Automatic Organization of Coordinate Systems

1. Automatic Organization of Coordinate Systems Automatically organize coordinate systems and scales depending on the kind of media Pixel Coordinate System Arial Photo-image Server (KOKUSAI) Detail Map Server (Oki Electric) Vector Coordinate System

2. The Open GIS Specification Model Topic 12: The Open GIS Service Architecture Geospatial Coordinate Transformation Services (GCTS) Transform geographic coordinate values from one coordinate system to another

3. Physical Compensation of Geospatial Object Automatic Compensation of Spatial Object Distortions which happens in composing multiple objects Example of distortions between building-outlines of the residential map and the city planning map They are compensated and symbolized in order to adopt thematic maps. Application DB Server (NEC) Detail Map Server (Oki Electric)

4. Physical Compensation of Geospatial Object Automatic Compensation of Spatial Object Distortions which happens in composing multiple objects Example of distortions between building outlines of the summarized-map and the thematic map. Summarized map does not hold building-outlines, so their locations are not only compensated but also symbolized. Application DB Server (NEC) Summarized Map Server (PASCO)

5. The Open GIS Specification Model Topic 12: The Open GIS Service Architecture Feature Analysis Services (FAS) Exploit information available in a Feature or Feature Collection to derive application-oriented quantitative results that are not available from the raw data itself. Composed of 9 operations ①Buffering to create a proximity zone ②Boolean operations to perform binary operations on two or more features ③Determine if any features in the Feature Collection obstruct ④Compute non-stored geometric properties ⑤Exploiting elevation coverages ⑥Create geospatial model of one or more related Feature Collections ⑦Interpret feature properties ⑧Exploiting transportation routes ⑨Computing exposure

6. The Open GIS Specification Model Topic 12: The Open GIS Service Architecture Geospatial Feature Manipulation Services (GFMS) Support creation, quality control methods, analysis, and display of feature collections of interest to an end user. Composed of 5 operations ①Register one feature to another、an image, or another data set or coordinate set. ②Examines the internal correctness and consistency of features and their properties ③Deconflict features by applying ④Modify a feature and its description ⑤Modify the values of metadata elements (properties) describing a feature

7. District. Town Tall Road General Road Railroad Water Part Railway Station Buildings Government office Buildings Annotations Semantic Compensation of Geospatial Object Compensate the difference between objects which hold a same name but hold different entities. Compensate difference caused from the M-to-N relationships of objects. Application DB (Disaster Prevention) Legacy DB1 ( Residential Map ) Legacy DB2 ( Summarized Map ) City Bound. Town Bound.

10. Process flow of GSM’s active retrieval mechanism (in future) WWW Server GSM Active Retrieval Mechanism Evaluate Terminal Capability Data Blade or Data Cartridge Dispatch Spatial Retrieval Func. Image Conversion Media Conversion ORDBMS Vector Conversion Uniquely managed Spatial and Attribute Data Feature Conversion If the terminal capability is sent to the GSM, it is evaluated and dispatched spatial retrieval functions, then retrieved data is actively converted into various forms by the media conversion function. This mechanism corresponds with various level of portrayal model.
