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

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

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

AIGID current.

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

processing functions using the

GDAL / OGR

Select Spatial

resource in

CKAN

Select

Processing

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

the QGIS community

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
