[HOT] reprojecting EMI datasets (was Nepal: Hospital import gone wrong?)

I was able to reproject the Kathmandu Valley rivers data into WGS84 and
verified it correctly overlays rivers visible in OSM. Let me know how you'd
like me to send the shapefile to Rafael and if I should proceed with the
rest of the EMI data sets. I'm happy to help.

Thanks,
Bernadette
