  1. Oracle’s platform for geospatial developers Jayant Sharma, Technical Director, Spatial Oracle USA Inc.

  2. Agenda <Insert Picture Here> • Spatial platform • Its usage • Technology oerview • Database • Middleware • Discussion

  3. Maps, Geocoding, Search

  4. Store and query spatial information SELECT c.holding_company, c.location FROM competitor c, bank b WHERE b.site_id = 1604 ANDSDO_WITHIN_DISTANCE(c.location, b.location, 'distance=2 unit=mile') = 'TRUE'

  5. Store and retrieve geospatial imagery

  6. Store and analyze geospatial networks

  7. Store and manage 3D data

  8. Supports all Geospatial Datatypes Polygons (admin, sales territories, high risk zones) Locations (points of interest) Networks (roads, utilities) Data 3D data type (city models) LIDAR Data Type TIN Data Type Imagery (satellite imagery) Topology (data provider)

  9. <Insert Picture Here> Usage Types: Reports, Search, Analysis

  10. Reports – Crew & Order Locations

  11. Query - View Work Order Now view work orders associated with the highlighted asset features. Slide 10

  12. Analysis - Asset Assessment Scoring Thematic Maps showing analytic information. This represents the current state of the Main Line infrastructure. Slide 17

  13. Spatial Database Services Abstract Data Type ROADS Element 0 P6 P7 RNAME ID TYPE LANES GEOMETRY H4 P8 P5 H3 M40 140 HWY 6 Element 1 (Hole) H1 M25 141 HWY 4 P1 H2 Geometry Data Type P4 P2 P3 Indexing Rtree X Y x1 y1 x2 y2 x3 y3 Query/Analysis Select, join, buffer, within distance, nearest neighbor, intersection, union, convex hull, centroid, ... x4 y4 x5 y5 Access: SQL (Structured Query Language)

  14. Spatial Data in Tables Data type: GEOMETRYRASTER NETWORK TOPOLOGY Road ROAD_ID 1 2 3 NAME Homestead Bellomy Santa Clara SURFACE Asphalt Asphalt Asphalt LANES 4 2 2 LOCATION

  15. Inside 500 meters Spatial Operators • Full range of spatial operators • Implemented as functional extensions in SQL • Spatial Relationship Operators • Inside Contains • Touch Disjoint • Covers Covered By • Equal Overlap Boundary • Distance Operators • Nearest Neighbor • Within Distance Within Distance

  16. Original Union Difference Intersect XOR Buffer Spatial Functions • Database Server Side Spatial Functions • Union, Difference, Intersect, etc. • Spatial Aggregates • Buffer • Point at bearing • To_GML • Geometry Validations • Length • Area • Distance • Etc…

  17. St Thomas 5 miles First Street Royal George Hilton Main Street A Spatial Query Find all nearest hospitals within 5 miles of my hotel SQL> SELECT H.Hospital_name 2> FROM Hospitals R, 3> Hotels H 4> WHERE R.Hospital_type =‘A&E’ 5> AND H.Hotel_name = ‘HILTON’ 6> ANDMDSYS.SDO_WITHIN_DISTANCE( 6> R.Location, H.Location, 7> ‘distance=5’) = ‘TRUE’;

  18. Oracle FMW MapViewer • Map rendering service: Server component • Provides a comprehensive set of APIs: • XML, Java, and AJAX-based • Enables easy development of client viewers • Enterprise solution for management of map content and metadata • Oracle Maps • A map cache server • Caches and serves pre-generated map image tiles for base map layers • A feature of interest (FOI) server • Renders dynamic geospatial features on top of base map layers • An Ajax-based JavaScript mapping client library • Fetches map tiles and FOI from the server • Controls user interaction with maps and dynamic features. • Map Builder • Utility for creating and managing map metadata • Create, modify, delete: Styles (colors, text, line, markers), Themes, Map definitions

  19. Development tools: JDeveloper ADF

  20. JDeveloper ADF

  21. Oracle Application Express

  22. Oracle BI EE Answers

  23. Some Oracle Spatial Partners Geospatial Tool Providers Specialty Systems Integrators Data Providers NAVIGATE

  24. “Spatial is not special” • Location is a CORE element of enterprise data • Location should be openly accessible to the spectrum of platforms (GIS and non-GIS) • Location should be a 1st class citizen of enterprise data management Try to imagine another core data type being managed without the benefits of data management ‘best practices’

  25. Q & Q U E S T I O N S A N S W E R S A
