Project Initiation: 2009

•  Why a Web Platform? •  Geokov Overview •  Geokov Map Maker •  Data Formats •  Data Providers •  Sharing & Collaboration •  Users

Outline

•  No platform (operating system & hardware) dependence can access the application from anywhere with an internet connection and web browser

•  Access to remote databases as well as real-time data facilitates efficient data and information dissemination, integration, and sharing

•  No need for specialized GIS software application, database upgrades and debugging are done from a central location

•  A user-friendly interface with only the essential tools / functionality no interaction with complex GIS software

•  Facilitates communication and collaboration

Why an online platform?

Geokov A Data Consumer

Strives to:

•  Make data readily available to the end user •  Add value to the data

Data Formats

•  Web Map Service, KML Nework Link, GeoRss –  Suitable for dynamic data –  Less maintenance –  No access to raw data –  Dependent on the provider for availability

•  XML (KML, GPX), Shapefile and other GIS file formats –  Data conversion needed for GIS file formats –  Data currency issue –  Data size issue –  Control over data presentation / manipulation –  Useful for the user with GIS knowledge

Dynamic Data – KML Network Link e.g. Earthquake, Fire, Streamflow, Weather

Web Map Service (WMS) – Changing Data

Web Map Service (WMS) – Static Data

Web Map Service (WMS) – Static Data

KML (Static Data)

Power of Mashup

•  GeoBase •  GeoConnections •  Government of Yukon •  Nova Scotia •  Alberta Geological Survey •  Open Data Canada (Pilot) •  Open Data BC

Data Providers

•  GeoGratis – Natural Resources Canada Earth Science Sector •  GeoBC – Government of British Columbia •  GEOweb – District of North Vancouver •  Land Information Ontario – Ontario Ministry of Natural Resources •  Open data shared by individuals •  US National Forest Service •  US National Park Service

Data Used from:

Available Data (sampling of North America): •  Data.gov •  Individual State Data Clearinghouses •  Government Ministries / Departments

Many provinces and municipalities have kept their data locked up (collected with tax-payer money)!!!!!

Data storage / sharing, collaborative mapping Import KML to Google maps “My

places”

Expand user base to utilize open data and communicate with maps
