Therefore, it is necessary to map vegetation in urban areas, to assist the planning and implementation of public policies. As a technology presented in the last decades, the so-called Terrestrial Mobile Mapping Systems - TMMS, are capable of providing cost and time effective data acquisition, they are composed primarily by a Navigation System and an Imaging System, both mounted on a rigid platform, attachable to the top ofa ground vehicle. In this context, it is proposed the creation of a low-cost TMMS, which has the feature of imaging in the near-infrared (NIR) where the vegetation is highly discriminable. After the image acquisition step, it becomes necessary for the semantic segmentation of vegetation and non-vegetation. The current state of the art algorithms in semantic segmentation scope are the Convolutional Neural Networks - CNNs. In this study, CNNs were trained and tested, reaching a mean value of 83% for the Intersection Over Union (IoU) indicator. From the results obtained, which demonstrated good performance for the trained neural network, it is possible to concludethat the developed TMMS is suitable to capture data regarding urban vegetation.","PeriodicalId":39973,"journal":{"name":"Anuario do Instituto de Geociencias","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47006878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, hydrographic basin techniques were applied, assessing the vulnerability to the debris flow from geomorphological, geological, climatic, and anthropic aspects, and morphometric parameters relevant to the triggering of these processes in watersheds were calculated. Seven physiographic units were identified, which supported the understanding of geological and geomorphological aspects of the basin: coastal plains; river plains; colluvium and talus ramps; escarpments of Serra do Mar; upland of Paraitinga; mountainous relief and hillocks domain. The sub-basins located in steep sections of the relief, with high slopes, valleys, and channels docked, high drainage densities present higher values in the morphometric parameters, indicating a greater potential for triggering and occurrence of debris-flow processes. The joint analysis of physiographic compartmentalization with the identification of relief features, slope, amplitude, valley, slope shapes and morphometric parameters, is extremely relevant to recognize hydrographic basins susceptible to debris flows, as it integrates, and correlates aspects of the physical environment considered to trigger in the occurrence of these processes.","PeriodicalId":39973,"journal":{"name":"Anuario do Instituto de Geociencias","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48774485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the sandy texture favors vulnerability, and the infiltration and percolation of fluids increase the risk of contamination of the aquifer in the presence of polluting sources. The population’s knowledge about these problems is still ephemeral, which can lead to the consumption of contaminated water, putting health at risk. Thus, research was conducted in the municipality of Russas – Ceará, to study the quality of groundwater, the possible polluting sources in the urban area, and assess the possible risks to human health. First, technical visits for reconnaissance and survey of information were conducted, such as possible polluting sources and situations of existing wells. The selection of wells to collect water followed criteria of proximity to polluting sources, well conditions, and, mainly, those linked to the use of water for human consumption. The result showed that 43% of the samples are above the limits proved by Brazilian legislation for turbidity, total hardness, TDS, sodium, chloride, and nitrate, while the others are withinthe standard. Concerning chlorides and nitrates, the concentrations show there is possibly a relationship with anthropic contaminants(agricultural area; domestic effluents) for the aquifer recharge areas and condition common problems to human health. Therefore, it is of paramount importance to continue research in Medical Geology that will enable the monitoring and future management of water quality of groundwater for the population.","PeriodicalId":39973,"journal":{"name":"Anuario do Instituto de Geociencias","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43315376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Para alcançar tal objetivo, o presente estudo elaborou uma recriação do mito por meio da substituição da onça e do gato-maracajá (os dois animais citados nas variantes) pelo Smilodon populator, animal extinto cuja ocorrência pretérita é bem documentada no Brasil. Além disso, o presente estudo demonstra o potencial de tal metodologia para o ensino da história evolutiva de grupos biológicos, uma vez que se faz presente aqui também um breve resumo sobre a evolução no grupo interno dos Felidae, além de abordar os hábitos de vida do gato-maracajá (Leopardus wiedii) e de Smilodon. Como a história evolutiva de Felidae está intrinsecamente relacionada a ambos os táxons referidos, o método aqui empregado revela um notável potencial para a divulgação e ensino de Geociências e Biologia.","PeriodicalId":39973,"journal":{"name":"Anuario do Instituto de Geociencias","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47653700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
