The following are slides (in Spanish) from a presentation I gave at FOSS4G+State of the Map Argentina 2017 regarding who is mapping Argentina in OpenStreetMap (OSM). Using the OSM full history extract, I determined that mapping activity in Argentina is stagnating and even declining between 2015-2017. Uruguay is following the same flattening or declining trend, while mapping in Chile continues to increase. Further research is needed to understand how these compare with other local trends around the world.
I also calculate the number of OSM contributors per capita at the department level to show regional patterns of high and low participation. Some areas around Córdoba and Patagonia see higher numbers of contributors than expected, while northern Argentina and some of the southern and western peri-urban regions of greater Buenos Aires show lower numbers of contributors than expected. I use the CrowdLens for OpenStreetMap tool to examine varying levels of activity in four different locations within Argentina.
Overall the most active mappers in Argentina likely have local knowledge and access to the area, as most of them have over 80% of their changesets in this country and use the Spanish language in their changeset comments. Most people who contribute in Argentina do so only one time, however.
