I have the last week or so started to import IBGE data for municipality borders of Espírito Santo state. I think this is the last state to do this kind of import. I have had a few problems doing the import, firstly I spent a lot of time finding out how to extract the data from the shapefile. The problem was that since I have no computer of my own, and have limits of what I can install on work computers, I was not able to get any convertion tools running (such as ogr2ogr, shp2osm, etc) and couldn't find any plugins to JOSM allowing to open the shapefile. But than I got the idea of trying out Merkartor, which are available in a portable version I can run from my portable hard drive. It allows me to open the shape file and do tracings directly from there.

The problem that I still am facing is:
1) Merkartor doesn't allow me to save for some reason, might be a bug in the latest portable version. This results in that I have to upload changes for each edit session.
2) Since I run from a portable disk, long edit sessions can end in a crash, like today, when I loose all data not already synced.
3) Since I am not familiar with Merkartor, I tend to find the program complicated, and want to return to JOSM as soon as I have completed this import. I also return to JOSM at times to clean or fix data.
4) Unstable internet connection from work. The internet line here is imbarresingly slow, and at times completely non-existing. In worst case I will not be able to upload an edit session, and a whole day work might get lost because of no connection errors for too long.

Despite all of this, I have already imported more than half of the borders, all state border municipalities completed, just missing a few coastal municipalities, and filling in the gap in the middle. I will complete it all by (in JOSM that is) adding relations for Micro and Mesa regions as well as Grande Vitoria metropolitan area. The map will look better when all of this is done. I'll probably make links to all relations checkers from the state wiki page.
