Biography

I am a biologist and I hold a PhD in Biological Sciences and an MSc in Remote Sensing and GIS applications. I work as an assistant researcher for CONICET at the Mario Gulich Institute of the Argentinian Space Agency (CONAE) in Córdoba, Argentina. My research is focused on uncovering environmental drivers of vector-borne disease outbreaks. I am mostly interested in those environmental features that can be derived by means of satellite image analysis, remote sensing time series and GIS-based techniques.

I am a strong advocate for OSGeo and free and open source software for geo-spatial (FOSS4G). Moreover, I am part of the GRASS GIS Development team. I have also volunteered as a mentor for GRASS GIS in the Google Code-In contest introducing high school students into the Open Source world.

pymodis, GDAL and GRASS GIS: A FOSS4G example to build time series of MODIS data

Recently, the National Aeronautics and Space Administration (NASA) has re-processed all the MODIS archive and made available the sixth version for all land products. In this post, I share a script that combines different FOSS4G tools to download, mosaic, re-project, subset, import, apply quality assessment flags and build a time series of MODIS LST daily products. First, we use the pymodis tool modis_download to automatically download 4 tiles of the MOD11A1 product for the period 2010-2016.

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.
