Status of

Land Information Map Provision System

(JAXA - Chiba Univ.)

Land in Japan is potentially vulnerable against flood.

- 3/4 of property, - half of population, concentrate in the flood region, which corresponds to only 10% of the country area.

Background of Prototyping- Vulnerability against Flood

* lower area than the river water level at the time of a flood.

Population

Area

Property

Other TypeAlluvial Plain*

Chronic inundation above the floor level occurs in 450 cities/towns.

Knowing potential vulnerability of residential area, prior to disaster occurs, will contribute to mitigate the damage of disaster.

Useful data resources of land condition information are dispersed.

• Administrative thematic maps (geomorphological maps) are useful to estimate vulnerability.

• Satellite images are useful to detect changes..

Land Information Provision system to demonstrate the efficiency of utilizing dispersed spatial data via OGC interface.

Background of prototyping - Necessity to bind dispersed Data

Resources

Achievement with prior prototype

Collaboration with outer organization(data holder), Chiba Univ. Built freeware based dispersed OGC server/clients in JAXA and in Chiba Univ.Use case driven.Adopt old and recent Satellite images, land condition map(geomorphological map), etc. Usefulness of WMS is verified by Chiba Univ.

Potential vulnerability against flood differs even in small region.

Prototype Revisal

ServiceUse can view- EO images (Base map, Flood image) - Non-EO maps (land condition map, land classification map)- Distribution of the point-data (e.g. flood observed point)- Attiribution of the point-data (explanation about land condition, etc)

PurposePrototype development adopting actual flood image

- Attribute of the point are to be viewed by query.

(e.g. land condition category, Explanation of the land condition terminology, (damage information, vulnerability against flood, etc) )

Query function is under building …

Prototype Revisal

Example of Images Comparison

Building area

Valley plain

Natural LeveeLower terraces

Giving multiple information resources allows user to see: - location and range of the flood - potential vulnerability of the land - land class of the flooded area

Items to be considered further

For further development, items below will be considered.

Information Contents　 - Attribute description will be refined to share knowledge about the meaning of the data

User I/F - Show recommended layer combinations in Menu - Functions to compare multiple images easily of the same area (- Gazetteer for easier access)

Feedback comment from Chiba Univ. will be taken into the considerin prototyping.

Project Overview

Themes

Objectives

Early detection in the East Asia bloc on each themes below.

Verify the usefulness of WMS/WFS systems in cooperation with outer Data-Owner/User agency (MAFF).

Hotspot Monitoring in Thailand Hotspot Monitoring in East Asia Vegetation Monitoring in East Asia Inundation Monitoring in Indochina Region.

Snapshot of the prototype Hotspot Monitoring System in East Asia

By setting the target period long, frequently fire occurring zone can be seen.

Observation time can be quickly acquired from client server according to “End Date” via XML.HTTP.

Latest Date is chosen as a default.(in operational phase)

Customization Example :Date/Time Control is equipped based on the user requirement.

Ongoing Activities

Prototype transfer

JAXA provided source code to MAFF on Hotspot Monitoring Systems.

MAFF is now developing operational routine, to build the link with their own NOAA and MODIS ground system.

Milestone

Prototype development (by JAXA)

Vegetation/Inundation Monitoring

Ongoing Activities

Software component replacement

Replacement of software component in the current WMS client system is under planning, in accordance with server renewal. ( Adopt freeware for easy maintenance/customization for prototyping purpose. )

System OS SoftwareServer System Linux Apache,

Perl , IDL (Image processing)

Client System Linux Apache, EarthNavi (Map Applet), GD library PostgreSQL,PHP,

Future enhancement - under discussion
