It also allows for calculations of four theoretical metrics of landscape complexity: a marginal entropy, a conditional entropy, a joint entropy, and a mutual information Nowosad and Stepinski Every function can be used in a piped workflow, as it always takes the data as the first argument and returns a tibble.

Due to an improved connected-component labelling algorithm landscapemetrics v1.

However, results for all metrics are identical. The resolution of a raster cell has to be in meters , as the package converts units internally and returns results in either meters, square meters or hectares. The second part of the name specifies the level patch - p , class - c or landscape - l.

The last part of the function name is the abbreviation of the corresponding metric e. There is also a wrapper around every metric in the package to quickly calculate a bunch of metrics:. Important building blocks of the package are exported to help facilitate analysis or the development of new metrics. All of them are implemented with Rcpp and have either memory or performance advantages compared to raster functions.

For more details, see the utility function vignette. One of the major motivations behind landscapemetrics is the idea to provide an open-source code collection of landscape metrics. This includes, besides bug reports, especially the idea to include new metrics and functions. Therefore, in case you want to suggest new metrics or functions and in the best case even contribute code, we warmly welcome to do so!

Overview landscapemetrics is an R package for calculating landscape metrics for categorical landscape patterns in a tidy workflow. Announcement Due to an improved connected-component labelling algorithm landscapemetrics v1. Using landscapemetrics The resolution of a raster cell has to be in meters , as the package converts units internally and returns results in either meters, square meters or hectares.

Utility functions landscapemetrics further provides several visualization functions, e. Contributing One of the major motivations behind landscapemetrics is the idea to provide an open-source code collection of landscape metrics. References McGarigal, K.
