In March 2021, I taught a GRASS GIS online workshop as part of the distance learning offer of Gulich Institute (CONAE - UNC) in Argentina. We had a total of 65 students from different countries in South America.
During the workshop, we studied different topics within GRASS ecosystem, but we mostly covered remote sensing, Object Based Image Analysis (OBIA) and time series analysis, making use of GRASS GIS extensions to obtain and process Landsat, Sentinel and MODIS data.
Water bodies eutrophication is a worldwide environmental problem characterized by excessive phytoplankton growth which often includes occurrence of harmful algal blooms events. Chlorophyll-a concentration is widely used as an indicator of biomass and …
Dengue fever is one of the most widespread vector-borne diseases in the world. The virus causing it is transmitted by Aedes aegypti mosquitoes. The prevention of virus transmission is mostly based on vector control, with vector surveillance as the …
This study presents the first results of the use of co-clustering to identify potential spatial and temporal concurrences of favourable conditions for the emergence and maintenance of West Nile Virus (WNV) in Greece. We applied the Bregman block …
Temperature time series with high spatial and temporal resolutions are important for several applications. The new MODIS Land Surface Temperature (LST) collection 6 provides numerous improvements compared to collection 5. However, being remotely …
Temperature is one of the main drivers of ecological processes. The availability of temporally and spatially continuous temperature time series is crucial in different research and application fields, such as epidemiology and control of zoonotic …
