Uso de fotografias digitais no mapeamento florestal

With the advent of the new technologies in the area of the remote sensing, the survey of the natural resources started if to use of sophisticated techniques that aim at a more adequate mapping in terms of representative and necessary information of the phenomena and superficial objects, allowing to study the dynamics, to lead, to handling adequately and to monitor. The use of digital photographic pictures is very promising, beyond the easy acquisition supplies important information on changes in the use of the land. The digital cameras, possess potential and application in the monitoring of the natural features. They also present the advantage in the reduction of costs due not to need the process revelation and magnifying because it excuses to the use of the film and scanering of the photograph and, makes possible that the result is seen in the monitor of the computer, besides presenting resolution better. This work has as objective to present a quarrel on the acquired digital photograph use from digital cameras high resolution in the mapping of the forest features.Com o advento das novas tecnologias na área do Sensoriamento Remoto, o levantamento dos recursos naturais passou a se utilizar de sofisticadas técnicas que visem um mapeamento mais adequado em termos de informações precisas representativas dos fenômenos e objetos superficiais, permitindo estudar a dinâmica, conduzir, manejar e monitorar adequadamente. O uso de imagens fotográficas digitais é muito promissor, além da fácil aquisição fornecem importantes sobre mudanças no uso da terra. As câmaras fotográficas digitais, possuem potencial e aplicação no monitoramento dos recursos naturais. Apresentam também a vantagem na diminuição de custos devido não necessitar o processo de revelação e ampliação porque dispensa o uso do filme e escaneamento da fotografia e, possibilita que o resultado seja visto no monitor do computador, além de apresentarem melhor resolução espacial. Este trabalho tem como objetivo apresentar uma discussão sobre o uso de fotografias digitais adquiridas a partir de câmaras fotográficas digitais de alta resolução espacial no mapeamento dos recursos florestais

Stellar Astrophysics and Exoplanet Science with the Maunakea Spectroscopic Explorer (MSE)

The Maunakea Spectroscopic Explorer (MSE) is a planned 11.25-m aperture facility with a 1.5 square degree field of view that will be fully dedicated to multi-object spectroscopy. A rebirth of the 3.6m Canada-France-Hawaii Telescope on Maunakea, MSE will use 4332 fibers operating at three different resolving powers (R ~ 2500, 6000, 40000) across a wavelength range of 0.36-1.8mum, with dynamical fiber positioning that allows fibers to match the exposure times of individual objects. MSE will enable spectroscopic surveys with unprecedented scale and sensitivity by collecting millions of spectra per year down to limiting magnitudes of g ~ 20-24 mag, with a nominal velocity precision of ~100 m/s in high-resolution mode. This white paper describes science cases for stellar astrophysics and exoplanet science using MSE, including the discovery and atmospheric characterization of exoplanets and substellar objects, stellar physics with star clusters, asteroseismology of solar-like oscillators and opacity-driven pulsators, studies of stellar rotation, activity, and multiplicity, as well as the chemical characterization of AGB and extremely metal-poor stars.Comment: 31 pages, 11 figures; To appear as a chapter for the Detailed Science Case of the Maunakea Spectroscopic Explore

VISTA Variables in the <i>Vía Láctea</i> (VVV): Halfway Status and Results

The VISTA Variables in the Vía Láctea (VVV) survey is one of six near-infrared ESO public surveys, and is now in its fourth year of observing. Although far from being complete, the VVV survey has already delivered many results, some directly connected to the intended science goals (detection of variable stars, microlensing events, new star clusters), others concerning more exotic objects, e.g., novae. Now, at the end of the fourth observing period, and comprising roughly 50% of the proposed observations, the status of the survey, as well some of results based on the VVV data, are presented.Facultad de Ciencias Astronómicas y Geofísica

The Detailed Science Case for the Maunakea Spectroscopic Explorer, 2019 edition

(Abridged) The Maunakea Spectroscopic Explorer (MSE) is an end-to-end science platform for the design, execution and scientific exploitation of spectroscopic surveys. It will unveil the composition and dynamics of the faint Universe and impact nearly every field of astrophysics across all spatial scales, from individual stars to the largest scale structures in the Universe. Major pillars in the science program for MSE include (i) the ultimate Gaia follow-up facility for understanding the chemistry and dynamics of the distant Milky Way, including the outer disk and faint stellar halo at high spectral resolution (ii) galaxy formation and evolution at cosmic noon, via the type of revolutionary surveys that have occurred in the nearby Universe, but now conducted at the peak of the star formation history of the Universe (iii) derivation of the mass of the neutrino and insights into inflationary physics through a cosmological redshift survey that probes a large volume of the Universe with a high galaxy density. MSE is positioned to become a critical hub in the emerging international network of front-line astronomical facilities, with scientific capabilities that naturally complement and extend the scientific power of Gaia, the Large Synoptic Survey Telescope, the Square Kilometer Array, Euclid, WFIRST, the 30m telescopes and many more
