| Abstract | This article is committed to evaluate the performance of a semantic network generated by data mining for the classification of land cover using GEographic Object-Based Image Analysis (GEOBIA) in a tropical mountainous area. The study area corresponds to the Nova Friburgo County, with an extension of 933 km², located in the region of the Fluminense Ridge, presenting thus a steep mountainous relief. Based on a visual interpretation of the images, eight land cover classes were defined: rockies, forest, grasslands, sparse grasslands, burn scars, reforestation, shadow, and urban areas. The dataset used for data mining was composed by 130 attributes and by 225 training samples accounting for all land cover classes. The algorithm C4.5, implemented in the software Weka 3.6.4, was employed for the data mining procedure. The following attributes were selected by C4.5: NDVI, fourth principal component, second angular moment, homogeneity, entropy, and slope. The obtained global accuracy was 88%, and the Kappa index reached 0.81. Only the class urban areas presented omission errors greater than 50%, being confused in some cases with sparse grasslands, forest, and burn scars. In view of the obtained value for the Kappa index, we can state that the classification presented an excellent accuracy according to a rating scale specially elaborated for such index. |
