Abstract
The Itatiaia National Park is the first of Brazil Conservation Unit and is part of the Atlantic Forest and the Mosaic of the Serra da Mantiqueira Protected Areas. The objective is the development of a land cover map by GEographic Objects-Based Image Analysis - GEOBIA using the open source software InterIMAGE. The methodology used a AVNIR-2/ALOS image and Digital Elevation Model - DEM and performed the classification through two projects jointly prepared. The classes were identified as aid of a semantic network that used operators based Normalized Difference Vegetation Index - NDVI; Baatz and region growing segmenters. The results were observed through the construction of a confusion matrix that indicated the kappa index of 0.76; the overall accuracy of 79% and; the accuracy index for class that showed differences in results between 68.4% and 100%, showing a diversity of responses for each class. The general classification had good results and is suitable for application in other protected areas in order to provide a basis for control and monitoring of these protected areas.
