The focus was of course QGIS. But to be hones BEAM Visat was a real eye-opener. Yes, I have been introduced to the software while working in an expert group on satellite imagery. We earlier this year concluded a report for the Norwegian Space Centre where BEAM Visat was mentioned as one of several crucial components for handling remote sensing data. But – the workshop provided an applied context which gave me a whole new perspective to both software and methods.
A new set of the Quarter Degree Grid Cell shapefiles has been generated. This time the coverage is global and the publication is for individual countries.
The QDGC shapefiles contain center lon/lat coordinates and the QDGC string for the different squares. The files are offered down to level four. For a country around the equator level four covers around 45 square kilometers with length and height a little under seven kilometres.
The calculations/export this time took around 60 hours computer pricessing time including generation of world fishnet with the different sizes, square area calculations, assigning QDGC strings, compression and more. Continue reading →
For almost ten years now I have been working in the areas environment and development cooperation with geographical Information Systems (GIS) as my foremost tool. My recent postings and tweets about the theme begs for a proper term and a definition. I have chosen development cooperation GIS. For my tweets I will follow up with the twitter hashtag #devcogis.
Looking at the term development cooperation GIS I will point to related policy level work and exemplify the development cooperation GIS by highlighting current projects where it could find its use. I will also briefly present parts of my own work and discuss challenges in development cooperation GIS.
