CoverType prediction

Predicting forest cover type from cartographic variables only.

Authors: Andrea Somma, Lorenzo Paggetta, Pietro Marelli

The present work showcases different methods to develop a classifier for the Cover Type dataset, in order to achieve an accurate and balanced model for the cover forest type from the cartographic variables in the dataset. The Cover Type dataset contains trees observation from four wilderness areas of the Roosevelt National forest in Colorado. The data is made of cartographic variables only, with no remotely sensed data. It is a rather large dataset, made of 7 forest cover types, more than half a million instances and 54 features, which include data such as elevation, aspect, slope, distance to hydrology, soil type and many others.
