Caracterização sócioambiental do município de Caucaia (Ce) utilizando sistema de informação geográfica (SIG): subsídios para o ordenamento territorial

The municipality of Caucaia, located in the State of Ceara, has been showing a great population growth, resulting in a significant urban expansion accelerated in recent years. In this context, it has developed a Geographic Information System (GIS) with the main objective of realizing the socio-environmental and auxiliary activities related to management and land use. In designing the system, we used orthophotos at scales 1:20,000 (area of the city) and 1:2,000 (urban area of the seat), generating a proposed grouping of cartographic data mapped at the level of detail. From the GIS, one can perform analyzes and queries (spatial or tabular), allowing the visualization of geographic data and optimizing the search of information, contributing in a direct way in making the correct decision on the part of public managers. A point to note is the potential for future system upgrades, and the same dynamic.

USO DO ÍNDICE RDE PARA DETERMINAÇÃO DE ANOMALIAS DE DRENAGEM NO RIO CAPIBARIBE (PE)

O perfil longitudinal de um rio e a representacao cartesiana da relacao entre sua altitude e o seu comprimento. Esta relacao tem sido usada como importante elemento para estudos geomorfologicos e hidrologicos; a exemplo dos estudos para determinacao das anomalias de drenagem. Este trabalho teve como objetivo a determinacao e classificacoes das anomalias de drenagem do Rio Capibaribe (PE). A analise foi feita a partir do perfil longitudinal do Rio Capibaribe, construido com o auxilio do software Google Earth, atraves do indice RDE proposto por Hack (1973). O perfil longitudinal do Rio Capibaribe encontra-se relativamente equilibrado, apresentando ainda anomalias de 2a e 1a ordem. Tal perfil apresentou uma geometria atipica nos trechos entre os quilometros 100 e 150, 150 e 200 e 200 e 250 em decorrencia do aumento das declividades no sentido de montante para jusante, visto que a literatura indica que em um perfil tipico as declividades devem diminuir no sentido da foz.

REMOTE SENSING DATA USE INMONITORING OF DETERIORATION OF VEGETABLE COVERAGE COUN TY GARANHUNS-PE

This research aimed to make a multi-temporal analysis of vegetation cover in the municipality of Garanhuns-PE, in times dating back to 1990, 2000 and 2010, showing the gradual removal of vegetation for pastures and urban expansion, for this analysis was taken as parameters calculations NDVI-(Index Normalized Difference Vegetation) are spectral transformations, resulting remote sensing TM / LANDSAT 5 in ArcGis 10.2.2 computing environment. The NDVI images were classified into four classes, they are: dense vegetation, sparse vegetation, undergrowth and no vegetation, through this classification was possible to quantify the degraded areas of vegetation cover classified as dense vegetation, dense vegetation in 1990 corresponded to an area of 26.9406 Km², and a percentage of 6%, in 2010 the dense vegetation decreased by 6%, getting only 0% of its dense vegetation, corresponding to an area of 2,052 km², the class named as sparse vegetation, had in 1990 an area of 297.9594 Km², corresponding to a percentage of 65%, since the last year of analysis these numbers increase to an area of 355,7592Km², corresponding to 78%.
