R.mdig.outliers

r.mdig.outliers is a module that detects outlier populations that are apart from the rest.

Currently being implemented...

This can be done using a combination of:

• r.clump (which gives each contiguous area a unique category); and
• r.stats (calculates the area for each category).

We can then use a masked r.clump output map to return only the contiguous populations that are less then a certain area. An additional consideration might be the relative distance from larger clumps, so that outliers that are very close to the main population are not included.

Parameters

• minimum and maximum area for detection as outlier.
