a moveStack object, the function will iterate through each unique dataset name and return a nested output where the elements of of the list are named in accordance with the oataset names.

A list.
