Overview

About

Maintained by Silverio Vilchez-LopezFirst published 2024-11-033 releasesCRAN page ↗

Thematic quality indices are provided to facilitate the evaluation and quality control of geospatial data products (e.g. thematic maps, remote sensing classifications, etc.). The indices offered are based on the so-called confusion matrix. This matrix is constructed by comparing the assigned classes or attributes of a set of pairs of positions or objects in the product and the ground truth. In this package it is considered that the classes of the ground truth correspond to the columns and that the classes of the product to be valued correspond to the rows. The package offers two object classes with their methods: 'ConfMatrix' (Confusion matrix) and 'QCCS' (Quality Control Columns Set). The 'ConfMatrix' class of objects offers more than 20 methods based on the confusion matrix. The 'QCCS' class of objects offers a different perspective in which the ground truth is considered to allow the values of the column marginals to be fixed, see Ariza López et al. (2019) doi:10.3390/app9204240 and Canran Liu et al. (2007) doi:10.1016/j.rse.2006.10.010 for more details. The package was created with 'R6'.
