O Parque Estadual do Tainhas abrange ambientes de ocorrência porífero Oncosclera jewelli. Nosso objetivo é indicar as áreas potencial da espécie a partir fatores relacionados à assinatura geomorfométrica dos pontos ao longo Rio no e sua zona amortecimento. Foram realizados cruzamentos análises dados construção manipulação um banco geográficos, nos SIGs SPRING-5.4.3 QGIS-2.18, contendo: a) MDEs ...

A procedure to achieve the semi-automatic relative image normalization of multitemporal remote images of an agricultural scene called ARIN was developed using the following procedures: 1) defining the same parcel of selected vegetative pseudo-invariant features (VPIFs) in each multitemporal image; 2) extracting data concerning the VPIF spectral bands from each image; 3) calculating the correcti...

Becoming successful in fighting forest fires is not only a matter of taking the required measures into consideration and efficiently and economically using the resources, but also employing the cutting edge science and technology in every aspect of the process. Determining the potential fire prone regions within forest stands, plays an important role in the success rate of forest fire preventio...

The northernmost and most arid mangrove ecosystem of West Africa is found in Mauritania, in the Parc National du Banc d’Arguin (PNBA). The existing global and regional maps of Mauritania’s mangroves have little detail, and available estimates of the mangrove area differ among studies. We assessed the use of automated Remote Sensing classification techniques to calculate the extent and map the d...

The spatial distribution of crop and non-crop habitats over segmented agricultural landscapes could be used as a means to reduce insect pest populations. Seven land cover categories such as wheat, rapeseed, vegetable, water, built-up, paved road, and unsurfaced road were extracted from GeoEye satellite images dating from late May to late June of 2010. Three diversity metrics and three evenness ...

The analysis of refugee and IDP (internally displaced persons) camps from VHSR (very high spatial resolution) satellite imagery can assist humanitarian relief organisations by providing population estimations and camp structure analysis based on automated dwelling extraction. Since smooth transferability of rulesets in a fine scale and high complexity environment is limited, we present an appro...

Illegal excavations represent one of the main risks which affect the archaeological heritage all over the world. They cause a massive loss of artefacts but also, and above all, a loss of the cultural context, which makes the subsequent interpretation of archaeological remains very difficult. Remote sensing offers a suitable chance to quantify and analyze this phenomenon, especially in those cou...
