Slippymaps andOracle Spatial


Who We Are – What We Do

• Where2GetIt – leading provider of productand store locators• We help consumers find our clients products either

online or offline• Web and IVR• Over 450 Brands (Olive Garden, Office Depot,

Sony, Viewsonic, Outback Steakhouse, ColumbiaSportswear, etc)


Sample client


What does Oracle Spatial dofor Where2GetIt?

• Provides• Address level Geocoding

• Driving Directions

• Reverse Geocoding


Our Implementation

• Already a current Navteq client• Use both NA and WE data sets

• Loading process

• Infrastructure

• Use in Slippymaps.com & legacy apps


Loading Process

• Converted Navteq shapefiles to Oracle tables• Wrote conversion utility – 10x faster than shp2sdo

• Extract data from Oracle tables into schemaspecific models for Geocoder and Router• Wrote SQL scripts w/help from Dev team

• Wrote additional SQL to optimize process

• Future – transportable tablespaces fromNavteq


Infrastructure• 2 – OC4J servers running geocoder and

routing engines• 2 – 10G Enterprises database servers with

Oracle Spatial extension• Each OC4J server uses its own database

server• OC4J servers – 16G RAM – Opteron 244• 10G DB servers – 8G RAM – Opteron 244• openSuSE 10.2


Infrastructure

OC4J Server 10G Database

W2GI App Cluster


OC4J Servers

• Ran siege tests to determine load capacity• Geocoding

• Routing

• Optimized OC4J environment

• Determined 16G was optimal configuration tokeep maximum # of partitions in RAM

• Thank you Chuck for your assistance


Geocoding Siege Results


Routing Siege Results


OC4J Servers

• Configuration parameters - Geocoder

<parameters cache_admin="false"

cache_postcode="true"

fuzzy_string_distance="70"

fuzzy_leading_char_match="4"

debug_level="0"/>


OC4J Servers

• Configuration parameters – Router• All route requests are pre-gecoded

<init-param>

<param-name>partition_cache_size_limit</param-name>

<param-value>2048</param-value>

</init-param>


OC4J Servers

• Server startup

java -server -Xms14000m -Xmx14000m

-Dsun.rmi.dgc.server.gcInterval=1200000

-Dsun.rmi.dgc.client.gcInterval=1200000


OC4J Servers

• Numerous Parser Profile changes for US• 3% improvement in address matching

Oracle Spatial API

<geocode_request vendor="elocation"> <address_list> <input_location id="27010"> <input_address match_mode=“default"> <us_form2 street="500 oracle pky" city="redwood

city" state="ca"/> </input_address> </input_location> </address_list></geocode_request>


W2GI API

• Mimicked Spatial API

• Enhanced for our use and integration with ourproducts


W2GI API – Example XML<request>

<appkey>17F2494F-4B9A-3A7D-8D08-2B38D1132AB6</appkey><formdata id="geocoder">

W2GI API

• This approach allows just about any internetconnected application or device to make ageospatial call.

• Just plain old HTTP Get


W2GI Search API

• Combine Batch Route requests with spatialquery

• Able to do proximity search by drive time ordrive distance (market differentiator)


Batch Route Request Example<batch_route_request id="8" route_preference="shortest" road_preference="highway" return_driving_directions="false" distance_unit="mile" time_unit="minute"> <start_location> <input_location id="1" longitude="-71.06901807362172" latitude="42.35157803334855"

W2GI APIs



W2GI API use inSlippymap.com

• AJAX platform

• AJAX calls make URI encoded API call

• W2GI javascript libraries update web pagewith result XML


Slippymap.com

• Using Openlayers & Prototype libraries forcore mapping and AJAX functions

• Added W2GI libraries to provide locatorfunctionality

• Would like to see Oracle Mapserver AJAXlibrary integrated into Openlayers
