GEOSPATIAL PERSONAL AD

About Me

Name: Parcel Fabric

Status: Single – but can be split and consolidated. Very structured but can change on you at the drop of a dime.

Descripton: Slim outline with distinct identifier. Not very attractive by itself but has a lot of internal qualities that are not shown in the map.

Looking For: Possible relationship with other data to complement slim figure. Easily found using address / name based searching.

GEOSPATIAL PERSONAL AD

About Me

Name: Ortho Image

Status: Single – Requires a lot of time and preparation to get ready. Not a cheap date!

Descripton: Very attractive full colour image – with WOW factor. Provides a lot of context but is not easily found without relationship with other data.

Looking For: Relationship with other data to ‘find myself’. Looking for new markets to show off my ’20cm’ resolution!

When Parcel meets Ortho …

Relationship Build

• Need to find users• Need to have application• Need to maintain autonomy• Need to maintain image of

‘togetherness’ but really live separate lives.

The Results – Zoom2It Plus

Agenda

• GeoWarehouse Online Overview• Application Integration?• Managing the Partnership• Ortho Image – Technology Update

• Web application (www.geowarehouse.ca)• Provides access to Ownership information to

over 4 million properties in POLARIS.• Title Data contained in the GeoWarehouse

database is updated every 10 business days• Map Data is updated daily• Currently – 40,000 registered users

Demo: www.geowarehouse.ca

How it Works

HTTP request• Security• Time• User Information• PIN

Benefits of this approach

• Simple – HTTP request• We use the PIN as the common link to pass back

and forth between applications• Applications and Data are separate

• Less need to coordinate upgrades/ changes to applications

• User’s don’t know it is a different website / server

Lessons Learned

• Integration – applications should not be reliant on other side being available.

• All applications change – try to put together an environment which upgrades can be done independently

• Introduction of new content to the ‘spatially challenged’ should use the KISS principle

• Always remember the target audience• Nothing beats having ‘good people’ to work with

The Results – Win-Win-Win

Summary & Keys to Success

• Fair distribution of risk, responsibility and reward• Solve the business issues then write the legal agreements

with good lawyers• Ensure all parties have necessary resources to work

toward the goals• Be sensitive to differing agendas• Develop win-win solutions• Maintain good governance through open communications

The Results – Win-Win-Win

First Base Solutions• Utilize GeoWarehouse functionality to locate – (Address / Owner Name)• Access to new user base resulting in new revenues• No need to establish market presence – it already existed

Teranet• Extended service offering to users• Interactive Map Viewer with Ortho imagery• Additional subscription revenue

GeoWarehouse Users• Access to aerial imagery integrated with sales and parcel data• Ability to navigate between maps and ownership information• Ability to purchase imagery and parcel

Parcel Processing for Zoom2it

the basic property report• Add additional information• Create a spatial index for speed• Update shapefiles on each web cluster
