Populated anthromes: from exploratory analysis of demographic data to mapping

Abstract

This research, developed in R software, sought to analyze Brazilian population data as a source for the construction of regional mapping of anthropogenic biomes, with an eye to its application in national territorial management. Following the guidelines of global mapping of anthromes, the stages of exploratory analysis, mining, merging and plotting of census data were carried out to recognize and identify relevant characteristics of population groups for the construction of the mapping of Brazilian populated anthromes. Sequentially, static and interactive mappings were constructed to verify the spatialization of census information in the maps. In addition, validation and uncertainty studies of the mappings were produced to confirm the quality of the products generated in this research. Given the results obtained, it was found that the regional mapping of populated anthromes significantly approximated the population information to the local reality, compared to the global mapping of terrestrial anthromes. It was also found that the data source analyzed provided sufficient information for the distribution of the population in the mapping of populated anthromes, characterizing and specializing it according to the original data. Furthermore, the statistical analyses proved that the modeling used in this investigation generated relevant results that ensured the quality of the mapping. Thus, it was proven that the data used and the modeling were suitable for future use in constructing the regional mapping of Brazilian anthromes. In addition, an analytical format was established that can be replicated in different territorial contexts that aim to apply anthrome modeling in territorial management.
