Spatial Modeling

• Addressing the map changing problem.

• Define the time spatial database.

• Integrated Modeling and Spatial data.

• Open Formats

• Open Modeling *Engineering the World

• OGC and OPEN MI partnership.


Spatial Enabled Services Hype

• EU INSPIRE Directive.

• EEA Distributed Database Mapping Services.

• Spatial Metadata Categorization. Geo-Semantics.

• Science Commons and Free Access *Research Groups to use spatial

data for data mining *Grid and Cloud enabled Computing

• US ”National GIS” and Open GIS Data *Debate under the Obama Administration

• Industry Marketing. *Focused Geo-Marketing, location aware applications

• Open Accessed Public Data and Geodata.


Spatial Database Competition


Spatial Software EcoSystem


Geospatial Standards Zoology

• Catalog Service (CAT)

• GML in JPEG 2000

• KML (KML)

• Sensor Model Language (SensorML)

• Sensor Planning Service (SPS)

• Styled Layer Descriptor (SLD)

• Symbology Encoding (Symbol)

• Transducer Markup Language (TML)

• Web Coverage Service (WCS)

• Web Feature Service (WFS)

• Web Map Context (WMC)

• Web Map Service (WMS)

• Web Service Common (WSC)

Map Changing Problem

• Cadastral Across Europe

• Land Use Maps

• Raster Images Pattern Recognition

• Distributed Databases * data normalization problem and cross domain reference

• Temporal Spatial Databases *EEA time series example

• Manual Georeference *old arc desktop clicking days, are not so old after all


OPEN MI

Legacy Modelc, c++, FORTRAN,

DELPHI,MKL

Open MI Experts

OPEN MI Compliant Model

Community Use Cases Diagram


OPEN MI from 50000 ft Above

• State machine *each state represents an object *aspect behavior

• Model Linking. *Mostly Environmental and Water

• SDK under GPL. GUI for Model Linking under BSD.

• .NET and Java Support

• Currently no .NET and Java model Integration.

• GUI editor only for .NET. *Mono Supported ;-)

Future Steps

• Parallel Computing Modeling

• Model Optimization

• Hadoop and Terracotta for RMI model runtime frameworks.

• e-Learning Platform.

• Model Migration

• Grid * maybe a VO
