Mapeo del riesgo: Prioridades para prevenir el establecimiento de tamariscos invasores

Early detection and rapid intervention are among the preferred actions to achieve successful results in the management plans for invasive alien species. The identification of areas where probabilities of establishment and invasion by an alien species …

How to aggregate daily data into MODIS-like 8 day aggregation pattern?

Several MODIS products come in “8-day” compositions. Suppose we have daily data and we want to aggregate it with this MODIS-like granularity. How can we achieve that? First idea would be to use the great t.rast.aggregate module in GRASS GIS with granularity=“8 days”. But this presents a problem. It does not re-start every year, but aggregates the whole series with 8-day granularity, not considering the year. Meanwhile, MODIS 8-day products re-start the aggregation every January 1st.

Potential of remote sensing to predict species invasions: A modelling perspective

Understanding the causes and effects of species invasions is a priority in ecology and conservation biology. One of the crucial steps in evaluating the impact of invasive species is to map changes in their actual and potential distribution and …

Estimating Hantavirus Risk in Southern Argentina: A GIS-based Approach Combining Human Cases and Host Distribution

We use a Species Distribution Modeling (SDM) approach along with Geographic Information Systems (GIS) techniques to examine the potential distribution of hantavirus pulmonary syndrome (HPS) caused by Andes virus (ANDV) in southern Argentina and, more …
