Roberto Ribeiro

I work as a GIS analyst for federal transportation infrastructure. In my day-to-day work I mainly deal with spatial data acquisition and quality assurance, database modelling and administration, and photogrammetric processing of aerial and orbital images, though I occasionally also work with GNSS positioning and spatial analysis.

I mainly work with Python, GDAL, QGIS and photogrammetric software (ERDAS, PCI, etc.), though occasionally also C++/CGAL and ArcGIS.
