Oracle Exadata Extreme Performance for Spa8al Workloads

•  Oracle Spatial is architected to exploit the processing power, bandwidth, and parallelism of the Exadata Database Machine

•  Only Oracle Spatial is part of the Oracle Database kernel

•  Spatial operations can be performed in up to 2 Terabytes of Database System Global Area memory


Agenda



SPATIAL ENGINE


Spatial on Exadata

21

• We achieve performance improvements based on the exploitation of the processing power, bandwidth, and parallelism of the Exadata machine

•  Parallel query and partitioning help improve Spatial performance

•  Speedups of up to 100 times (compared to a 1-core CPU box) for the typical SDO_ANYINTERACT spatial query

•  Spatial predicates are not currently pushed into the Exadata storage nodes


Fast Coordinate System Transformations

22

•  SDO_CS.Transform is upto 10 times faster in 11gR2 –  This speedup is seen if 1000s of transformations are done in a

session –  This is typical for mapping applications where themes are

transformed at run time to match the base map SRID

•  In the prior releases, the transformation context was created for each transform() call –  now we use that context between transform() calls with the same

source and traget SRIDs

•  This computes a polygon that represents the area occupied by a set of points in the plane

•  Input geometry should be a 2D Geometry of any type –  This is typically a multipoint geometry

•  A concavehull is returned which is guaranteed to be a valid polygon (gtype 2003)

•  Very useful for generating trade areas from a given set of points of interest (e.g., customers)

•  This is different from convexhull

Concave Hull


Convex Hull vs Concave Hull


Transparent support for TTS

25

• Cross-Endian support for TTS and Spatial Index •  SDO_UTIL.PREPARE_FOR_TTS Deprecated

– When spatial data is transported as TTS, there is no need to do any special processing for Spatial indexes

–  This applies to any TTS export done with 11gR2 database

•  SDO_UTIL. INITIALIZE_INDEXES_FOR_TTS now automatically fixes the index if the TTS export is done in a different endian format than the target format


SQLDEVELOPER


SQL Developer Support for Spatial

•  Support for Spatial Data Management – Metadata creation –  Index creation – Validating the Spatial data – MapViewer metadata support

•  Support for Spatial Data Querying – Query results can be viewed graphically


Spatial Data Querying: Single Value •  Spatial shapes can be graphically viewed


Spatial data querying: Map View Display

•  Secondary queries are overlaid

Here we show the counties in California over the States layer


NETWORK DATA MODEL


Oracle Spatial Network Data Model •  An open data model to store and analyze network data. •  Network analyses include:

•  Shortest path •  Nearest neighbor •  Within cost •  Minimum cost spanning tree •  Traveling salesman problem •  Reachable/Reaching nodes •  K-shortest paths


Partitioned Networks •  Smaller partition boundaries in denser portions of the

network (urban areas). •  The number of nodes in each partition is still balanced. •  Load partitions

as needed

NDM Customization -  Network constraints

- Trucking restrictions - Turn restrictions - Avoid toll road - Avoid/use Highway

-  Multiple Cost calculators - Travel distance - Travel time - Local/Highway/Scenic Drive preference - Penalty of road under construction/traffic congestion

-  Goal nodes - Restaurants within 10 min’s drive


Multiple Cost Support in Path Analysis

•  Path/Subpath analysis now supports multiple costs in a single analysis

•  First cost is the one NDM optimizes •  Second cost can be returned as an accumulated

value •  Examples

– Shortest distance paths with travel time –  Fastest paths with travel distance


Hierarchical A* shortest path Analysis

•  Support A* shortest path algorithm •  Provide user defined heuristic cost function •  Support hierarchical shortest path analysis •  Better performance than Dijkstra Algorithm as less

number of nodes are explored – Uses much less memory than Dijkstra


Traveling Sales Man (TSP) Analysis

• Minimum cost tour that includes all given nodes •  Support Points on Network as nodes to be visited • Node visit order can be enforced using network

constraints •  This is useful scheduling problems where a service

representative has to visit a number of customers


Drive Time Polygon Generation

•  A spatial representation (polygon) based on minimum cost network coverage

• Concavehull polygon or convexhull polygon (accuracy and performance)

•  Example – Compute Drive Time Polygon (with travel time as link cost) from

a service station – Use the polygon to determine if a given address can be reached

within a given time using point in polygon operation


Routing with Traffic Patterns •  Fastest Routes are based on speed limits

–  Not very accurate during rush hours – A good non-rush route can be the worst rush route!

•  Traffic Patterns are historical traffic speeds on roads – Can be further classified as speeds on Mon-Thur. Fri. Sat. Sun.

holidays, and special events at 15 min, 30 min, 60 min intervals.

• Need to add temporal dimension (start time) in routing with traffic patterns


Routing with Traffic Patterns • Model Traffic Patterns as user data in NDM

– Neutral traffic pattern metadata and schema – Generate traffic pattern user data automatically – Currently Support NavTeq Traffic Patterns

•  Link Cost is now a time-dependent function returning actual travel time – Start time determines which set of traffic pattern

•  (M-T,Fri.Sat. Sun. Holidays) –  Link distance/Link speed limit (for non-covered links) – Actual Speeds from traffic patterns (interval in a day) – Actual Travel Time = Link Distance/Actual Speed

SDO_GEOMETRY •  Points, Lines •  Simple Surfaces

–  All points of a surface lie in a 3D plane

•  Composite surfaces –  Has one or more connected simple surfaces –  Simple surfaces cannot cross

•  Simple Solids –  Composed of closed surfaces –  Can have interior surfaces

•  Composite Solids –  Consists of n connected simple solids –  Representation might be easier

•  Multi-points, -lines, -surfaces, -solids –  Multi-solid is different from composite solid

GEORASTER


GeoRaster •  A data type to store raster data

– Satellite images, remote sensing data, digital elevation models

– An XML schema to store Metadata

•  Functionality –  storage and indexing of raster data – Generate resolution pyramid –  query and analysis –  delivery to external consumers

•  Publish as JPEG, GIFF images


ETL tool – the GDAL GeoRaster Driver

• GDAL is the best open source geospatial ETL tool/API for raster data –  natively supports import/export to/from SDO_GEORASTER and

many formats including GeoTIFF, JPEG2000, ECW, NITF, HDF, NetCDF, ERDAS IMG, USGS DEM, SPOT.

– C/C++, Java, Python API for accessing GeoRaster – many tools. Two of the important ones are:

• gdal_translate – utility to translate raster formats to/from GeoRaster objects

• gdalinfo – utility to view information about a raster, such as a GeoRaster object


Georeferencing Using GCP •  Georeferencing is the process of mapping pixels on the image to

ground coordinates •  GCP: stands for Ground Control Points •  GCP Model: GeoRaster supports a generic GCP model. In the

current release, 2D cell coordinates, 2D and 3D model coordinates are supported.

•  GCP Storage: GeoRaster defines a GCP XML schema and can (optionally) store GCP natively in the metadata of GeoRaster objects.

•  GCP Manipulation: GeoRaster provides a set of update and query functions to manipulate GCP’s and related data


The GeoRaster Java API

•  Sample Applications: using this Java API, users can easily develop simple applications, particularly web-based applications. GeoRaster viewer is a simple application built with this API.

Tools.java Viewer.java Loader.java Exporter.java


The GeoRaster Java API •  The GeoRaster JAVA API

–  oracle.spatial.georaster: Map SDO_GEORASTER object type to Java objects, support for the core GeoRaster features

–  oracle.spatial.georaster.sql: Java wrapper of the GeoRaster PL/SQL API for some server-side operations

–  oracle.spatial.georaster.image: For generating Java images from a GeoRaster object and for processing the images

•  The image package is based on Java 2D and JAI –  users can leverage all advanced capabilities of Java 2D and JAI

for developing web or image processing applications


•  SDO_GEOR.reproject: transform from one projection to another •  All oracle spatial coordinate systems are supported •  Five re-sampling methods are supported •  NN, Bilinear, Cubic, Avarage4 and Average16.

•  Supports two options •  Reproject persistently: reproject a GeoRaster object and store the

result as a new GeoRaster. •  Reproject on-the-fly: equivalent to getRasterSubset except the

window-based cropping result is transformed into a different projection. The result is stored as a single BLOB.
