First of all...,

Thank 感謝 2006

FOSS4G
3


Open Source progress...

1985 1995 2001 2006 2009

4


But

How about Data ?
(vector data)

5


still used...

ex. census

updated per 5 / 10 years
cover only paticular areas
on a macro scale
6


Input doesn’t change.
Output doesn’t change, too.

GIS

INPUT OUTPUT
7


If input changes,
output also changes.

GIS

INPUT OUTPUT
8


So why
Data availability and usage
also should be progressed!

ADENDA TODAY

What’s MGD?

Why MGD?

MGD Forum has set up!

What output can be found using MGD?

Concept of my activity

Hands on tomorrow!


What’s Microgeodata(MGD) ?
Vector data before aggregated to mesh and other scale
In other words, Big Geo Data

ZENRIN Map Existing data
Telephone directories
Digital Road Map(DRM)

Probe data
POS data
Customer data

etc 11


What’s Microgeodata(MGD) ?
Hardly found the research using MGD...

Main difficult reasons for usage:
complicated... free!
easy!
ZENRIN Map
simple!
Telephone directories
Digital Road Map(DRM)
very expensive...
Probe data
POS data
Customer data
privacy problem...
etc 12


You can apply and download the part of data
mentioned above! (only for researchers)

Why MGD ?

complicated...

very expensive... free!
easy!
privacy problem... simple!
14


MGD is important for a mature
society and a rapid changing society.

15


Japan faces the largest population
transition in Japanese history.

birth rate
from Wikipedia
excessive population
& concentration and
spreading
16


Japan has many aging and
depopulation areas...

OpenStreetMap(OSM) for analysis
very attractive, but still remain many problems for analysis usage...


OpenStreetMap(OSM) for analysis
日本におけるOSMの学術コミュニティを目指す。
As Mark Iliffe is planning an academic group for OSM,
we will also challenge and join the OSM usage.

Concept of my activity

都市空間の医療ツールとしてのGIS
GIS Analyst as a doctor for urban space

34


In the ﬁeld of medicine, data for
treatment is recorded.

Text
Body Heat

Blood

Heart tones
Blood pressure
35


A doctor examines a patient
based on his/her data

Blood

Blood Pressure

Body Heat

Heart tones

etc...

36


A GIS analyst examines and conveys
a current spatial condition.

owner MGD
for owner
scale route history

traffic volume

for decision-makers population
density

total sale

for citizen etc...
scale

citizen Without a GIS analyst,
who convey to them? 37


MGD can be

the important information
to make a map for future.

38


Conclusion

Although MGD is less commonly
available than FOSS4G,
Very powerful for detailed data analysis.

MGD Forum challenges to promote
micro scale data availability and share
handling knowledge.
