Armchair Mapping Turkmenistan

Posted by apm-wa on 22 December 2019 in English.

Now that I have been away from Turkmenistan for six months, my efforts at continuing to map that country are by necessity confined to “armchair mapping”, using a combination of Soviet-era military maps that identify municipalities (albeit by Soviet-era names, which often differ from current names), the “Districts in Turkmenistan” list of names of municipalities I posted some time back to the OSM wiki, and the various official name-change documents I also posted to the wiki. It is different from primary data collection on the ground, which I must confess I miss.

Some of the local mappers I trained are continuing to collect and post data, however, so there is some work going on based on local knowledge, and that is a good thing.

A 1916 "New Introductory Geography"

Posted by apm-wa on 16 December 2019 in English. Last updated on 17 December 2019.

During a recent visit to the American Midwest, Ann and I browsed an antique shop where I found a copy of Tarr & McMurry’s 1916 edition of “New Introductory Geography”, a textbook, for five dollars. Since it is long out of copyright I have begun scanning some of the lovely color plates and have posted two of Africa to Wikipedia.

NACIS 2019 Banquet Speech

Posted by apm-wa on 27 November 2019 in English.

My banquet speech at the North American Cartographic Information Society’s annual conference last month was not videographed, but a couple of members asked for recordings, so I used Power Point’s voice recording feature to run through the slides while reading the narrative into a microphone. I then converted the Power Point into an mp4 file using Office 365. The result is not perfect but if you are interested in learning how the mapping exercise in Turkmenistan improved quality of life, you can find the video on YouTube here.

New Dedicated Smartphone, $42.39, Back to Mapillary

Posted by apm-wa on 26 November 2019 in English. Last updated on 4 December 2019.

Today I was in Best Buy looking for something else and saw it was selling the LG Phoenix 4 with 16Gb RAM and Android 7 for $39.99 plus tax (prepaid AT&T but I don’t intend to use airtime). I splurged on it, brought it home, connected to home wifi, installed Mapillary, and on my next road trip will try it as a new dedicated imagery collection device. I cannot really justify spending hundreds of dollars on a GoPro or other pricey dedicated device; my cartography habit has to be kept relatively low cost (I say that having bought a new PC a few years back, the specs of which were calibrated to creating wall maps using Maperitive…)

I also began my first “armchair mapping” of Turkmenistan, working on some imagery collected earlier to update the map, and correcting some errors inserted by novice mappers. I have not yet started a serious examination of the Soviet military maps but that will come.

Since departing Ashgabat, I have not collected much imagery, but anticipating that I will get back into it soon, I decided to invest in a dedicated smart phone just for that purpose–nothing fancy, just something with enough RAM not to crash and able to accommodate a large SD card for storing images. The Mapillary website advises that the requirement for the Mapillary app is Android 4.0 or higher, so I bought a gently used, relatively inexpensive older model Samsung smartphone with Android 4.3. However, Google Play informed me that my newly acquired phone is incompatible with the Mapillary app since it requires Android 6.0 or higher. Google Play refused to install it, so I now have an extra Android smartphone which is essentially useless for the purpose for which I bought it!

Yes, I have pinged Mapillary and asked that its website be updated.

Banquet Speaker at NACIS 2019

Posted by apm-wa on 12 August 2019 in English.

I have been asked to be the banquet speaker at the NACIS 2019 conference in Tacoma, Washington, on October 18th. The topic will be “Open Source Mapping in a Closed Society”, i.e., the cartographic work in Turkmenistan between 2015 and 2019. It is an honor to be asked to speak at the banquet, but I feel compelled to ask fellow mappers who followed my work in Turkmenistan: what points do YOU think I should be sure to cover in my presentation?

The last wall maps I generated of Ashgabat and Turkmenistan took a different turn, due to the heavy data requirements involved in a road atlas of the whole country. I was forced to learn Osmosis and the rudiments of Inkscape to edit SVG files first in order to reduce the volume of data and second to take the Maperitive-generated map and tweak it more easily. The lessons learned are now posted on the OSM wiki here. Comments on this tutorial are welcome.

Working with SVG images has its pros and cons, but on balance I think the map quality is better with this approach. That said, one can only wish that Inkscape and Osmosis were a bit more intuitive!

Back in the United States

Posted by apm-wa on 25 June 2019 in English.

Ann and I have returned to the United States. I am presently uploading the last several thousand Mapillary ground-level images from a series of trips around Turkmenistan made in my final weeks in country. When they are uploaded, that will be it for local imagery collection
:-(

I still have a few loose ends to tie up, including full analysis of geographic name changes, now documented at Turkmenistan Geoname Changes, plus full analysis of the Soviet military maps currently en route to our home in our sea freight from Ashgabat, and of course a fresh writeup of how to generate wall maps using a combination of Osmosis, Maperitive, Inkscape, and Corel Photo Paint. These efforts will compete with the need to effect some urgent repairs to our house, which we have not occupied for 16 years and which our tenants of course rather neglected.

Imagery on the P-1 National Highway, and So On

Posted by apm-wa on 4 June 2019 in English. Last updated on 13 December 2019.

Not quite the last hurrah, but close. With three weeks left in Turkmenistan, Ann and I went to Koneurgench to see the marvelous architectural monuments, to the Dashoguz American Corner to give presentations (mine was on the Apollo 11 moon landing and U.S. space program; Ann’s was on White House chinaware). While moving around, we of course collected geodata and imagery.

We had a couple of spare hours during the return, so we went north up the P-1 highway past Ruhubelent to cover a section never before imaged (I will upload the Mapillary imagery after returning to the United States this month, where the Internet is much faster). The road was horrible! It took an hour and a quarter to go 50 kilometers, and at times we drove on the sand because it was smoother than the broken asphalt. Upon return to Ashgabat I logged into OSM and downgraded the P-1 north of Ruhubelent from trunk road to tertiary road. We identified several villages and other POIs, corrected one mistagged object (it was not a residential area, it was a cotton yard), and so on.

Departing Turkmenistan in June

Posted by apm-wa on 24 May 2019 in English.

After almost four and a half years in Turkmenistan, Ann and I will depart in June upon completion of my tour of duty as U.S. ambassador here. My successor was confirmed by the U.S. Senate this week and so I must depart to make room for him. Since we started mapping Turkmenistan, we have posted over half a million ground-level images on Mapillary, over 280,000 edits, created these wiki articles:

Ahal Province Ashgabat Anew Balkan Province Balkanabat Dashoguz Dashoguz Province Districts in Turkmenistan
Gazetteer of Ashgabat Street Names Lebap Province Mary (Turkmenistan) Mary Province Turkmenabat
Turkmenbashy Turkmenistan Geoname Changes Tag:office=diplomatic,

and expanded the Turkmenistan wiki article to approximately 10,000 words. We have dug up authoritative lists of all municipalities in Turkmenistan, created from scratch a gazetteer of street names in Ashgabat, and added over 11 thousand roads and streets.

Alas, our contributions will mostly come to an end with our departure, but I hope that people I have trained over the past four years will continue to contribute to the Turkmenistan map in OSM.

Turkmenistan Geoname Changes

Posted by apm-wa on 5 May 2019 in English.

I have started a new wiki page to document changes to geographic names in Turkmenistan from 1992 forward. Since geographic names are established by the central government by decree or parliamentary resolution, there has to be an official document attesting to each change. My current intent is to collect as much information on name changes between 1992 and the present as possible, then to maintain the page into the future. With a lot of help from some friends in Ashgabat the page is started. There are still citations of government decrees and resolutions missing but with luck and more time perhaps we can find them, too. As time permits I hope to upload copies of the relevant decrees and resolutions for reference.

Last week I spent four days on the road, speaking at the American Corner in Turkmenabat, meeting with local businessmen, and visiting Hojambaz out of curiosity–it is an out-of-the-way city, and I adhere to the philosophy that you cannot know a country by sitting in the capital. You have to get out and see as much of the country as possible if you want to understand it.

Of course, during the trip I collected geodata while going from appointment to appointment. Several villages got identified from ground truth, we found a few new gas stations, collected some street names in populated areas, and perhaps most important, I ran down some minor anomalies on the map of Turkmenabat, which is Turkmenistan’s second-largest city. A couple of major streets’ names were misspelled, and that has now been corrected based on ground truth. A dead end was discovered and mapped in a section of town that previously had been better connected. Errors in nomenclature of major POIs were corrected (e.g., the Lebap Province Library is not the “city library”). Along the way I collected over 28,000 Mapillary images, which are now being uploaded.

We took the P-39 highway to Hojambaz. Between the China National Petroleum Company’s camp at kilometer 21 and the connector to the Amu Darya bridge it is horrible. We traversed 200 kilometers in six hours, for an average speed of 33 kph. We worried about the return, as another six hours would have us driving in the dark, but locals advised us to take “the Chinese highway” (“Hitaý ýoly” in Turkmen), which CNPC built a few years ago but which we had never heard of. With the help of directions from locals, we found it, and discovered a smooth ribbon of asphalt that took us to the 21-kilometer signpost within a couple of hours. That route is now on OSM, too.

The sun had set by the time we returned to Turkmenabat, and the Silk Road Monument was lit up. Click here to see what it looked like!

A friend got me a set of Soviet military maps dating to the 1970s and 1980s, which are uncopyrighted and unlike Soviet military maps of foreign countries contain original cartographic data and are not based on stolen copyrighted materials from foreign sources. I have thus begun examining them when the weather is bad for usable data. Two new route numbers emerged, the P-3 and P-10 national highways, which have been duly added to both the map and the Turkmenistan wiki article. The maps have also helped identify some villages on roads less traveled, where the names were preserved from the Soviet period into the current period (not many, but a few, and every little bit helps).

The map of Turkmenistan is actually useful. Today I needed to buy an elastic bandage, which involved a trip to a pharmacy. We have mapped enough pharmacies in Ashgabat that finding two pharmacies nearby was easy. The bandage was made in Dashoguz, and cost 16 manat (about $4.50 at the official exchange rate).
