“Spatial” Tables

• Just like regular tables

• Contain a column of type SDO_GEOMETRY to store

the geometric shape of the objects

CREATE TABLE map_countries (id NUMBER PRIMARY KEY,

id NUMBER PRIMARY KEY,name VARCHAR2(30),geometry SDO_GEOMETRY);

Oracle Fusion Middleware MapViewer

• A J2EE component (.ear) for developing web mapping applications.

Usually deployed in WLS.

• Renders geospatial content stored in an Oracle database.

Background maps can be from 3rd party providers.

• Provides Java, Javascript, and XML request/response APIs.

Mapviewer facilitates different options

• For content

– Local (Oracle database)

– Online web services

– Hybrid (local database + online content)

• For development

12

• For development

– Java or javascript code embedded in application

– Using ADF Faces (<dvt:map>)

Mashup methods

and examples

13

Basic Mashup: Application Content and MapViewer

• Simplest form: a database query containing a spatial

column, aka a MapViewer theme

• Or the result of a stored procedure which

• Can be spatial (e.g. asset location) or non-spatial

(e.g. work orders)

14

(e.g. work orders)

• Must have a location identifier (e.g. asset id)

• Or contain the location

MapViewer renders database and map content

stored in a local database

MapViewer enables custom map styles

18

External Services and MapViewer

• Can be spatial (e.g. weather) or non-spatial (e.g. BI

report)

• Must have a location identifier (e.g. county name, or

region id)

• Or contain the location (e.g. georss)

20

• Or contain the location (e.g. georss)

• Can be an XML document (BI report, georss) or

JSON or embeddable content (e.g. media)

• Or an OGC WebFeatureService 1.0 response (i.e. a

GML 2.11 feature)

Display Content (XML) from External Services

25

External Map Services and MapViewer

• Built-in support for Google and Bing Maps

– Purely for tiles not their full javascript API

• Interface (MVCustomTileLayer) for accessing other

online map services (e.g. ESRI or OpenStreetMap)

• OGC WebMapService and WebFeatureService

26

• OGC WebMapService and WebFeatureService

interfaces are also supported

MapViewer also renders application content on

background maps from online services

Summary

• MapViewer displays application content on maps

• The content can be in an Oracle database, or

• Can come from other platforms or services

– Such as OBIEE or web services like Weatherbug

• The map data can be stored using Spatial, or

31

• The map data can be stored using Spatial, or

• The background maps can come from services

– E.g. Bing or Google Maps
