Once I've completed my own primary mapping project (excluding the irrigation file), I'm also going to integrate what I've done with the published works of two others to create a "master file" which should make available the whole of North Korea with no overlaps and very few, if any, holes. As time permits, I will also release additional files that will give you the locations of any other items I find interesting or that deal with national infrastructure (like town signs, rural schools, etc).

In 2013, vast amounts of Ryanggang Province were covered by low resolution satellite imagery, however, much of that has now been updated to high res. This means that there's a lot of the Province I need to go over (once again) and map, since objects in the low res. areas were nearly impossible to interpret. The Province has a low population density so I'm hoping I can finish it and release the updated KMZ file for it relatively soon.
Until then, my next blog post will be about the incredible untouched wilderness areas of North Korea. So be sure to stay tuned!
