Oracle Spatial

Smallworld Insync Nightly Data Refresh

ESRI SDE Nightly Data Replication

Read/Write Only Spatial Data Repository

Architecture

•  Oracle Spatial 11g •  Glue to make this happen •  Geometry Functions •  Multiple projection support •  Network Model •  SDO_GEOMETRY supported by both ESRI & GE

Smallworld


Architecture •  GE Smallworld Insync

•  Two Way Synchronization •  Customized mapping of data model

•  ESRI SDE •  Database Engine •  Supports Oracle SDO_GEOMETRY

•  ESRI ArcGIS Server •  Server based platform for producing web and

mobile GIS applications •  Produces map and geospatial analysis services •  Supports Map Tile Caching •  Adobe Flex / Microsoft Silverlight / Javascript API’s


Architecture May 2011 Oracle Spatial User Conference

Challenges

•  Not all arc types supported in Oracle Spatial •  Join fields often complex and difficult to model

outside of Smallworld •  Geometry Cleanup needed •  Migration of symbology •  Text Geometries •  Multiple geometry support


Solutions

•  Interpolate unsupported arcs to straight lines. •  Join fields solved by custom Insync mappings. •  Text Geometries exported as point and

appropriate control info added as attributes. •  Symbology created in ESRI ArcGIS. •  Views created for single geometry

representation of tables (assets).

Oracle Network Model

•  Connectivity Data Extracted From Smallworld •  Smallworld uses same concept as Oracle

•  Links & Nodes •  Different Connectivity Models For Each Dataset

•  Data Model Modifications •  Need to bind the assets to connectivity records •  Allow tracing based on attribution

•  Switch Position •  Phase


Oracle Network Model May 2011 Oracle Spatial User Conference

•  Prototyping •  Oracle MapViewer •  Java API •  SQL API

•  Oracle 10g In Memory •  Memory Issues

•  Oracle 11g On Demand •  Whole network traced

•  Web Services •  Adhoc Users •  Integrated into viewer

applications

V I D E O
