4. Geospatial 101
• Mapping Solutions
• Your data vs. mapping data
• Lat / Long vs. Polygon
• Uses and Advantages
• Address Normalization

5. Geospatial 101
Mapping Solutions – SaaS Solutions
Google Maps
• http://maps.google.com/
• MapsGL
Bing Maps
• http://www.bing.com/maps/
Google Earth
• KML File

6. Geospatial 101
Mapping Solutions – Spatial, Premise and SaaS
Oracle Spatial vs. Locator
Navtec, ESRI, etc. data in your own DB
Oracle ApEx Has Built-in Mapping
Other Hosted Solutions
• Open Street Integraph
• Virtual Earth Natural Earth
• ESRI Maps for Free

7. Geospatial 101
Your data vs. mapping data
Your Data
• Customers
• Properties / Homes
• Inventory
Mapping Data
• Maps – Google, etc.
• Shape Files
• In / Nearest

8. Geospatial 101
Lat / Long vs. Polygon
Lat / Long
• Point on the map
Polygon/Shape
• Group of points
• Shape File
• Shapes
• Metadata
Can measure “in” for
polygons or “nearest” for
points

9. Geospatial 101
Uses and Advantages
Why Use? Using it to your
• Glitzy / Sexy / Looks good advantage
• Intelligence about your • Directions, Other
customers, your data, “Similar”
etc. items, Connecting things
• Nearby Gas
Stations, Railroad
tracks, Boundaries

10. Geospatial 101
Address Normalization and Geocoding an Address
Address Normalization
• Zip+4
• http://www.semaphorecorp.com/cgi/zp4.html
• CorrectAddress
• http://www1.intelligentsearch.com/address-verification/correct-
address.htm
• Google API
Geocoding an Address
• Google Geocoding API
• https://developers.google.com/maps/documentation/geocoding/
• Web Service APIs

11. Hopefully something will spark ideas for you!

12. How Have I Used Geospatial Data
IntelliReal
• Considerable geo data, knowledge, etc.
TUSC
• Embedded into several apps at TUSC (ACT)
Independent Nation
• Political mapping solution
InteliVideo
• Where are people connecting from?

13. Heat Maps
A look at different neighborhood trends in home values

14. GeoSearch
Visual Slice and Dice – home type, bedrooms, bathrooms, price

15. Highlight and Visual Search
Find all homes that sold in this area for 20% less than their “value”

16. Test Scores within a radius
ACT scores
By Zip Code
Google API supports
– Heat Maps
• Outlines
• Polygons
– Circles
– Overlays
– Events

17. With Google Maps or Yahoo or…

18. Mapping Your Data
Do you have data in your Oracle database that
you would like to visually map?
All you really need is a lat and long (or an
address)
Easy integration Starts At:
• https://developers.google.com/maps/
Simple Pushpins:

19. Hello World Page
Static HTML page
Copied HTML from
Google page and
pasted here

20. Dynamic Generation
Data driven mapping
Properties in
Arapahoe County, CO
PL/SQL region with
onload function

21. True AJAX Mapping
Mapping that pulls
data dynamically
from an XML page
Lat / Long are
passed to XML page

22. Change the Icons
Any image

23. Add a Popup Windows on Click
Any information
can popup

24. Yahoo Pipes
http://pipes.yahoo.com

25. Yahoo API -YQL
Free Data and APIs from Yahoo
• http://developer.yahoo.com/yql/console/
Local Events
• select * from upcoming.events where woeid in (select woeid from geo.places where
text="North Beach")
Local Places
• select * from local.search where zip='94085' and query='pizza'

27. Neighborhood Comp Boundaries
Create boundaries for a property
• Using roads, water features (lakes, rivers), landmarks (parks), military
bases and rail roads
Created a function to return this info
• Input is lat/long, but we can change to prop id once we have parcels
loaded up
• Other inputs – big roads (Y/N), distance (miles from property – 1), min
distance (0), min length (.1 miles), band (1=1st, 2=2nd, etc.)
Get_Kml is in the notes…
• Will produce a KML file for Google Earth viewing

28. Boundary Example 1
Major streets
Lakes
Parks
Major features
Square vs. Polygon

29. Boundary Example 2
Powerful Boundaries

30. Tons of Free Data!
Tiger
• http://www.census.gov/geo/www/tiger/shp.html
• US Government Project – US Census
UK Census Data
• www.census.ac.uk/casweb
Open Street Maps
• http://www.openstreetmap.org/
• Open Source Collection Group
• It’s free! Maps are more detailed than Google too!

31. Getting OpenStreetMap Data
“Shape Files”
OpenStreetMap by State
• http://osmdata.thinkgeo.com/openstreetmap-data/north-america/us/

32. Map Features
Tiger
• http://www.census.gov/geo/www/tiger/tgrshp2012/documentation.html
• www.census.ac.uk/casweb - UK census data
OpenStreetMaps
• http://wiki.openstreetmap.org/wiki/Map_Features
Features
• Addresses, Landmarks (Point and Area), Water (Area and Linear),
MSAs, Railways, Military Installations, Tab Blocks (Block Groups,
Blocks), Census Tracts, County, State
Shape Files
• Points and Polygons
• Data (e.g. Road Name, Type)

33. Point to Point Comparison
Nearest “In” or “At”
Area Water (lake) State
Linear Water (river) County
MSA
Area Landmark (park)
City
Area Point (hospital)
Census Tract
Schools
Block Group
Military Installation
Block
Railroad Latitude, Longitude
Address Range

34. Loading Data Visually using Oracle
MapBuilder
Download at
http://www.oracle.com/technetwork/middleware/mapviewer/downloads/index.htm
l java –jar MapBuilder.jar
Import Shapefile

35. Loading Shape Files in Batch
Load Shape to Spatial Data Option (SDO)
http://download.oracle.com/otn/other/spatial/shp2sdo.zip
Creates file structure
If you have multiple files – run the creation only once and create the
spatial index, load the data…
• shp2sdo.exe Tiger DataADDRFEAT tl_2011_01001_addrfeat
