2013 G8 has announced
the Open Data Charter
Governments of many
countries began
to publish data on the Internet in
response to this charter
https://data.gov.uk/
https://www.data.gov/
The government of Japan also began
to make the data public site
But
Functions, such as to preview the
spatial data in the map in these the
Japanese government of the site was
not implemented
The Japanese government is
promoting a project to utilization of
digital spatial information in parallel
with the open data

Spatial information related project budget of the Japanese government (2013-2020)
An overview of the plan of the government
related to the spatial information
Launch an organization to operate it by creating a foundation
system of spatial information
Construction of Disaster Prevention System
Improve the use of IT in agriculture, forestry and
fisheries
Activate the local activities
To expand the project that uses spatial information technology
abroad
I described in this presentation about the
marked project in the following red rectangle

2014-2015 Ministry of Internal
Affairs and Communications has
developed a system named G space
platform

These groups gave
the system development
work
I did the work of creating
mechanisms to use the spatial
information in a combination of
open source software in this team
These groups gave
the system development
work
This year
Ministry of Land, Infrastructure and
Transport is preparing for the
operation of this system

I am also a member of the AIGID.
I work for publishing this system in

Using CKAN as data catalog
Already extensions for some of the spatial
data has been implemented in CKAN
 ckanext-spatial
 ckanext-geoview
 recline_view
 ckanext-basemaps
change basemap of ckanext-spatial to the maps of
Geospatial Information Authority of Japan
Our prototype system
Functions that we have extended
 Improved the preview function of spatial
resources
 Implementation of the spatial data processing
functions using the GDAL / OGR
 Implementation of the WEB Map to overlay
displaying selected plural spatial resources in
the CKAN
 Made the ability to purchase application by
selecting the spatial data product with private
companies
Improved the preview function of
spatial data
 Debuged WMS preview
 KML, GeoJSON,CZML
 Use GSI map as Background map
Implementation of the spatial data
processing functions using the
GDAL / OGR
Implementation of the spatial data

method
Specify the
parameters for
the processing
Execute
processing
(GDAL/OGR)
stores the result
in the WEB
public directory
of the server
Send the
results of the URL by
e-mail to the user
Users download
files from a
specified URL
Implementation of the WEB Map to
overlay displaying selected plural
spatial resources in the CKAN
Select spatial resources to display
together then open map
Made the ability to purchase
application by selecting the spatial data
product with private companies
 Some of the private companies in Japan
have sold the spatial data. Such as satellite
image, aerial photos, laser measurement
data, car navigation log, and so the
position of the mobile phone log ,they
sold.
 You can find them in our site.You can also
make a purchase application of their data
Made the ability to purchase
application by selecting the spatial data
product with private companies
select the data you want to buy
adds the selected information to the cart
Create estimates
Future plans
 We are working and trying to the public
of the system this year in November.
 It is also a plan to use paid data of the
private sector in this system
 We are trying to implement a preview
and overlay display of data that varies
with time

I am a member of
the QGIS community
I want to a little talk about QGIS
We can use the wonderful plug-in
called CKAN browser in QGIS
We can search for CKAN repository
from QGIS With this plug-in
The spatial data in the search have
been CKAN can be used as a layer of
QGIS
I think QGIS is an excellent tool in
order to use such data repository
Thank you for your attention
