1. Identification of sugar cane fields in the state of sao paulo using a time series of AVHRR/NOAA satellite images.
Brazil is the first world producer of sugar cane. Despite the economic and social importance of agribusiness to Brazil, it is still difficult to estimate the harvest of the its main agricultural crops with the precision and anticipation needed, justifying the study and development of new methods based on the use of remote sensing data, for example. Even cons

3. Monitoring sugar cane crops through dtw-based method for similarity search in NDVI time series.
Brazil is an important sugar cane producer, which is the main resource for ethanol production, a renewable source of energy. Due to the strategical importance of this agricultural commodity, it is necessary to improve models that assist the crops monitoring process. Recently, remote sensing images have also been used to crops monitoring. Vegetation index ima

5. Relação entre a resposta espectral da cana-de-açucar, registrada nas imagens dos satelites AVHRR/NOAA, em São Paulo, e dados agroclimaticos, no periodo de 2001 a 2008 / Relationship between the spectral response of sugar cane, estimated through images of AVHRR/NOAA satellites, in the state São Paulo, and agroclimatic data, from 2001 to 2008
O Brasil, maior produtor de cana-de-açúcar do mundo, conta com uma posição privilegiada para atender as necessidades mundiais de açúcar e álcool anidro. O país possui regiões produtoras, sendo o estado de São Paulo a maior delas, com safras alternadas que podem garantir a presença do produto nos mercados local e mundial. Isto requer, cada vez mais

7. Utilização de perfis multi-temporais do NDVI/AVHRR no acompanhamento da safra de soja no oeste do Parana / Use of NDVI/AVHRR time-series profiles for soybean crop monitoring in the west of Parana, Brazil
Crop yield forecasting systems are important sources of information for helping Governrnent and private institutions in agricultural trade matters. The traditional methods of crop yield forecasting norma1ly do not provide precise estimations, due to its subjectivity. The use of Geothecnology has been studied for the development of more efficient crop yield f

8. Evaluation of EOS/MODIS and NOAA/AVHRR sensors in the detection and reporting of fires and burnings / Avaliação dos sensores EOS/MODIS e NOAA/AVHRR na detecção e registro de incêndios e queimadas
The efficiency of detection and monitoring of fire forests is fundamental for fire control and reduction of costs and damages in firefighting operations. Therefore the need for efficient methods for forest fire detection, allowing a faster action and better decision-making. Remote sensing can be a suitable tool for preventing and fighting forest fires. The o

9. Aplicação de logica fuzzy para estimativa de area plantada da cultura de soja utilizando imagens AVHRR-NOAA / Application of fuzzy logic for soybean crop area estimation using AVHRR-NOAA images
An early accurate estimation of agricultural crop areas, such as soybean, is fundamental for the Brazilian economy. The draining forecast and the estimation of agricultural production commercialization are strategic to Brazil, since they are directly related to planning, costs and price. Recent technological progress of data acquisition from orbital remote s

11. Outgoing longwave radiation at the top of the atmosphere: preliminary assessment using GOES-8 imager data
Radiâncias obtidas do satélite GOES 8 nos canais de vapor d'água e infravermelho termal (2, 4 e 5) foram utilizadas para estimar Radiação de Onda Longa (ROL) emergente no topo da atmosfera. As estimativas de ROL pelo utilitário ITPP5, aplicadas à informação do sensor HIRS/NOAA, foram consideradas como "verdade de referência". Imagens dos dois saté

12. Processamento de imagens AVHRR/NOAA visando o monitoramento de estiagem
A great part of the Brazilian territory is vulnerable to the occurrence of frequent intense dry periods since there is a difference between the precipitation and the annual potential evaporation during the year. Some methods have been proposed to assess and monitor the occurrence of a drought, such as that ones based on agroclimatic indexes calculated with g
