A year ago I had mapped 10,000 sq. miles, or 21.48% of the country and I had around 5,500 military, domestic, economic, and propaganda places marked. It took me around a year to get to that point (remembering of course that I wasn't doing this every single day, and I'm still not always able to work on this).
Today, I've mapped out 26,137 sq. miles (56.15%) of the country (which is 46,541 sq. mi. in size). Of that, 8,219 sq. mi. has been mapped just since the start of 2015. My productivity has greatly increased since I decided to set a completion date: Dec. 31, 2015. And that includes combining my finds with the extensive original work of NKeconomywatch and Google Earth user "Planeman_".
To finish this year, I need to map an avg. of 78 square miles a day. So far, I'm averaging 83. That places me 5 days ahead of schedule right now and puts me on target to finishing 20 days early by year's end. Of course, something could happen and my average rise or fall.
As noted in an earlier update, to help with effective mapping, I divided the country into sections covering (roughly) 25 square miles. This map shows each section that I have mapped. The elevation is set so that each dot is 5 miles in diameter, thus, mostly covering the areas I have fully mapped.

In terms of items marked: 18,657 total items; 3,221 military (inc. DMZ, Airports & Road Blocks), 4,140 monuments, and 11,103 domestic & economic locations. Here are the specific numbers for a few select items: 389 anti-aircraft batteries which represent about 1,900 individual guns, 327 communication/cell towers, 364 electrical substations, and 145 town markets. I've also mapped out hundreds of miles of new roads, main irrigation canals, coastal fences, and border fences.
Included under the "military" heading are, 461 additional places along the DMZ, 140 DMZ related road blocks, and 76 airports, heliports, and aviation test facilities (6 hadn't been located before).
I've also marked all 23 current and former border crossings, twenty of which connect with China. Plus, 159 key mountains & local geographic high points.
Here's a few images to give you an idea of what all I've mapped.
