Radical Tools• Available in the labs• I’ve also posted a link so you can install on

your machine – not for commercial use• Excel Add-in

– Includes• Zip code look up• Zip code to City, State• 3-digit zip to Zip• Road distance between Zips• Find the closest point in a set of Zips• Find the cheapest (in terms of LTL rates) point• Rate LTL shipments• Rate Parcel shipments

Also works with Databases

Intro To GIS

• Useful Tool: GIS

• Geographic Information System– Links databases and maps– Useful for addressing questions like:

• Where should we …?

• How far away are…?

• How are …. distributed?

GIS

• Spatial data– Location – Stored in a shape file, geodatabase, …

• Attribute data– Associated characteristics– Stored in DB

• GIS systems typically maintain these separately and “join” them for display or analysis

Geographic Data

• Raster model– Area covered by a grid of square cells– Image data is a Raster model, cells = pixels

• Vector model – Features represented as

• Points or nodes

• Lines or arcs

• Areas or polygons

Geographic Data

• Key Properties of Geo Data– Projection: The method of translating locations on

the 3-D earth to (X,Y) coordinates on a map or screen

– Scale: The ratio between distance on a map to the equivalent distance on earth

– Accuracy• Positional: Is it in the right place?

• Consistency: Is it correctly categorized?

• Completeness: Is it all there?

– Resolution: e.g., pixel size

Layers

• Different geo data maintained in different data layers with common location information,

Raster Layer: Digital Ortho photo: combines the visual properties of a photograph with the positional accuracy of a map, in computer readable form.

Vector Layer:Lines defining the street network

Vector Layer:Polygons describing land parcels

Smart MapDifferent layers linked by common locations

Software Tools

• ESRI – ArcView, ArcGIS and others

• MapInfo – MapInfo and others

• MS – MapPoint (Tutorial, etc)

• Many others

Geocoding

• Geocoding: – Placing data with location information on the map

• LatLong

• Street Address

• Examples: – Geocode Stores by ZIP (OurCompany.xls)

– Geocode Census Data by ZIP (US Census , Data.gov and private vendors sell demographic data)

Bank Failures

Thematic Maps

• Thematic Maps: – Display the attributes of geographic data

• Examples: – Population

• Sized Circles

• Shaded Regions

– Median Household Income• Shaded Regions

Geographic Queries

• SQL-type query based on geographic information: – Eg. Average household income within 20

miles of Store # 1

• MapPoint is quite poor at this• The 2011 version can do crude selections• Example:

– Household income within 20 miles of Store #1

Distance Calculations

• As the crow flies– Using the Measure Distance Tool

• Over the road– Using the Route Tool

• Add Store #2 as Start• Add Store #1 as End• Get Directions• Over the road distance• Can adjust route options for speeds, hours of

driving, rest stops, …

Territories

• Given fixed centers develop territories based on proximity to those centers

• MapPoint is very poor at this– Either you import them or you build them

by hand…– Other (more expensive) packages do this

automatically

Programming Tools

• MapPoint includes software links (COM or Component Object Model) that allow you to integrate MapPoint into your applications (e.g. with VB, into Excel, Access, …)

• We won’t go that far. • Interested: See

About Programming with MapPoint• Embed within Excel, etc.
