What does the future hold
for traditional style mappers?
OSMマッパーの未来は？

What does the future hold for traditional style mappers?

GPS Mapping
OpenStreetMapにおけるGPSマッピングとは

OpenStreetMapは白紙の状態から自分たちで地図を描き始めました。
決して他の地図や情報を写すことなく、
GPSログと使用が許される情報のみで
地図を描きます。

２００７年

Tokyoの書き始めです。

GPSログ

I started OSM in 2008.
There were hardly any maps of Japan and my town then.

These are my GPS Logs of the Fukushima area.

I spent many hours mapping towns on foot and by car using a GPS.

Fukushima,Japan in 2013

Walking a lot and recording a lot of points was necessary
for detailed mapping in Japan.
I did a lot of walking and driving to record these GPS logs.

Tsuruga-jo Castle

in Aizu Wakamatsu, Fukushima

This is Tsuruga-jo castle in Fukushima, Japan.
You may have heard of Tsuruga-jo castle through OSM.

in Aizu Wakamatsu, Fukushima

I spent 6 months mapping this castle using GPS logs
and data I collected on-site.

These are my Tsuruga-jo Logs.

The outer perimeter of Tsuruga-jo Castle is about 2.5km.
I wanted to map it in detail mapping.
On some days I walked up to 23km collecting data from
the outer regions of the castle.

Creating maps from scratch using a GPS takes time and effort
but is very satisfying.


The introduction of Bing images - 2010
OpenStreetMapにおけるBing衛星写真の利用

In November 2010 we heard the big news
that we could use Bing satellite Images for OSM.
I was happy because using the Bing images expanded
mapping possibilities.

Use of Bing images in OSM

Yokomaha City

But at the same time I was sad.
When I realized the amount of information and detail
collected through Bing images.
I could see that maps such as those I created on foot with a GPS
would start to replaced by maps created
using high resolution satellite images.

Use of Bing images in OSM
Many of the maps that I have spent months creating
using GPS logs and logging photos
cannot compete with the information and detail of Bing Images.

Tokyo Station

Tokyo, Kamakura, Yokohama・・・
Many of the places we spent time GPS mapping hold deep memories for us.
But with the advance of tracing using Bing images,
I can see that the maps I created will soon be replaced.

Even so, I'm a mapper!
I was happy to be able to use Bing Images in Japan
and have spent many hours tracing Bing Images,
and thinking about how I could trace best.
I have traced several thousand buildings and roads around Japan.

In 9 months, I traced 16,000 buildings
in central Tokyo using Bing images. Red＝ikiya

But in Japan,
something even more sensational for me was to come.


The introduction of KIBAN - 2012
OpenStreetMapにおける基盤地図情報の利用

KIBAN Chizu Joho
(Fundamental Geospatial Data )
http://wiki.openstreetmap.org/wiki/JA:GSI_KIBAN

http://wiki.openstreetmap.org/wiki/JA:GSI_KIBAN

In 2011, the Geospatial Information Authority of Japan (GSI)
decided to allow people to use the government's mapping data
called Kiban Chizu Joho (KIBAN), on OSM.
This would allow people to trace KIBAN illustrations
but would not allow the importing of data.

This is a sample of Kiban Chizu Joho of GSI data. (1/2,500 scale)

In 2012, it became possible to use KIBAN as an underlay
when editing data on TMS.

http://wiki.openstreetmap.org/wiki/JA:GSI_KIBAN/Using_GSI_KIBAN_WMS

Although KIBAN data is not as new as Bing Images,
it is more accurate and even in its coverage of cities.
Also, with Bing, it is necessary to interpret images
to determine roads or buildings.
However, because this is not necessary with KIBAN.
Map-making has become faster and more accurate.
In 10 months, I traced 70,000 buildings using KIBAN data.

Looking back over my experiences over the last few years, I see this.
Maps created over many months with a GPS have replaced
with more accurate maps created using Bing.
Maps created over many months using Bing images have been replaced
with maps created using even more accurate data.

What do you, as OSM Mappers,
think of this?
To be honest, 'the mapper in me' feel sad.

Yokomaha City

It seems to me that we are moving more towards
open data and open governments.
I for see that even more accurate and detailed data sources
will be used on OSM in the future.
Should this progress be stopped?
今後、OSMへのより精度が高く、詳細なデータの利用は進むでしょう。

Bus stop data collected by riding buses for many months
May be replaced by even more detailed data released
by governments.
The same may be said of Street maps created over many months
using satellite images and GPS mapping.
長い時間をかけてマッピングしたバス停データが
インポートされたデータで置き換わるようなことが
コツコツ衛星写真やGPSでマッピングした地図においても起こるでしょう。


Mappers and Change
マッパーと変化：諸行無常

I have spent many hours thinking about this,
But as permission to use the data has been given,
I cannot find a reason not to use this
more detailed and accurate data.
長い間、マッパーとしてこのことについて考えてきました。

Underlying this is my opinion that OSM should not be
a community just for mappers
- it should be a community for all people.
Even if long hours have been spent creating a map,
if a better map is produced, it should be the one used.
Oosu coast, Fukushima

As mappers who come into direct contact with mapping data,
our roles and presence will changes as OSM grows
and its environment changes.

The driving force behind OSM is the community and people,
and I hope it always will be.
OpenStreetMapのフォースはコミュニティであり人である。
このことは今までも、そして今後も変わらないと思います。

The role of Mappers is to link OSM and people going about their daily lives.
If you look around, you will see that as mappers,
there are still many things we can do.
As for me,
I will continue to map with GPS and Bing trace and KIBAN trace as always.
試行錯誤する中で、今後も私はGPS、衛星写真、基盤地図情報・・・を使って
OSMマッピングを続けるでしょう。
一連の思いに答えが見えた最近です。

答えは「先人を越えて:地図」でした。来年のOSMカンファレンステーマなるかも？

Thank you for listening to
the ramblings of a mapper !
