Working with GRASS-7.0 and homebrew python on OS X

Sometimes getting all the software you need for Scientific analysis updated and running smoothly in OS X can be a bit annoying. For most things, there’s Homebrew (a nice post on setting your Mac for Scientific analysis with Python and homebrew is this one.) And if you’re into GIS, you probably know William Kyngesburye’s QGIS and GRASS packages. Michael Barton also provides GRASS packages, including the last stable version (7.0.2 at this moment). All seems good, but I started to have some problems because I wanted to have my Python stuff (Numpy, Scipy, Matplotlib, etc) updated via homebrew (to keep system python untouched) and then I tried to compile GRASS and QGIS with homebrew as well, but that didn’t worked out so well. The osgeo4mac formulas for ‘brewing’ QGIS are still for version 2.8 (the last stable is 2.12) and there is a ‘tap’ for GRASS 7, but despite compiling ok, I couldn’t get 3D viewing to work. Eventually I managed to get all working. This is how:

resample and derive or derive and resample? [paper review]

Working with Digital Elevation Models (DEMs) have became a standard practice in scientific disciplines related to the physical environment, from geomorphology, geology, to biogeography and climate modeling. The Shuttle Radar Topography Mission (SRTM - Farr et al., 2007) and ASTER GDEM (Tachikawa et al., 2011) provide a near-global to global coverage at medium spatial resolution (30 to 90m) free of charge, while WorldDEM (Krieger et al., 2009) is a global dataset with 12m resolution and ALOS World3D (Tadono et al., 2014) delivers a global DEM with only 5m resolution.

Curso de Espeleo Resgate - Mambaí, GO

Entre 06 e 13 de setembro deste ano (2015, caso você esteja lendo do futuro) ocorreu mais uma edição do Curso de Formação em Espeleo Resgate, em parceira com o Espeleo Socorro Francês SSF - Spéléo Secours Français. O curso foi organizado (e muito bem organizado) pelos nossos amigos do EGB Espeleo Grupo de Brasília.

Expedição Serra do Aracá 2015

Durante 15 dias em julho/2015 o Grupo Bambuí de Pesquisas Espeleológicas (GBPE) em conjunto com o La Venta Esplorazioni Geografiche organizaram uma expedição de exploração espeleológica/geográfica na Serra do Aracá, norte do Estado do Amazonas. A equipe contou com cinco brasileiros e quatro italianos:

O que é um Invited Review?

Ultimamente recebemos no Brazilian Journal of Geology (BJGEO) alguns pedidos de autores interessados em enviar artigos de revisão, os “Invited Reviews”. Mas o que é esse tipo de artigo? Uma revisão bibliográfica de tese pode ser publicada dessa maneira? Vamos ver:

UTM 23S??

If there’s one thing that I see all the time as a reviewer, is a map of some study area in Brazil with a caption like “UTM coordinates zone 23S”.

FAQ about BJGEO

The Brazilian Journal of Geology is the official publication of the Brazilian Geological Society. As the Deputy Editor, I receive emails with common questions about the journal. So I decided to crate a page with some useful information for potential authors.
