Classification layer accuracy and area report (for stratified random sampling)

Estimates map accuracy and area proportions for stratified random sampling as described in Stehman (2014): https://doi.org/10.1080/01431161.2014.930207. Observed and predicted categories are matched by name, if possible. Otherwise, categories are matched by order (in this case, a warning message is logged).

Parameters

Predicted classification layer [raster]

A classification layer that is to be assessed.

Observed categorized layer [layer]

A categorized layer representing a (ground truth) observation sample, that was aquired using a stratified random sampling approach.

Stratification layer [layer]

A stratification layer that was used for drawing the observation sample. If not defined, the classification layer is used as stratification layer.

Open output report in webbrowser after running algorithm [boolean]

Whether to open the output report in the web browser.

Default: True

Outputs

Output report [fileDestination]

Report file destination.
