Mar10, 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

Mar10, 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. Agriculture & Forestry related disaster monitoring Recent Progress : Inundation Monitoring

Mar10, 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

Mar10, 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

Mar10, 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.

Mar10, 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. :Low Lands Land Information Map Provision for Local Resident Overlaying Low Lands onto Satellite image :Artificial Area :Upland and Terraces

Mar10, Land Use Map in 2001 Turned to Housing Area, Along with JR train line. By overlaying GIS data onto Land Use Map; User identifies actual place name and circumstances of interested area. Land Use Map in 1987 Water body Paddy Forest Grassland/Cropland Bare soil Urban/Industrial area Housing area Land Information Map Provision for Local Resident Viewing local environment and its changes Turned to Housing Area, Along with Keisei-Chihara train line.

Mar10, 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.

Mar10, Gateway System Development for Public users New Search & View System Building II 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)

Mar10, 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.
