1. Predicting soybean grain yield using aerial drone images
RESUMO O estudo objetivou avaliar a capacidade de índices de vegetação (IV) obtidos de imagens aéreas por veículo aéreo não tripulado em estimar a produtividade de grãos de soja, nas condições de solo e clima da microrregião de Teresina, Piauí, Brasil. Avaliou-se a cultivar de soja BRS-8980, em estádio R5, submetida a dois regimes hídricos (RH)

2. COMPARING A SINGLE-SENSOR CAMERA WITH A MULTISENSOR CAMERA FOR MONITORING COFFEE CROP USING UNMANNED AERIAL VEHICLES
ABSTRACT There exist two options for digital cameras that can capture the near-infrared (NIR) band. Conventional red–green–blue (RGB, visible bands) cameras with a single sensor provide NIR band visibility based on the removal of the internal NIR-blocking filter. Alternatively, multisensor cameras exist that have a specific sensor for each band. The modi

3. ESTIMATION OF MAIZE BIOMASS USING UNMANNED AERIAL VEHICLES
ABSTRACT Unmanned aerial vehicles (UAVs) are a promising tool for technology development and transfer and for the economic success of the agricultural sector. The objective of this study is to assess the validity of biomass estimation in a commercial maize plantation using aerial images obtained by a UAV. The proposed methodology involved analyzing images ac

4. The transport infraestructure contribution to the urban legacy of the Beijing Olympic Games
Resumo Os Jogos Olímpicos, ao eleger uma cidade como sede, demonstram evidência no cenário global e a concentração de investimentos no local. São realizadas intervenções urbanas que podem acelerar a realização de diretrizes preconcebidas ou redirecionar o processo de planejamento urbano. No entanto, as discussões sobre o legado de grandes eventos

5. Introducción al análisis socio-ecológico a partir del mapeo colectivo del propio territorio: los usos por parte de distintos actores sociales y sus conflictos associados
Abstract: The present article exposes a practice in the course “Ecology and Development” in a school of natural sciences. The objective is to promote the students’ appropriation of the campus space, the socio-environmental conflicts, and the concepts of socio-ecological systems. Through discussion and the use of aerial images, bibliographical informati

6. Determination of the junction angle in fluvial channels from georeferenced aerial images from Google Earth Pro and UAV
Resumo Os ângulos de junção em canais fluviais são determinados a partir de complexos processos de erosão e deposição, resultantes da dinâmica do fluxo da vazão, da morfologia do leito e das margens, das feições hidrogeomorfológicas da bacia, de sua ordem e do uso e da ocupação do solo. Conhecer os valores desses ângulos é importante para mel

7. ESTIMATING VEGETATION VOLUME OF COFFEE CROPS USING IMAGES FROM UNMANNED AERIAL VEHICLES
ABSTRACT Tree crops, such as Arabica coffee (Coffea arabica L.), present enormous technical challenges in terms of pesticide application. The correct deposition and distribution of the active ingredient throughout the aerial part of these plants depends on knowledge of the canopy volume, but manually determining this volume is time consuming and imprecise.

8. PHOTOGRAMMETRIC POINT CLOUD CLASSIFICATION BASED ON GEOMETRIC AND RADIOMETRIC DATA INTEGRATION
Abstract The extraction of information from point cloud is usually done after the application of classification methods based on the geometric characteristics of the objects. However, the classification of photogrammetric point clouds can be carried out using radiometric information combined with geometric information to minimize possible classification issu

9. Design, Fabrication and Flight Demonstration of a Remotely Controlled Airship for Snow Scientists
ABSTRACT: A remotely controlled airship was designed, fabricated and demonstrated within a tight timespan of under a month after receiving the go-ahead. The main design requirement for this airship was to be able to operate from a Helipad located at an altitude of 6,572 feet AMSL under ISA+20 deg.C. The images of the terrain below were recorded during the fl

10. Conception and development of a system used to organize and facilitate access to environmental information
In São Paulo State's ) coastal area, Brazil, for several years, a chemical company discharged, without any sort of environmental control, a blend of industrial waste composed of Persistent Organic Pollutants (POPs). Lawsuits forced the company to identify and limit such deposits in order to perform the environmental recovery. A recovery project was develope

11. Ação de cordia verbenacea sobre schistosoma mansoni / Activity of cordia verbenacea on schistosoma mandoni
The trematode Schistosoma mansoni is responsible for causing a form of schistosomiasis that kills around 280,000 people each year. Since there are cases of tolerance and resistance to the drugs currently used in the treatment for this disease, namely praziquantel (PZQ) and oxamniquine, there is a need for new schistosomicidal drugs. In that regard, the resea

12. Fluxos hídricos na microbacia do córrego do Queixada no município de Jataí / Water flows in the stream watershed queixada in the city of Jataí (Go)
The diagnosis of hydrological flow and the rainfall interception by vegetation is justified by the need for knowing the influence of these elements in river basins, where weeds and appropriate use of land are responsible for maintaining the quality of the slopes, avoiding erosion, soil loss, silting of waterways and induces the maintenance of groundwater res
