Approach: First, develop prototype system using prototype test data.　 Next, examine the adequateness and reconsider services (data, GUI, etc) . (to achieve better services with Best Effort )

Sample Dataset is created and adopted:

Time Sequential images - Optical Image : MODIS daily/composite image - Microwave image : AMSR-E Daily Image (descending and ascending are pre-merged into 1 image/day for easy view)

Reference images - Base Map (mosaic of ADEOS-II/GLI) - Base Map (mosaic of JERS-1/SAR) - DEM (Global Map)

Agriculture & Forestry related disaster monitoring Recent Progress : Inundation Monitoring


Use Case: First, the most recent AMSR-E image is pre-selected to see

the current wet area.

Then, user open the thumbnail view window to see the time sequential changes.

User can also change image to base map to see the permanent water body and other circumstances.

Land Information Map Provision system for Local Resident With Chiba Univ.

***


Land Information Map Provision for Local Resident Outline

Target User : Public User (Japanese Local Residents)Target Area : Japan (Test Site : Chiba Prefecture)

Objective : Allow public people to use various land information data resources of

- Satellite image, Governmental Map, General Vector - in the regional scale. to see - local environment and its changes, - potential land vulnerability against flood.

Data : - Satellite Images (Landsat) …… JAXA - Land Condition Maps (1/50,000 scale) …… Chiba Univ.

(Geomorphological Land Classification Map, etc)

Approach: Freeware Based WMS Development


Land Information Map Provision for Local Resident System Overview

< Data on JAXA Server >-Satellite Color Image（ 3 period）-Land Use Map created by satellite data(3 period)-Geomophological Land Classified Map （ Polygon ）-Geomophological Land Classified Map （ Paper Scanned Map ）- GIS Data Pack

＜ Data on CEReS Server ＞- Past Flood Map-Land Condition Maps (Paper Scanned Map)　 (Geomophological Land Map,Soil Map, Land Surface Map etc)- GIS Data Pack - Satellite Color Image

Main Data Resource : Land Condition Maps

・ Map Layer・ Geomophological Land Map Layer

・ Legend・ explain about special terms

・ Satellite Image Layer

Reference Map - view the location - indicate the location

Area selection ：・ BBOX of 1/50,000 maps

Land Information Map Provision for Local Resident User I/F


- Language Labels (place name, etc) put onto the image are shown in Japanese.

- Data type To allow overlay, important geomophological land classes (Low

Lands) are vectorized.

- Area selection To allow smooth area selection, 1/50,000 area selection menu is

added. (Land classes and legends of geomophological land map differs

according to the 1/50,000 map area. )

- Color allocation Color allocation was taken care to differentiate each resource data

(general GIS, geomophological land classified map, land use map, etc),

Land Information Map Provision for Local Resident Key Points to build the system


Land Information Map Provision for Japanese Local Resident Use Case

Public people may;

- View the satellite image (color image/land use map).- Compare the past image to figure out the changed area.- Zoom in the changed area, then overlay the general GIS data

(boundary, road, railroad, place name, etc) to get the place name and guess where and why the changes occurred.

To see local environment and its changes;

To see potential land vulnerability against flood;- View the satellite image (color image/land use map).- Overlay geomophological land classification map (polygon data) , to see location of urban/residential area and potentially vulnerable area to know land condition (potential vulnerability).

- Refer to the legends and terms-explanation to help understanding of the meaning of maps.


Low Lands ＞Blue Polygon － Valley Plain, Delta Plain,

Marshland, etc (potentially vulnerable area)Purple Polygon － Natural Bank, etc

* Distortion of polygon data are under edition.

By overlaying Satellite image and land-class-data;User view the location of

- City Area/Housing Area And- Low Land

To see the potential vulnerable residential area.

Evaluation System evaluation will be implemented in near future by Chiba

Univ.

Expected Achievement

This would be a good test case to proof

- usefulness of WMS to realize local scale web service with easy operation.

- efficiency of providing satellite image and other map resources together for public users.

- application building such as disaster prevention/monitoring field would be feasible and be more expandable in cooperation with external agencies.

Land Information Map Provision for Local Resident Achievement


Land Condition Map Provision for Japanese Local Resident What we learned on Freeware (MU MapServer)

On-the-Fly projection (PROJ.4)

In JAXA/CEReS system, resource data: 3 different projections Tokyo Datum-UTM, JGD2000-UTM, JGD2000-Geographic lat/lon,

output projection : JGD2000- lat/lon

*Tokyo Datum : Former Japanese Datum JGD2000 (Japanese Geodetic Datum 2000) : New Japanese Datum

MU MapServer uses existing free libraries;

PROJ.4 - Coordinate / Projection Converting Library GDAL - Geospatial Data Library OGR - Vector library


What's New in MapServer 4.4.*

WCS support (server only). Support for a time dimension in WMS. Support for internationalization(i18n) encodings in map labels. (Tested with Chinese, Japanese and Thai. )

… Free and Open Source Software has enough function to build a simple test-site.

Support for various data format (GDAL, OGR)

Land Condition Map Provision for Japanese Local Resident What we learned on Freeware (MU MapServer)

In JAXA/CEReS System,

Resources: ERDAS/Imagine, Tiff, shapefile, etc

converted into the single output format automatically (Png).

Gateway System Development for Dispersed Servers,

& Social Application Development With Keio Univ.

***


Gateway System Development for Public users Outline

ObjectiveTo encourage satellite data usage in social and economical field more

widely through the interoperable systems.

Working AreaDevelop gateway system to combine dispersed interoperable servers.

• Apply data set of JAXA and Keio to main WMS.• Connect with dispersed servers.• Develop “data search and view system” (2D, 3D view)

Develop Application system onto the gateway system e.g.

• educational application using “data search and view system” I/F

Coverage Type : WCS1.0.0 targets GRID Coverage only. (most of satellite data would be included in GRID coverage)

- Supporting at least 1 of following encoding is required.- Servers may serve other encoding as well. ａ． GEOTIFF ｂ． HDF-EOS ｃ． DTED ｄ． NITF ｅ． GML

Gateway System Development for Public users New Search & View System BuildingII

Necessity of upgrading

Problem of former system;

- Target data shown in search menus is prefixed. - Searching ability has limited. (e.g. Area search, Date search, Free text search, etc) … more flexible search function is needed. - Overlay function has not equipped. (e.g. overlay of satellite image and vector map)

Creation of Standardized Metadata First, we create JMP2.0 compliant standardized metadata. (JMP2.0; Japan Metadata Profile 2.0; ISO19115 compliant)

IIGateway System Development for Public users Result of Searching “Sumatra” View Window


Achievement- Various type of search ability has been added in the search &

view system.- Seamless viewing ability after searching/finding the target image.- Able to overlay multiple resources on demand.

Items to be considered- Mechanism to find external service entities, and to get/create

metadata of external service would need to be considered.

Others- Collecting all data resources by each individual agencies is less

efficient.- Cooperation with existing framework (e.g. EO Portal) will be

effective way to increase and enrich service data.
