Interface to the birdwatching datasets at proyectoavis.com
Interface to the proyectoavis.com bird observations records
database. It provides means to download datasets filtered by speces, order,
family, and several other criteria. Provides also basic functionality to
plot exploratory maps of the datasets.

Implementing the BDAT tree taper Fortran routines, which were
developed for the German National Forest Inventory (NFI), to calculate
diameters, volume, assortments, double bark thickness and biomass for
different tree species based on tree characteristics and sorting information.

Provides four boolean matrix factorization (BMF) methods.
BMF has many applications like data mining and categorical data
analysis. BMF is also known as boolean matrix decomposition (BMD)
and was found to be an NP-hard (non-deterministic polynomial-time)
problem. Currently implemented methods are
